Overview

PowerXplorer description

The Dranetz-BMI PowerXplorer

TM

PX5 is a portable, hand-held, eight-channel power quality meter/monitor. This cutting-edge power quality instrument is designed with a color liquid crystal display (LCD) 1/4 VGA, using touch screen technology. It can monitor, record and display data on four voltage channels and four current channels simultaneously.

PX5 is designed to meet both the IEEE 1159 and IEC 61000-4-30 Class A standards for accuracy and measurement requirements. It can do PQ-optimized acquisition of power quality related disturbances and events. It is designed with a statistical package called

Quality of Supply (QOS), with monitoring and setup protocols set to determine voltage measurement compliance required for EN50160 monitoring. European standard

EN50160 requires that measurement parameters must be within a specified percentage for 95% of the time.

PowerXplorer PX5 is available in two models:

• Model PX5-XFAST is equipped with the high speed sampling analog board for microsecond transient detection digitization and analysis. The PX5-XFAST performs measurements for 50/60 Hz power frequency systems.

• Model PX5-400 performs measurements for 400 Hz power frequency systems. The

PX5-400 will also monitor at 50/60 Hz. The user needs to set the default frequency to either 400 Hz, 60 Hz or 50 Hz, depending on the application. When operating at 400

Hz, rms calculations are made on a cycle-by-cycle basis with 1 cycle step; whereas at

50/60 Hz mode, it steps at 1/2 Hz. Also, the PX5-400 does not calculate the IEEE

1459 power parameters as well as flicker, which are not defined at 400 Hz.

PX5 Firmware

The firmware for the PX5 is contained on internal FLASH memory. It has an operating system capable of performing multiple applications. When an updated version of the firmware is released, the user can upgrade the internal program by putting the latest

PX5 firmware program card in the appropriate slot of the mainframe. See page 1-10

for instructions on how to upgrade PX5 firmware from a data card.

The PX5 firmware can monitor power quality phenomena for troubleshooting and/or compliance purposes. It can record inrush conditions, carry out long-term statistical studies to establish performance baselines, and perform field-based equipment testing and evaluation for commissioning and maintenance. The firmware integrates an intuitive instrument setup procedure to ensure the capture of all relevant data for additional post process analysis, report writing, and data archiving using other compatible Dranetz-BMI software applications such as NodeLink

®

and DranView

®

PX5 Features

PX5 Features

Touch screen function

All PX5 functions described below are operable using a color LCD touch screen technology. Users may use a finger and/or a PDA stylus to apply pressure to the LCD screen to result in touch screen recognition. The touch screen display is also workable with lineman gloves on. Touch screen buttons will appear in reverse-video to show visual feedback of contact along with audible feedback. In order to reduce power consumption, the backlight of the LCD screen times-out after a specified programmable time of no user activity. The backlight reactivates by touching any part of the screen.

Scope mode

Meter mode

Harmonics

Scope mode functions as an oscilloscope, displaying real-time waveforms of voltage and current for up to eight channels simultaneously, with one second update rate. The colors of waveform display are user programmable. Scope mode also provides a textual display of rms values, division for axis values, and frequency.

Meter mode functions as a true rms voltmeter and a true rms clamp-on ammeter.

Voltage and current measurements, along with other calculated and advanced power parameters, are displayed on the Meter mode screens in both textual and graphical format.

Harmonics display the amplitude and phase of each harmonic to the 63rd harmonic in both graphical and textual format.

Phasor diagram The phasor screen displays a graph that indicates phase relations between voltage and current based upon the angles at the fundamental frequency, as determined by Fourier analysis. Phasor diagram displays voltage and current phasors for all channels.

Functioning as a phase angle meter, the unit can display system imbalance conditions and provides such information in textual form also. The phase angle display can also verify if monitoring connections have been made correctly. Animated phasor demo rotations demonstrating resistive, inductive and capacitive loads can be displayed.

Flicker

Flicker is a phenomenon due primarily to rapid small fluctuations of the voltage. Loads that exhibit continuous, rapid variations in the load current, particularly the reactive component, can cause voltage variations often referred to as flicker. Flicker is characterized by modulation at a frequency typically less than 25 Hz. Modulating signal magnitudes as low as 0.5% of the fundamental for frequencies between 5-10 Hz can result in perceptible light flicker.

Event

An event occurs when a programmed threshold limit is crossed. An event consists of the pre-trigger cycle(s), trigger cycle(s), and post-trigger cycle(s).


1-12


Monitoring capacity

PX5 can monitor the following power configurations:

• Single Phase • 3 Phase 2-Watt Meter Delta

• Split Phase • Generic

• 3 Phase Delta

• 3 Phase Wye

• 2 1/2 Element without V

B

• 2 1/2 Element without V

C

While monitoring any of the above configurations, the PX5 can also be connected to monitor neutral to ground voltage and neutral or ground current.

Automatic setup, Wizard setup, or

Advanced setup

Setup is a configuration of parameter thresholds that control the data recorded by PX5.

Users may perform instrument setup in three ways: via Automatic Setup which utilizes auto-configured settings and allows users to proceed directly with data monitoring; via

Wizard Setup which follows a step-by-step sequence where users go through a series of circuit setup screens; or via Advanced Options setup which allows users to modify trigger parameters and intervals or tweak threshold settings.

Trend

Users can generate plots for all journalled data combined with min/max recordings of that parameter. Most journal parameters have multiple channels to plot.

Reports

Data Card

Users have two options on how to view QOS compliance reports.

EN50160 displays statistical reports on QOS compliance based on an analysis of the voltage as per requirements of the EN50160 standard. Compliance data is presented in bar charts, statistical tables, and graphs. Statistical data is calculated on the required parameters specified in EN50160 over one week interval to produce a PASS/FAIL decision of QOS compliance.

PQ Status presents a status summary for QOS via the annunciator panel. The panel is color coded such that green indicates the parameter is within limits and/or no events have occurred since the last time the panel was cleared. Red indicates the parameter is out of limits and/or events of that type have occurred since last cleared. Unlike the

EN50160 which reports on QOS compliance on a weekly basis, PQ Status monitors compliance continuously. The user may choose to clear or reset existing data on the panel and restart monitoring at a new time and date. PQ Status automatically displays the time and date since the panel was last cleared.

PX5 supports the use of Compact Flash data cards with AT LEAST 32MB storage capacity. The user replaceable data card serves as primary storage for data. Data monitoring CANNOT proceed without the data card. PX5 is designed to accommodate the Compact Flash card in its native format, and does not require the use of a PC card adapter. However, a PC card adapter can be used to read the data into a laptop or other computer with a PC card slot.

Advanced power metering tab meters multiple total apparent power and power factor parameters, calculated using arithmetic and vector sums of the individual phases. These methods may produce different values with distorted and/or imbalance phases.

Demand/Advanced Energy include various energy parameters on per phase and total basis as well as in forward and reverse mode. Some parameters such as displacement power factor are only valid for the fundamental frequency. The Advanced tab also allows trending of rapid voltage changes that result in light flicker. Flicker parameters under the Advanced tab are used primarily for specialized testing. Flicker measurements are calculated as per IEC 61000-4-15.

Section C

Harmonics

Overview

Harmonics display

PX5 allows users to view voltage and current harmonics/interharmonics in graphical or in list form. Harmonics are waveform distortion, a steady-state deviation from an ideal power frequency sinusoid and is characterized by the spectral content of the waveform.

