READ CAREFULLY BEFORE

USING FOR THE FIRST TIME

Your instrument is equipped with a NiMH battery. This technology offers several advantages:

• Long battery charge life for a limited volume and weight.

• Possibility of quickly recharging your battery.

• Significantly reduced memory effect: you can recharge your battery even if it is not fully discharged.

• Respect for the environment: no pollutant materials such as lead or cadmium, in compliance with the applicable regulations.

After prolonged storage, the battery may be completely discharged. If so, it must be completely recharged.

Your instrument may not function during part of this recharging operation.

Full recharging of a completely discharged battery may take several hours.

NOTE: In this case, at least 5 charge/discharge cycles will be necessary for your battery to recover 95% of its capacity.

To make the best possible use of your battery and extend its effective service life:

• Only use the charger supplied with your instrument. Use of another charger may be dangerous.

• Only charge your instrument at temperatures between 0° and 40°C.

• Comply with the conditions of use defined in the operating manual.

• Comply with the storage conditions specified in the operating manual.

NiMH technology allows a limited number of charge/discharge cycles depending significantly on:

• The conditions of use.

• The charging conditions.

Do not dispose of the battery pack with other solid waste. Used batteries must be entrusted to a qualified recycling company or to a company specialized in processing hazardous materials.

CHAPTER 2

PRODUCT FEATURES

2.1 Description

The easy-to-use, compact and shock-resistant PowerPad

®

Model 8335 is a threephase power quality analyzer equipped with four current probes and five voltage inputs. It is intended for technicians and engineers to measure and carry out diagnostic work and power quality work on one, two or three phase low voltage networks.

The PowerPad’s 2GB of memory is conveniently partitioned to let you store four different types of data, synchronized or independent of each other. You can store up to 50 screen snapshots, up to 210 captured transients that contain four cycles for each active input, and 10,000 alarm events from up to 40 different parameters.

You can also record trend data for days, weeks or even months.

Six access buttons quickly display the following functions. Note that these functions can be accessed during a recording.

Waveforms – Display Volts, Amps, THD and Crest Factor by phase or for all phases. You can display all the voltage inputs on one screen, phase-to-phase or phase-to-neutral. Real-time phasor diagrams can be displayed for volts and amps, also by phase or for all phases including phase unbalance.

Harmonics – Display Harmonics out to the 50th for Volts, Amps and VA.

Individual Harmonics are displayed as a percentage and value for Volts, Amps and VA. Harmonic direction and sequencing can also be displayed.

Transients or Inrush Current – Set, capture and display transients. You select the threshold and the number of transients to capture. The PowerPad

®

then captures four waveforms for each transient; the triggering waveform as well as one pre-triggered and two post-triggered waveforms. As many as 210 transients each consisting of 4 waveforms per channel for up to 8 channels can be captured.

Trend Recording – Record and display trend data at user selectable sample rates from 1/sec to 1/15 minutes and user programmable recording periods into

2GB of memory.

Recordings can only be downloaded through the USB port. Extremely long recordings will take a long time to download (> 2H per 100MB). Also, keep in mind that Microsoft

®

Excel is limited to 10,000 lines per spreadsheet and Access has limitations as well.

3.2.4 Current Probe Accuracy

(to be added to the PowerPad’s accuracy)

Sensor errors are offset by a typical correction inside the device. This typical correction, applied to the phase and amplitude, depends on the type of sensor connected (detected automatically) and the gain in the current acquisition channel used.

The RMS current measurement error and phase error are additional errors

(which must therefore be added to the device errors), indicated as influences on the calculations carried out by the analyser (powers, energies, power factors, tangents, etc.).

6.5.3 Alarm Conditions Configuration

The Alarm Conditions tab allows you to set up 40 alarm configurations.

Figure 6-8

• Schedule Alarm Search: Check this box to activate the alarms, and set a starting and ending time and date to assign the time period during which the alarms will be active.

• Prev Page & Next Page: Move between the 4 pages of alarms with 10 alarms per page.

• Capture Parameter: The Alarm will be triggered based on the value of the selected parameter.