Interharmonics are frequency components between the harmonic frequencies. The IEC

61000-4-7 Standard dictates that harmonic analysis is done using a synchronous window of 10 cycles for 50 Hz, or 12 cycles for 60 Hz. This results in bins which are nominally 5 Hz wide. The actual width of the bins is equal to the actual frequency divided by 10 if the nominal frequency is 50 Hz, and 12 if 60 Hz. For example, if actually operating at 49.9 Hz, the bin is 4.99 Hz, but is labelled “5 Hz” as specified by the standard.

Use the respective touch screen buttons to display the next Channel (Channels A, B, C,

D) and the next Parameter (V, I, W) of harmonic data. The number of harmonics/ interharmonics displayed is up to the 60th. Summary values of odd, even and total distortion are displayed. A summary of harmonic distortion as well as interharmonic distortion values per phase/parameter are also available on display.

Users can determine the number or range of harmonic frequencies to trend and view in detail. There is also the option to select how to plot harmonic/interharmonic data and specify the units of measure by which harmonic data is calculated.

Harmonic Graph: Harmonics are measured in accordance with IEC 61000-4-7 Class 1.

Users can choose the unit of measure by which harmonic data is calculated and graphed, based on a Percentage of the fundamental value or in Engineering units (volts and amps). Frequency components of harmonic graphs can be displayed either in Hertz or in Harmonic Number. The graphs can be zoomed and rescaled.

Harmonic List: The list gives a textual display of the following for each of the measured values: frequency and harmonic number; magnitude in Engineering units and percent of fundamental; phase in degrees (for harmonics only). This list is displayed in order of ascending frequency, and can also be sorted in order of descending magnitude.

*The odd contribution is the square root of the sum of the squares of the relative

amplitudes of harmonics 3, 5, and 7 through N-1, where N is a function of sampling frequency. The even contribution is similar for harmonics 2, 4, and 6 through N. Total value is the square root of the sum of the squares of the odd and even distortions.

Interharmonic data plots

The voltage and current harmonics and/or interharmonics for each phase channel can be trended using the Options button. The properties specified under Harmonic Options apply when harmonic/interharmonic data is viewed in either graph or list form.

Properties under Show Harmonics... pertain to both the graph and the list, and determine how the harmonics and interharmonics are used.

If Show Harmonics... only is enabled, then only the actual harmonics are shown.

If Show Harmonics... and Interharmonics is enabled, the spectrum will include all the (nominal) 5 Hz bins, which includes the actual interharmonics as well. On the graph, the harmonics are shown in the channel color, while interharmonics are shown in gray color. On the text, the harmonics are shown in boldface.

If Show Harmonics... calculated including adjacent interharmonics is enabled, the interharmonics are not explicitly shown but the harmonic values include the adjacent interharmonic values in their calculation, as specified by IEC 61000-4-7.

The IEC 61000-4-7 Standard specifies that the interharmonic bins adjacent to the harmonic be included in the computation of that harmonic. For example, if there was a

3rd harmonic (150 Hz) of 10%, and the value of the 145 Hz bin was 1%, and the value of the 155 Hz bin was 2%, then the value reported in the bin labelled “150 Hz” would also include contributions from the 145 Hz and 155 Hz bins. This would give

Start Menu

Overview

Start menu options

The Start Menu allows users to perform the following: set up the PX5 for monitoring of an electrical system, load previously saved setups from card, and load data from card.

There are three ways to set up the instrument for monitoring. The length of time to monitor a circuit can vary from a few hours to a few weeks depending on the user application.

• Automatic Setup automatically configures the instrument’s circuit type, voltage and current channels, and parameter thresholds. The auto-configured setup enables users to proceed directly with data monitoring.

• Wizard Setup takes the user through a series of screens prompting for information about the circuit to be monitored. The unit automatically turns on the correct voltage and current channels when user selects a circuit type. Parameter thresholds are automatically set based on the line voltage and current values that the user enters.

Threshold limits for capturing events are also set according to the monitoring mode selected.

• Advanced setup options (see Chapter 6) allow the user to modify trigger parameters and intervals that were previously set up through Automatic or Wizard setups. Under advanced setup, each channel must be turned on individually, but any combination can be used. Threshold limits can be set to any value within the acceptable range.

The user can turn on any available parameter. Users have wider control over all setup functions when using advanced setup options.

Selection of setup method typically depend on user application and extent of familiarity with the operation of the intrument.

Monitor same circuit makes use of the existing setup for monitoring. If a template of setups has been previously saved to the card, you may load it using the menu below.

Load setup template from card enables you to use previously saved setups. If you wish to load a previously saved data file from the card, use the menu below.

Load data from card allows you to transfer saved events from data card to PX5.

Wizard Setup

Overview

Introduction

Wizard Setup guides the user through the circuit setup step-by-step, via a series of screens prompting for information about the circuit to be monitored. The unit automatically turns on the correct channels, sets the parameter thresholds and waveform capture settings depending on the detected circuit type, nominal voltage and current values, and monitoring mode specified by the user.

Monitoring modes

PX5 allows users to monitor events in the following setup categories: Standard Power

Quality, Current Inrush, Fault Recorder, Long-term Timed Recording, Continuous Data

Logging, and EN50160 Power Quality mode. Selecting any setup category automatically sets trigger and capture conditions. Advanced users are free to mix and match settings (see Chapter 6 Advanced Setup Options).

Standard Power Quality, Demand, Energy: PX5 algorithms automatically evaluate existing rms and waveform conditions to optimize setups to reliably capture data. This feature ensures that the first-time user gets the expected results, while providing the experienced user with the ability to tweak settings for specific applications. Either way, the necessary data used to identify critical events and optimize mitigation solutions is recorded into the data card as it occurs.

Current Inrush: Determining system characteristics during current inrush conditions such as impedance changes during motor energization or the I

2 t curve of a breaker trip is key to preventative maintenance and enhanced power system performance. Inrushtype events such as motor start-up typically requires extended duration cycle-by-cycle recording. With PX5, users can capture and store detailed data to evaluate system performance against specifications and previous benchmark data. Under the current inrush mode, triggers are current-based. By operating in the inrush mode, the instrument will capture and store highly detailed data to a Compact Flash data card in real time, then rearm and be ready to capture data during the next test run.

Fault Recorder: A fault in a wire circuit is usually due to unintentional grounding, a break in the line, a crossing or shorting of the wires, etc. A digital fault recorder logs extended duration cycle-by-cycle recording. Under the fault recorder mode, triggers are voltage-based. PX5 can help locate failures detected in various components of assorted equipment by recording an extended period of cycle-by-cycle data to capture the entire duration of the fault and the associated system response.

CH 5/ Start Menu

Monitoring modes

(continued)

Long-term Timed Recording, Demand, Energy: Performing a statistically valid power quality energy survey requires the capture of a set of basic data over an extended period of time. PX5 is designed to facilitate long-term monitoring by collecting min/max/avg data at each predetermined interval in order to perform post-process harmonic and other events analysis. PX5 is also designed to be left unattended in the field, recording statistically representative data for long-term analysis. Using the Dranetz-BMI lockable portable case option or other available enclosures, power quality studies can be carried out in harsh weather environments.

Continuous Data Logging, Demand, Energy: This logs the rms and power values once per second for totally gapless logging. Cyclic triggers are disabled. No waveforms are recorded under this monitoring mode.

EN50160 Power Quality: EN50160 monitors and reports Quality of Supply (QOS) compliance as specified by the EN standard. The seven parameters required by

EN50160 to determine QOS compliance are: Power Frequency, Supply Voltage

Variations, Rapid Voltage Changes, Supply Voltage Unbalance, Harmonic Voltage,

Interharmonic Voltage, and Mains Signalling. A full discussion on EN50160 is found on Chapter 7 View Event Data - Section C Reports.

Scale Factor Setup

Scale Factor Setup

What is a scale factor?

A scale factor is the ratio of the input to output for a particular current transformer (CT) or potential transformer (PT). A scale factor is entered in PX5 and then multiplied automatically by the measured voltage or current so the unit displays the correct values, as referenced to the primary side, rather than the secondary side of the PT or CT.

NOTE: If voltage and current connections are made without using any of the above named devices, the scale factor should be set to 1.

When to use

Scale factors must be entered for the following conditions:

• A Dranetz-BMI current probe is connected to a permanently installed CT.

• The current connections are made using a Dranetz-BMI ISO box.

• The voltage connections are made using a PT.

Non-Dranetz equipment

Refer to the CT name plate or to the manufacturer’s literature to determine the scale factor.

Sample calculation

The scale factor for a single CT or PT is calculated from its step-up or step-down ratio.

Example of step-down ratio

If a current transformer has a step-down ratio of 1000A:5A, therefore:

Scale Factor = 1000/5 = 200

Example of step-up ratio

If a potential transformer has a step-up ratio of 1V:10V, therefore:

Scale Factor = 1/10 = 0.1

Nominal Values, continued

Frequency synchronization

Normal frequency synchronization (sync) of PX5 analog signal processing circuits is controlled by analyzing the external AC voltage signal input on channel A. Loss of external sync causes the PX5 to poll other valid voltage channels (A, B, or C) for an alternate external sync. If none exists, then internal sync is automatically selected. The frequency used for internal is entered under Frequency on the Nominal Values screen

(see page 5-14).

Depending on the type of circuit configuration, the instrument will attempt to autosearch to sync to any valid voltage channel. The autosearch function will be disabled when users specify sync mode Ch D Volts. Typically, external sync on Ch D is specified if it is known that signals on A, B or C are inappropriate for use as a sync source (i.e. the frequency is unstable or DC). A low distortion 50, 60 or 400 Hz signal can be input to Ch D and used as a sync signal.

NOTE: Failure to connect an external sync or to select an internal sync during current monitoring will result in erroneous data being collected and displayed.

Frequency tracking

Tracking determines how the phase locked loop circuitry responds to sudden changes in frequency.

Standard mode: On a normal power quality application [Standard], the system is designed to “ride through” voltage changes to keep tracking the fundamental frequency even in the absence of voltage.

Fast mode: When operating on a local generator [Fast], the frequency will vary more as loading changes occur. The Fast mode allows the instrument to follow these changes more closely.

Internal mode: In cases where no reference signal is available (such as DC monitoring), the Internal setting is used to set the sample rate.

NOTE

Standard Power Quality, Demand, Energy optimizes the instrument to collect data for troubleshooting using standard power quality parameters, with numerous trigger conditions set.

Current Inrush is ideal for recording motor start-up and inrush conditions. This setting is used when recording is triggered on change in current with longer cycle-bycycle waveform capture than Standard Power Quality.

Fault Recorder is similar to Inrush but with a voltage trigger.

Long-term Timed Recording, Demand, Energy sets the instrument to use periodic measurements only. This setting is used for long-term statistical studies and benchmarking field-based equipment testing and evaluation. No triggers are set so only trended values are available.

Continuous Data Logging, Demand, Energy sets the instrument to log rms and power values once per second until memory is filled or for specified time period.

Where you can save data

PX5 uses the Compact Flash data card as primary storage for event, journal, and setup data. It automatically saves data in the card when monitoring is on. The Compact Flash card must be installed in either data card Slot 1 or Slot 2 in order to record data.

NOTE: Although PX5 is able to detect availability of data card in either slot, Dranetz-

BMI strongly recommends the use of only one card slot (one data card) at a time.

Data card size

PX5 requires a Compact Flash data card with minimum storage capacity of 32MB, maximum of 128MB. See Appendix A Optional Accessories for the part numbers of

Compact Flash cards supplied by Dranetz-BMI.

NOTE: Dranetz-BMI Compact Flash data cards have been tested to work properly with the PX5. Non-Dranetz-BMI Compact Flash cards may not be compatible with the instrument and cannot be supported by Dranetz-BMI Customer Service in case problems arise. Users are advised to use only Dranetz-BMI parts and accessories.

Guidelines on file data transfer

PX5 treats the Compact Flash data card like a hard disk storing files in DOS format.

For successful card data transfer, keep the following points in mind:

• PX5 supports a maximum DOS directory size of 128MB. Minimum required

Compact Flash data card size is 32MB.

• Compact Flash cards allow users to store multiple files in one card. The Site name will be used as the filename for record files (i.e. if the site name is Power Xplorer

Site, the filename will be Power Xplorer Site00.DDB). A number is automatically appended to the name such that filenames are automatically incremented every time the user starts monitoring with that same filename.

• PX5 does not support file fragmentation. When creating a file, it will take the largest contiguous block and use that size block for data storage. Deleting files from the data card is NOT RECOMMENDED. When there is no more space available to begin new data storage, reformat the card using the PX5, after transferring data files to a computer.

Advanced Setup Options

Overview

Introduction

This chapter describes the options available to users with applications that require advanced setups. Although PX5 is designed to capture data no matter what the setup is, users are able to configure combinations of setups unique to their task applications.

Definitions

Setup: A pre-set condition of parameter thresholds and waveform capture settings for each channel that determines what will constitute an event and what waveform data will be saved when this event occurs.

Event: An event occurs when a pre-set or programmed threshold is crossed. Events result in a contiguous collection of cycles that is saved into memory. An event consists of pre-trigger cycle(s), trigger cycle(s), and post-trigger cycle(s).

Parameter threshold: A value that the PX5 compares to a measurement to decide if an event occurs. Also called a limit. For example, if the input voltage is measured as 135

Vrms, and the parameter threshold for voltage is 132 Vrms, PX5 saves this limit crossing to memory as an event.

CH 6/ Advanced Setup Options

Transient Limit

Transient detection

Dranetz-BMI instruments label rms voltage or current variations as either sags (voltage or current decreases below low limit) or swells (voltage or current increases above high limit) as per IEEE 1159. Voltage disturbances which are shorter in duration than typical sags and swells are classified as transients. Two basic types of transients are:

1) impulsive transients characterized by very rapid changes in the magnitude of measured quantities and commonly caused by capacitors or inductors switching on line, loose wires, lightning, static, and power failures; and 2) oscillatory transients defined as a temporary, rapid discontinuity of the waveform. PX5 has extensive recording capabilities for low and medium frequency transients using the following trigger mechanisms:

• RMS difference cycle-to-cycle

• Crest or Absolute peak (Instantaneous)

• Waveshape cycle-to-cycle magnitude/duration variation

RMS variations

RMS stands for root mean square, a mathematical formula used to measure the average voltage and current behaviors. RMS variations result whenever voltage or current behaviors rise above or fall below the programmed thresholds. See RMS Variation

Limit on page 6-9 for more information on rms variations.

Absolute peak settings

The crest factor or instantaneous peak is the absolute peak sample value within one cycle. The instantaneous peak triggers on the absolute peak value of the entire waveform.

Waveform capture settings

Oscillatory transients are types of disturbances usually captured as waveshape faults.

PX5 captures pre-trigger and post-trigger waveform cycles. The waveshape fault triggering algorithm essentially compares the samples for each cycle to the corresponding samples from the previous cycle. If the samples differ by more than the threshold tolerance for a length of time exceeding window percent of the power frequency cycle, a waveshape fault is registered. A trigger occurs when either waveshape or rms deviation rise above the programmed thresholds. Waveshape trigger values include the magnitude and duration of the difference between the present and previous cycle.

Once a record trigger is detected, instantaneous waveform information is recorded for the prescribed voltage and current channel(s). Disturbance monitoring requires that voltage be continuously sampled, and recorded only if the signals exceed specified values. Waveshape changes are only triggerable for voltage transients as the current waveshapes are usually continually changing on a normally operating distribution system. However most types of disturbances require that current be recorded as well to help determine the source of the disturbance.

6-3

High Frequency Transients

High Frequency Transients

High frequency impulsive transient

High frequency detected transients uses special circuitry to detect and capture transients as small as 1 microsecond in duration. These transients can be positive and/or negative values above or below the low frequency waveshape.

PX5 is designed with the high speed sampling analog board that can capture voltage and current transients. Because these types of disturbances usually exhibit very narrow widths and fast rise and fall times, they are quickly damped by the system. They tend to be unidirectional when close to their source.

6-4


Recording Transients

Procedure to record transient disturbance

PX5 uses four different algorithms to detect and record transients:

• Peak or Instantaneous trigger magnitude

• High frequency negative/positive peak detectors magnitude

• Waveshape threshold duration or window

• Waveshape threshold magnitude or tolerance

Action...


Options screen, press Transient

Limit.

• Press the limit field to change limit. Use the keypad to enter the instantaneous limit. This value is compared against the absolute value of each A/D sample of the V and I channel waveforms.

NOTE: Do not set this value to less than or equal to the peak of the normal waveform. For a sinusoidal waveform, the peak is 1.414 x the rms value.

Failure to do this will result in continuous triggering.

NOTE: The figure above helps illustrate the

, when compared to v i-1 cycle where the deviation in magnitude is outside the maximum allowable deviation, a counter is incremented. For each sample v i

that is within the maximum allowable deviation, the counter, if greater than 0, is decremented. If the count reaches N, a trigger occurs.

RMS Variation Limit

RMS variation setup properties

RMS stands for root mean square, a mathematical formula used to compute the equivalent value of the voltage and current. Voltage and current changes are measured and checked against the programmed limits. Thresholds are set as high limits (threshold above the programmed limit) and low limits (threshold below the programmed limit).

RMS variations result whenever voltage or current rms value rise above or fall below the programmed threshold limits. The limits determine how sensitive the instrument should be (note that statistical and trending information is always captured regardless of the limit settings, so the user will never be without a data even if he/she did not set the limits to the ideal values).

PX5 allows users to set the limits for each of the triggers, as well as the amount of rms sample (cycles) to record before and after trigger cycle.

RMS trigger parameters

In order for the instrument to trigger on rms variation, any one of the measured quantities for which a trigger is enabled must go above the High Limit or below the

Low Limit for a period of at least one rms sample point (which are taken twice per cycle with a one cycle sliding integration window).

The disturbance end point is defined as the cycle when all channels for which triggers are enabled have come back within limits (plus hysteresis) for a minimum duration of

Cycles specified in range to end event. Until this criteria is met, any subsequent excursions beyond the thresholds are considered part of the original disturbance. To minimize the number of triggers recorded for a sequence of closely spaced disturbances, hysteresis is employed in both voltage and time for the begin-event and end-event thresholds.

NOTE: Hysteresis values assigned to limits are set by the system and not programmable by the user.

Journal Limit

Journal Limit

Journal entry settings

PX5 allows power parameters to be trended using periodic readings that are stored in a journal. Statistical information is always captured regardless of the limit settings, so users will never be without a trend even if he/she did not set the limits correctly. The system collects data even when no disturbances occur by recording periodical statistical data (By Time).

Page 6-17 shows one example of how to set entries under the Standard - Basic parameter. The same procedure applies when setting entries under other journal parameters.

Page 6-18 features the list of journal parameters that can be trended.

Logging data by limits

Limit methods allow users to set the threshold units by which high and low limits of voltage trigger and current trigger are calculated. Thresholds are set in ranges with high limit (threshold above the normal range) and low limit (threshold below the normal range). The following threshold limits are used to trend journal parameters:

Very High: specifies an absolute limit for comparison that is higher than the high limit

High: specifies an absolute limit for comparison that is higher than the low limit

Low: specifies an absolute limit for comparison that is lower than the high limit

Very Low: specifies an absolute limit for comparison that is lower than the low limit

Deadband: specifies how much a value can change before another event is recorded

The Very high must be greater than High, Very low less than Low. Deadbands or sensitivity is used to record incremental changes in the parameter besides when limits are crossed. The hysteresis values assigned to limits are fixed and not programmable by the user. All limit values are used to determine if corresponding reporting or logging action should take place.

Logging data by time

PX5 is able to measure periodic samples as well as take snapshots of the voltage and/or current waveform. The Journal Interval menu (see page 6-22) allows users to set the time of how often the instrument will record power parameter values, demand and energy, harmonics, and flicker.

NOTE

Users can record data simultaneously by limits and by time. Make sure to enable the parameters to trend under Journal Categories and Journal Interval.

Journal Interval for Timed Readings

Introduction

The Journal Interval screen allows users to define how often the PX5 saves data periodically, regardless of power quality disturbances and journal limits.

Definitions

Power Values

Power Values Interval - Power parameter values are based upon all cycles during a one second interval. Data is aggregated or summarized into min, max and avg values over the averaging period and stored at the end of the interval. Data measured include watts, power factors, as well as the one-second rms (not to be confused with the one cycle rms). Cyclic min, max and avg are based upon full cycle waveforms with a resolution of one half (1/2) cycle. They record the rms, crest, and waveshape parameters that are also used to capture a snapshot of the waveform. Note that if users did not set the thresholds for rms variations properly, the min, max and avg will still provide a record of what happened during the interval.

Waveform Snapshot- Contains properties that measure periodic sample or snapshot of the voltage and/or current waveform. Users are able to determine how often the instrument will record waveform snapshots by turning the function on or off.

Demand and Energy

Demand Sub-Interval and Sub-Intervals per Interval - Refer to the time interval used in calculating power demand values. Demand calculations are made every sub-interval on the values that occurred during the most recent Demand Interval. Values set for

Demand Sub-Interval must be an integer-divisor of the Demand Interval since the former applies when updating certain parameters of the latter.

Harmonics

Harmonics Journal Interval - Various harmonic parameters such as total harmonic distortion (THD), total interharmonic distortion (TID), and telephone influence factor

(TIF) can be trended using periodic readings that are stored in the journal. Depending on the harmonic journal interval set, the instrument records a sampling of the waveform synchronized to the fundamental frequency, to ensure accurate calculation of harmonic phase angles.

Flicker

Pst (Short Term) Interval - Pst is short term perceptibility, used to set the Pst calculation interval. Typical calculation is over a 10-minute interval, though users can specify Pst

Interval under Flicker.

Plt (Long Term) Interval - Plt is long term perceptibility, used to set the Plt calculation interval. Typical calculation is over a 2-hour interval, though users can specify Plt

Interval under Flicker.

The Plt interval must be an integer multiple of the Pst interval. Sliding Plt recalculates the Plt value at each Pst interval, rather than only at the Plt interval.

EN50160 Power Quality (for strict EN50160 monitoring only)

Advanced setup options for

EN50160

EN50160 is a statistical analysis of power quality data based on the EN standard. The statistical package called Quality of Supply (QOS) is built into the PX5, with monitoring and setup protocols set to determine voltage measurement compliance required for EN50160 monitoring. The EN50160-required measurement parameters include Power Frequency, Supply Voltage Variations, Rapid Voltage Changes, Supply

Voltage Unbalance, Harmonic Voltage, Interharmonic Voltage, and Mains Signalling.

The monitoring site is said to be IN COMPLIANCE if the statistical value over one (1) week for the specified parameters is 95% or greater.

EN50160 Options setup allows users to define up to five mains signalling frequencies below 3 KHz. Users can also select pre-defined values for main voltage characteristics of electricity supplied by Low Voltage (LV) and Medium Voltage (MV) public networks.

NOTE

EN50160 is defined for the electricity supplied at the supply terminals, and does not deal with the supply system or consumer’s installation or electrical equipment itself.

Since the standard deals with the voltage characteristics which can be expected in public distribution networks, other aspects essential for supply quality (i.e. short circuit power) are not treated within the scope of the standard. EN50160 standard is applicable only under normal operating conditions of the supply system.

Overview

Types of data display

PX5 offers a graphical, information-packed, and easy to navigate display of event data.

The firmware architecture of PX5 is designed to engage in various stages of acquisition, characterization, communication, and visualization of event data and journalled data. PX5 also does Quality of Supply or QOS compliance monitoring as specified by EN50160, which requires that measurement parameters must be within a specified percentage for 95% of the time.

Event: An event occurs when a programmed threshold is crossed. An event consists of pre-trigger cycle(s), trigger cycle (fault), and post-trigger cycle(s). A contiguous collection of cycles caused by events is recorded into memory. An event may also contain information about other channels depending on how the user sets up the application.

Trend: A trend is a graph of the value of one parameter and channel over time. Trends aim to show a macro view interface of timespan, trigger conditions, and channels of waveforms and rms that were recorded. Users can zoom in on trends for a more detailed view.

Reports: EN50160 and PQ Status report on data retrieved by the QOS functional components built into the PX5 firmware. Statistical data is calculated on seven parameters specified in EN50160 over one week interval to produce a PASS/FAIL decision of compliance. PQ Status displays the status summary for QOS using the annunciator panel. The color coded panel indicates whether or not the parameter is within limits and/or events have occured since the last time the panel was cleared. PQ

Status monitors QOS compliance on a continuous basis. The user may choose to clear or reset existing data on the panel and restart the time/date from which the panel will display status for journalled data and events.

Voltage and

Current channels to plot

A time plot is a graph of the value of one parameter and channel over time. PX5 is able to display time plots for individual Voltage and Current channels (Va, Vb, Vc, Vd, Ia,

Ib, Ic, Id) or phase-to-phase Voltage channels (Vab, Vbc, Vca), depending on the available channels for Voltage and the selected circuit type.

RMS trigger parameters

RMS variation is the most common type of disturbance and is identified as a specific type of event by IEEE and IEC. Event characterization implemented in PX5 adheres to the IEEE 1159 and IEC 61000-4-30 Class A standards (Refer to Appendix F Event

Classification). RMS values are updated at half-cycle rates, calculated over one cycle and compared against limits on a cycle-by-cycle basis. The high and low limits can be enabled and programmed individually for each phase and phase-to-phase value.

The following parameters are required to define how an rms variation is triggered:

Very Low limit

Low limit

High Limit

Cycles in range to end event

As per IEEE and IEC standards for multi-phase systems, the beginning of the voltage rms event occurs when any phase voltage goes outside the limits, and ends when all of the phases are within limits for an end-event number of cycles specified. This is only true for voltage, not current.

In addition, rms variations can have three stages of averaging or chart rates, which is particularly useful for long duration events to save memory in exchange for reduced resolution. This mode begins if the rms value remains out of limits for longer than the post-start number of cycles that were programmed.

Refer to Chapter 6 Advanced Setup Options for more information on rms variation limits.

What is displayed on a time plot?

A time plot consists of the timed and threshold waveforms for the parameter on display.

Trend

Overview

Trend categories PX5 is able to display statistical trends or plots for the following parameter categories:

Standard: Parameters include basic volts and amps, displacement power factor, residual and net current, energy, harmonics, standard demand, and standard flicker. These power parameters are measured more accurately using a one (1) second interval, summarized by min, max and avg at the end of the interval.

Distortion TIF RMS, THD, Frequency: Parameters include voltage and current THD, voltage and current TID, voltage and current TIF rms, crest factor, signed and unsigned harmonic, and transformer factor.

User Specified Frequency: Users have the option to choose the numbers or range of harmonic frequencies to trend.

Imbalance: Parameters include positive, negative and zero sequence components for voltage and current.

Advanced Power: Parameters include power factor calculated using arithmetic and vector sums of the individual phases.

Advanced Demand: Parameters include peak power, predicted demand, coincident power, and coincident power factor parameters. These parameters measure the ratio of maximum demand of the power distribution system to the total connected load of the system.

Advanced Energy: Parameters include energy on per phase and total basis as well as in forward and reverse mode.

Advanced Harmonics: Voltage and current harmonics and interharmonics for each phase and neutral channel can be trended. Users can enter the number of harmonic frequencies to trend. Harmonics are measured in accordance with IEC 61000-4-7 Class

I.

Reports

Overview

QOS compliance reports

PX5 is designed with a Quality of Supply or QOS statistical package that analyzes and determines voltage measurement compliance, while maintaining the power quality diagnostic capabilities expected from Dranetz-BMI. The QOS compliance monitoring functionality of PX5 is optimized to ensure error-free setup and reporting for EN50160 applications. PX5 also features a PQ Status report summary for QOS via a color coded annunciator panel.

View Reports options

Users have the option to view QOS compliance reports in two ways: via EN50160 or

PQ Status. Each report has their own method of presenting compliance data. Each also differs on the length of evaluation period to monitor compliance. From the Home screen, press Reports.

7-20

MARK470b

EN50160 displays statistical reports on QOS compliance. Statistical data is calculated on the required parameters specified in EN50160 over a one week interval to produce a

PASS/FAIL decision of compliance. The standard monitoring period is one complete week, beginning Sunday 00:00 (midnight). Monitoring periods of less than one week will render an evaluation status that is Incomplete and compliance marked as

Undetermined. Press EN50160 to access the EN50160 statistical reports. See page

7-22.

PQ Status uses a color coded annunciator panel to show a quick status summary of

QOS parameters. PQ Status monitors compliance continuously, until the user chooses

to clear or reset existing data on the panel and restart the time/date from which the panel will display status for journalled data and events. PQ Status automatically displays the time and date since the panel was last cleared. Each parameter on the annunciator panel is linked to a time plot that shows what the values of each of the parameters were over the interval, and at what time did they exceed limits. The plot shows actual voltage or current waveforms that occurred when a certain threshold parameter was crossed. Press PQ Status to access the PQ Status summary report. See page 7-35.

EN50160

What is

EN50160?

EN50160 monitoring mode

EN50160 is a European standard that stipulates the voltage characteristics that can be expected in public distribution networks. The QOS functionality is equipped with monitoring and setup protocols to meet the measurements required for EN50160 monitoring. EN50160 specifies that various parameters must be within a specified percentage for 95% of the standard one week monitoring period.

EN50160 will be able to display data when the instrument has been configured to monitor EN50160 Power Quality. Refer to Chapter 5 Start Menu - Section B Wizard

Setup - Monitoring Mode on page 5-18 for the procedure on how to turn EN50160

Power Quality monitoring on.

EN50160 measurement parameters

Statistical data is calculated based on the parameters required by EN50160 for determining QOS compliance. PX5 displays the parameters in the form of a

Compliance Statistical Bar Chart. From the Reports screen, press EN50160.

7-22

MARK471

The bar chart indicates the percentage of the intervals passing the specified compliance criteria. The color of the bar indicates the compliance status. A green bar indicates that the parameter is within compliance. A red bar indicates that the parameter does not comply with EN50160 Standard. See below for the description of each measurement parameter. For the QOS compliance limit values of EN50160 parameters, refer to the table of Compliance Limits on page 7-24.

Power Frequency: In case of a fault operation, parts of an interconnected system may become isolated. Compliance will be assessed over an observation period of one week, by a statistical analysis carried out over the sequence of 10 seconds measurement.

Frequency is represented by a single value and a single bar. The bar is a hyperlink to the

Power Frequency Graph (see page 7-27).



EN50160 measurement parameters

(continued)

Supply Voltage Variations: Under normal operating conditions, load changes cause variations of the 10 minute average supply voltage. Generally this is compensated by automatic voltage regulation within a period of a few tenths of seconds. Supply Voltage

Variations display a cluster of bars, one for each phase. The color of each bar indicates the compliance status for its phase. A green bar indicates that the parameter is within compliance. A red bar indicates the parameter does not comply with EN50160.

Flicker: Typical rapid voltage changes or flicker do not exceed a magnitude of +5% or

-5% of the nominal or declared voltage. This limitation is possible because connection of loads capable of creating rapid voltage changes is usually subjected to regulations.

However under certain conditions, higher values of up to 10% may occur. These higher values can occur for instance in areas where high power motor equipment (blower, pumps, compressors, etc.) is used. Flickers display a cluster of bars, one for each phase.

The color of each bar indicates the compliance status for each phase. A green bar indicates that the parameter is within compliance. A red bar indicates that the parameter does not comply with EN50160.

Supply Voltage Unbalance: The unbalance of a three phase supply voltage consists of a loss of symmetry of the phase voltage vectors (magnitude and/or angle), created mainly by unbalanced load. Compliance is verified when 95% of the sequence of valid 10 minute values are within the specified tolerance of normally 2% (in single phase/two phase supplies 3%). Supply Voltage Unbalance is represented by a single value and a single bar. The color of the bar indicates the compliance status for each phase. A green bar indicates that the parameter is within compliance. A red bar indicates that the parameter does not comply with EN50160.

Harmonic Voltage: Harmonic displays a cluster of bars, one for each phase. The color of each bar indicates the compliance status that is calculated by adding the status of

Total Harmonic Distortion (THD) and Harmonics 2 thru 25. The bars for Harmonic

Voltage is a hyperlink to the Harmonic graph (see page 7-27).

Interharmonic Voltage: Interharmonic displays a cluster of bars, one for each phase.

The color of each bar indicates the compliance status that is calculated by adding the status of Total Interharmonic Distortion (TID) and Interharmonics 2 thru 25. The bars for Interharmonic Voltage is a hyperlink to the Interharmonic graph (see page 7-27).

Mains Signalling: Mains Signalling is represented by a single value and a single bar.

The color of the bar indicates compliance status that is calculated by adding the status of each of the defined frequencies (a maximum of five) for its phase. Users can specify the signalling frequency values under Advanced Options (see Chapter 6 Advanced

Options for EN50160 Power Quality on pages 6-23 to 6-24). A green bar indicates that the parameter is within compliance. A red bar indicates that the parameter does not comply with EN50160.

NOTE

MARK480

Many instruments used for harmonic measurements of power supply systems express their output with reference to the fundamental component of the voltage, especially those indicating the THD factor.

Harmonic and Interharmonic values are specified only up to order 25 (EN50160 limit), for the practical reason that for higher orders, the values are generally so small as to be impractical to measure. Another reason is because of the difficulty of giving values which would be relevant to all networks.

QOS Status

Summary

EN50160 provides a historical summary of the QOS compliance evaluations made. The standard monitoring period is one week, usually beginning Sunday at 00:00 (midnight).

Any compliance evaluation performed in less than one week will receive an Evaluation

Status marked as Incomplete, and Compliance marked as Undetermined. For completed monitoring periods, Compliance status may either be PASS or FAIL if all of the specified parameters is within limits for 95% or more of the monitoring time period.

A PASS or FAIL status is hyperlinked to the Compliance Statistical Bar Chart.

PASS (green) or FAIL (red) status is linked to the Compliance Statistical Bar Chart (p. 7-27)

Evaluation Status: The EN50160-specified compliance evaluation period is a 7-day

(one week) period. The evaluation status is Complete if monitoring is done within one full week, or Incomplete if monitoring is done in less than one week. An evaluation status is Incomplete under the following scenarios:

• It is the current evaluation period and it has simply not completed.

• It is a previous evaluation period but not enough data samples were included in the statistical analysis. This may be due to the following reasons: data was not collected or too many samples were tagged as unusable due to rms variations.

To download events from PX5 through the optical port, you must have the following: a personal computer or laptop with Windows

®

operating system with either RS232 serial port or network adapter, NodeLink

®

, and the appropriate Isolated Communications

Module assemby as described below.

The Isolated Communications Module assembly consists of two parts:

1. A fiber optic cable (P/N 900406) which connects the PX5 optical serial port to the

PX5 communication module;

2. The PX5 communication module which is available in three types:

• a 9-pin RS232 Communication Module (P/N COMM-RS232)

• a USB Communication Module (P/N COMM-OUA)

• an Ethernet Communication Module (P/N COMM-OEA)

The PX5 communication modules are optically isolated devices using infrared light to transfer text and graphics to a computer running NodeLink

®

. These modules are designed to connect the PX5 optical serial port to the appropriate interface - either a standard RS232 serial port connector, USB adapter, or Ethernet adapter.

With NodeLink

®

you will be able to download data, upload or download instrument setups, or view real time meter data from PX5. The downloaded data can be viewed using the DranView

®

application.

Each adapter interface is supported using the computer’s standard serial ports.

Modem

When configuring both the PX5 and NodeLink

®

for modem communications, keep in mind that the PX5 uses a fiber optic serial port in order to maintain electrical isolation.

This means that there are no control signals available to a modem to use for handshaking and flow control.

It is highly recommended that identical modems be used on the PX5 and the computer.

Identical modems will have the same internal buffering and are more likely to negotiate modulation, speed, and error correction suitable to both modems. If the modems used are not identical then both the PX5 and the computer should have modems with the same chipset (i.e. Rockwell, Lucent).

When configuring for modem communications, the first decision to be made is the port speed for both ends of the communications link. This is the speed at which the PX5 communicates with its modem and the speed at which the computer communicates with its modem. The same speed should be chosen for both. Ideally the speed should be at or just below the anticipated modem connect speed. Since most modems today will attempt to connect at least at 56 kbps, 38.4 kbps would be a good choice for the two port speeds. This helps to prevent possible modem buffer overflow.

Follow the steps below to configure the PX5 for a port speed of 38.4 kbps. See Chapter

4 Instrument Settings - Communications for the PX5 screen interface.

1. Connect the modem to the PX5 communications adapter.

2. Turn on the modem.

3. From the PX5 home screen, click on the Preferences icon.

4. Choose Communications from the Instrument Settings Setup Menu.

5. Verify that both the Enable Communications and External Modem Connected checkboxes are enabled (checkboxes checked).

6. Check to enable 38400 under Baud Rate (bps).

NOTE: The port speed of 38400 (38.4 kbps) used above may be substituted with

57600. Experiment to find the maximum port speeds that will work for the system.

7. Note the modem initialization string at the bottom of the screen. Do not exit this screen yet since you may be modifying this string after you have the Windows

®

modem configured.


7-43



Modem

(continued)

NodeLink

®

uses Windows

®

TAPI when accessing modem communications resources.

The assumption is that the Windows

®

modem to be used for PX5 communications has been properly installed prior to executing this procedure.

If the modem is not on, or was not on when Windows

®

was started, it may be necessary to turn the modem on and restart Windows

®

. Windows

®

looks for installed serial modems at startup. If it does not find them, it may not allow them to be configured in the Control Panel.

Follow the steps below to configure the port speed for the Windows

®

modem in the computer:

1. Press the Start button.

2. Select Settings and then Control Panel.

3. Double-click on Phone and Modem Options.

4. Select Modems in the subsequent dialog box.

5. In the list of modems that is displayed, click to highlight the modem in question and select Properties.

6. On the General tab of the modem properties dialog box, select 38400 as the maximum port speed.

7. Click OK to exit from the open dialog boxes.

8. Close the Control Panel.

It is important to note that the port speed of 38400 (38.4 kbps) may be substituted with

57600. Experiment to find the maximum port speeds that will work for the system.


7-44



Modem

(continued)

Back at the PX5, the last step in configuring the modem communications is to modify the modem initialization string to match the modems and chipsets being used. The goal is to configure for the following:

• Restore factory settings.

• Set auto-answer to answer on one or two rings (more than two rings are allowed but at some point the number of rings may start to conflict with NodeLink

®

timeouts).

• Turn hardware flow control off since you are using a "two-wire" connection (fiber optic port).

• Set a modem inactivity timeout of 60 seconds. The modem will hang up after one minute of continuous inactivity on the line.

• Select the minimum allowable baud rate.

Follow the steps below to change the modem initialization string. See Chapter 4

Instrument Settings - Communications for the PX5 screen interface.

1. From the PX5 Communications Settings screen used to configure modem connection speed, click on the Change button to the right of the string field display.

2. Use the virtual keypad that appears on the screen to change and enter the new string command. The modem initialization string commands for the Conexant (Rockwell) chipset and the Agere (Lucent) chipset are discussed in the next section.

3. When done, click on OK to accept changes in modem communications settings.

Modem initialization string command

The following is the AT initialization string for a modem using the newer Conexant

(Rockwell) chipset:

AT&F;S0=2;+IFC=0,0;S30=6

Where:

AT is the modem attention command

&F instructs the modem to restore factory configuration

S0=2 turns auto-answer on and sets the number of rings to answer to two.

+IFC=0,0 turns flow control off.

S30=6 sets a 60 second inactivity modem hang up timeout.

; is a command delimiter.

NOTE: It may be necessary to adjust the modem connection speeds to specify a minimum baud rate. This is possible using the +MS modem command. Check the modem manual for use of the +MS command. There are several varieties of the command. Typically, a modem modulation scheme and minimum and maximum transmit and receive speeds can be specified. Using Hyperterminal, it is possible to get a list of the possible command ranges and syntax by typing AT+MS=?.


7-45


Modem initialization string command

(continued)

The following is the AT initialization string for a modem using the Agere (Lucent) chipset:

AT&F;S0=2;&K0;%E0;S30=6

Where

AT is the modem attention command.

&F instructs the modem to restore factory configuration.

S0=2 turns auto-answer on and sets the number of rings to answer to two.

&K0 turns flow control off.

%E0 disables baud rate fall back/fall forward.

S30=6 sets a 60 second inactivity modem hang up timeout.

; is a command delimiter.

A similar note regarding connect speeds applies. Try using the AT-V90= command and modifying the contents of S registers S37 and S38 .

TR2510/A, TR2520/A, TR2019B, TR2021, TR2022, TR2023. PX5 supports both

LEMFLEX and DRANFLEX current probes. Typical current probes are illustrated in

Chapter 2.

TR2500, TR2510, TR2520 (TR2500A, TR2510A, TR2520A): These models will measure rms currents from 10 to 500 A, 0.1 to 500 A, 300 to 3000 A, respectively.

They plug directly into any of the current inputs on the rear panel. These probes are not recommended for measuring medium or high frequency transients.

TR2021, TR2019B, TR2022, TR2023: These four probes are made for the Dranetz-

BMI model 658 but can be used with the PX5 by using an adapter cable (part number

CA-4300). They can measure rms currents in ranges of 1 to 30 A, 1 to 300 A, 10 to

1000 A, and 10 to 3000 A, respectively, and are needed to accurately measure medium and high frequency transients.

LEMFLEX Current Probes: LEMFLEX optional current probes allow current measurements in the range of 5 to 3000 A full scale, or 10 to 6000 A full scale.

LEMFLEX probes are available in three sizes: 24” probe length - conductor(s) up to 8” diameter; 36” probe length - conductor(s) up to 11” diameter; 48” probe length - conductor(s) up to 17” diameter.

DRANFLEX Current Probes: DRANFLEX optional current probes allow current measurements in the range of 5 to 3000 A full scale, or 10 to 6000 A full scale.

DRANFLEX probes are available in three sizes: 24” probe length - conductor(s) up to

8” diameter; 36” probe length - conductor(s) up to 11” diameter; 48” probe length - conductor(s) up to 17” diameter.

DRANFLEX4300 probes are battery powered only, supplied with a standard 9V alkaline battery.

WARNING

WARNING


To avoid the risk of electric shock or burns, always connect the safety (or earth) ground before making any other connections.

To reduce the risk of fire, electrical shock, or physical injury it is strongly recommended to fuse the voltage measurement inputs.

Fuses must be located as close to the load as possible to maximize protection.

For continued protection against risk of fire or shock hazard replace only with same type and rating of recommended fuse.

Use only fast blow type fuse which is rated 600V. Recommended fuse type is

Littelfuse, part number KLKD.300 rated 600V AC/DC, 0.3A fast blow.

Do not replace fuse again if failure is repeated. Repeated failure indicates a defective condition that will not clear with replacement of the fuse. Refer condition to a qualified technician.





• Set the PX5 power switch to Off.

Voltage and current connections

This section contains diagrams of both voltage and current probe connections that are required when power measurements are to be made.

Voltage: Voltage probes are connected to the individual source or load line and are referenced to the return (common) line voltage probe connection for greatest accuracy.

Current: Current probes are connected to each line and positioned to measure currents with reference to the voltage probe. Incorrectly positioned current probes may produce erroneous power measurement. Current probes are always oriented with the arrow pointing to the load.

Phasor diagrams

Correct phasor diagrams (for resistive loads) are shown for each connection.

Verifying Voltage and Current Connections

Introduction

Correct voltage and current connection of single phase, split phase, or polyphase connections can be verified using phasor diagrams. Phasor diagrams are graphic representations that show the magnitude and angular relationship of voltage and current for each phase of a monitored connection. Each connection diagram on the following pages shows the correct voltage and current phasor diagrams (for resistive loads) for that circuit.

Displaying the screen

To display the Voltage and Current Phasor screen, from the Home screen press Phasor.

The following screen depicting Positive Sequence 3 Phase Delta resistive load will appear.

Split phase

MARK241

The touch screen Demo button presents an animated phasor demo rotation for resistive, capacitive and inductive loads.

Single Phase resistive load

A single phase voltage or current phasor is displayed as a single line showing a channel reference at 0 degrees and a magnitude relative to its measured value. An arrow head on the line indicates direction.

Split phase vectors are displayed as dual lines showing channel references and magnitudes and opposite (180 degrees) directions.

Three phase

Three phase vectors are displayed as three lines, 120 degrees apart in a resistive load

(unity power factor). Phase displacement will occur in a reactive or capacitive load.


E-5

Verifying Voltage and Current Connections, continued

Incorrect current phasor diagram

Phasor displays that show incorrect current probe connection can be corrected by reconnecting the probe so that the arrow on the probe handle points toward the load.

PX5 is able to display diagrams of wiring configurations to assist users in the selection of circuit type appropriate for their application (see Chapter 5 Start Menu - Circuit Type

Selection on page 5-12). The instrument compares the detected voltages, currents, and phase sequence (if applicable) to the selected circuit type. PX5 issues a message if the specified circuit type and the actual voltage/current connections match.

The next pages describe and illustrate the wiring configurations available for set up in

PX5.

WARNING

Interconnect Jumpers bearing part number 114013-G1 supplied with the standard cable set can be used to bond the same conductor points together. To reduce the risk of fire, electric shock, or physical injury, it is strongly recommended that connections be made with all circuits de-energized and current carrying conductors fused. If it is necessary to make connections on energized circuits, these must be performed by Qualified

Personnel ONLY with proper Personal Protective Equipment.

Connecting to a Potential Transformer

Safety

Precautions

NOTE

Follow the safety precautions listed on page E-3 when making all potential transformer connections.

Potential Transformers are not manufactured by Dranetz-BMI and are discussed here for informational purposes only.

Definition

WARNING

A potential transformer (PT), also referred to as a voltage instrument transformer, provides the necessary step-down ratio to reduce the high voltage of circuits above 600

Vrms to a level for safe measurement. A PT also provides isolation and proper connections for instrument attachment.

Connections

PTs are usually fixed in position and require that the voltage probe(s) be connected to their terminal connections.

Refer to the manufacturer’s instructions, related to the PT, for exact information for probe connection for voltage monitoring. Do not exceed 600 Vrms input to the

PX5 voltage inputs.

ADVERTENCIA Consulte las instrucciones del fabricante referentes a TP (transformador potencial), para la información exacta de la conexión de sonda a fin de monitorear

el voltaje. No supere la entrada de 600 Vrms a las entradas de voltaje de PX5.

AVERTISSEMENT

Se reporter aux instructions du fabricant relatives au transformateur de tension

(Potential Transformer - PT) pour obtenir les renseignements exacts sur la connexion de sonde utilisée pour la surveillance du courant. Ne pas dépasser

l’entrée de tension efficace de 600 RMS dans les entrées de tension de PX5 volts.

WARNUNG

Genaue Informationen zur Meßfühlerverbindung für die

Spannungsüberwachung entnehmen Sie bitte den Anleitungen des Herstellers

(siehe Spannungsteilertransformator). Die Eingangsspannung von 600 V

(Effektivwert) in die PX5 Spannungseingänge sollte nicht überschritten werden.

E-15

Connecting to a Potential Transformer, continued

Procedure

Follow these steps to connect voltage probes to a potential transformer.

Step

1

2

3

4

Action

Turn off power to the PT.

Connect the colored voltage probes to the channel inputs on the PX5 top panel.

Connect the colored voltage probes to the PT’s connections in accordance with the manufacturer’s instructions.

Turn on power to the PT.

Scale factor

The scale factor of the PT must be accounted for in making accurate voltage measurements. Because the monitored output voltage of the PT is stepped-down

(divided) from the original voltage, this ratio must be stepped-up (multiplied) by the

PX5 when voltage computations are performed. The PT scale factor is usually mounted on the PT assembly and is entered into the PX5 on the scale factors screen (refer to page 5-10). Refer to the PT manufacturer’s literature for the scale factor of the device you are using.

E-16


Connecting to a Current Transformer (CT)


WARNING

The following safety precautions apply to current transformer (CT) connections in addition to those safety precautions stated on page E-3.

• Never energize a CT with the secondary open.

• Never disconnect the secondary of a CT with primary energized.

Refer to the manufacturer’s instructions related to the CT for exact information for connections for current monitoring. Do not exceed manufacturer’s ratings.

ADVERTENCIA Consulte las instrucciones del fabricante referentes a TC (transformador de corriente) para la información exacta de las conexiones a fin de monitorear la corriente. No exceda las capacidades nominales del fabricante.

AVERTISSEMENT

Se reporter aux instructions du fabricant relatives au transformateur de courant

(Current Transformer - CT) pour obtenir les renseignements exacts sur les connexions utilisées pour la surveillance du courant. Ne pas dépasser la puissance recommandée par le fabricant.

WARNUNG

Genaue Informationen zu Verbindungen für die Stromüberwachung entnehmen

Sie bitte den Anleitungen des Herstellers (siehe Stromumwandler). Die

Grenzwerte des Herstellers sollten nicht überschritten werden.

NOTE

Description

Current Transformers are not manufactured by Dranetz-BMI and are discussed here for informational purposes only.

Current transformers, also known as instrument transformers, reduce high level currents to low level currents so they can be safely monitored. These devices are similar to PTs used for voltage measurements in that both reduce values for safe measurement. The reduction, or step-down ratio, is stated as a scale factor that is used by the PX5 to step-up the measured value to its original value.

Types of CTs

There are single-phase CTs and polyphase CTs dependent on the source transformer used. Current reduction ratios vary widely and are also dependent on the source transformer used. Rating plates attached to the CT provide information as to the ratio and current limitations.

E-17

Connecting to an Isolated Current Transformer

Connecting to an Isolated Current Transformer (ISO)

Introduction

Low current monitoring devices made by Dranetz-BMI are called isolated current transformers or ISO boxes. The Dranetz-BMI ISO box has a 5 A current range.


WARNING

The following safety precautions apply to ISO box connections in addition to those safety precautions stated on page E-3.

• Never energize an ISO box with the secondary open.

• Never disconnect the secondary of an ISO box with primary energized.

Physical injury or equipment damage could result if ISO boxes are improperly connected. Do not connect an ISO box between two conductors which are at different voltage potentials.

ADVERTENCIA Podrían producirse lesiones físicas o daños al equipo si se conectan indebidamente las cajas del transformador aislado de corriente (ISO). No conecte una caja del

ISO entre dos conductores que tengan distintos potenciales de voltaje.

AVERTISSEMENT

Une mauvaise connexion des transformateurs d’intensité isolés (ISO) peut provoquer des blessures corporelles ou des dégâts matériels. Ne pas relier les transformateurs ISO entre deux conducteurs de tensions différentes.

WARNUNG

Falsch angeschlossene ISO-Kästen (Isolierte Stromumwandler) können zu körperlichen Verletzungen oder Geräteschäden fuehren. Schliessen Sie einen ISO-

Kasten nicht zwischen zwei Leiter mit unterschiedlichem Spannungspotential.

Connections to

ISO box

The ISO box has terminal posts labeled X1 and X2 that are connected in series only with an ac current source. In normal connections, where phasing of current and voltages are important for power measurements, the X1 terminal is connected towards the source input line.


E-18


Connections to

ISO box

(continued)

When connecting to CTs, the X1 terminal is normally connected to the H1 terminal of the device for correct reference phasing.

Where power measurements or voltage/current phase relationships are not important, the X1 and X2 terminals may be connected in series with the output device in any line

(hot or return) or in any relationship of X1/X2.

Applications

ISO boxes can be used in a number of ways. These methods include:

• connecting them to the secondary of CTs for metering by the PX5.

• inserting them in series with the load current to measure low current values.

• connecting them to a non-Dranetz clamp-on current transformer and using that CT to monitor current with the PX5.

ISO box connection to a current transformer

The figure on the next page shows an ISO box connected from any current channel input to a permanently installed CT. The connection shown is made in the load return line for current monitoring only. Polarities of the ISO box and CT are kept in-phase by matching markings of X1 to H1. Scale factors of both devices must be multiplied together to get the resultant scale factor. The scale factor value calculated for a CT is

3.375.


E-19

Connecting to an Isolated Current Transformer, continued

CAUTION

DO NOT exceed current limits of the ISO box.

PRECAUCION

NO exceda los límites de corriente de la caja del ISO.

ATTENTION

NE PAS dépasser les limites d’intensité du transformateur ISO.