Choices include:

None: no alarm

Vrms: voltage root mean squared

Urms: voltage phase minus phase root mean squared

Arms: current root mean squared

VPST: voltage short term flicker

Vcf: voltage crest factor

Ucf: voltage phase minus phase crest factor

Acf: current crest factor

Vunb: voltage unbalance

Aunb: current unbalance

Hz: frequency

Akf: current K factor

Vthd: voltage total harmonic distortion

Uthd: voltage phase minus phase total harmonic distortion

Athd: current total harmonic distortion

W: active power


99

• Harmonic Number: For alarm parameters, Vh, Ah, Uh, and VAh, selects which harmonic number is being used as an alarm condition. For example,

Vh with a harmonic number of 2, will only look at Voltage phase to neutral, harmonic 2.

• Phases: Some alarm conditions have a phase selection. W, VAR, and VA, have a choice of “3L” (each individual phase), or “Sum” which is the sum of phases. DPF, PF, and TAN have the choice of “3L” (each individual phase), or “Mean” which is the mean of phases.

• Threshold: The value that must be reached to start an alarm. For “>” alarms, the value or higher must be reached, for “<” alarms, the value or lower must be reached.

• Duration: The Alarm will only be recorded if the duration of the parameter meeting the threshold criteria exceeds the duration. The minimum alarm duration can be in minutes or seconds. In the case of Vrms, Urms or Arms not using neutral current, can also be in hundredths of a second.

For Vrms, Urms, and Arms, it can be useful to set a duration of 0 seconds. In that case an event as short as a half cycle can be detected (8 milliseconds at

60Hz). For all other parameters, the minimum duration that can be detected is 1 second.

• Hysteresis: This value for alarms is set to prevent multiple recordings of an event that goes above the threshold and a certain percentage below it at times.

Example: Alarm threshold is 100 Volts or higher, hysteresis is 1%. When the voltage goes up to 100V, the alarm condition starts. When it goes back down to

99V, the alarm condition stops.

NOTE: You can configure alarms, recordings, inrush, and transient searches while testing is in progress.

6.5.4 Recordings Configuration

The Recordings tab shows the parameters for a recording session.

Figure 6-9

Four different configurations are available. More configurations can be saved by pressing “Save to File” and recalled later by pressing “Load From File”.

1. Select the configuration to set up: 1, 2, 3 or 4.

2. Check the box for each parameter desired in the “Data to Record” section.

3. Configure the harmonic values to be recorded, if desired.

It is possible to record up to 2 of 4 types of harmonic data, voltage

(Vh), current (Ah), phase to phase voltage (Uh), and power (VAh).

For each selected harmonic data type, you can choose a range of harmonics to record from the 1st to 50th. You can further limit that range to only include odd numbers by checking the box for “Odd Harmonics Only”.

4. Check the box next to “Schedule Recording” to activate the recording function. Choose a starting and ending time to assign a time period for the recording to run. Enter a name for the recording (up to 8 characters), if desired.

5. Choose an “Averaging Period” for the recording, which sets how often the recording updates while it is running.


101

The PowerPad

®

loses its scheduled recording if it is powered off before the recording begins. If it is powered off during the recording, a partial recording will usually still exist but with the first letter of its name changed to “@”. The start and end times requested for the recording might be adjusted by the PowerPad

®

to be in even multiples of the averaging period. For instance, if an integration period of 10 minutes was requested, and the start time was 9:03, the recording might not actually begin until 9:10.

6.5.5 Transients

The Transients tab allows you to set up the criteria for capturing transients.

Figure 6-10

1. Click the check box next to “Schedule Transient Search” to activate the transient search function.

2. Type a name for the session, up to five characters.

3. Select the date and time to begin and end the search for transients.

4. Select the percent deviation for voltage and current transients. The choices available from the drop-down menu are 1, 2, 5, 10, 20, 50 and 100% of the full scale range of measurement.

5. Select the maximum number of transients to capture (from 1 to 210).

6.5.7 Monitoring

The EN50160 standard defines limiting values and permissible variations of the voltage quality for the European Community. It defines which parameters are relevant, and how are they measured. Continuous or random sampling control of the voltage quality provides the supplier of electric energy with a reliable basis when dealing with network problems, and it contributes to quality assurance.

The purpose of the EN50160 standard “Voltage characteristics of electricity supplied by public distribution systems” is to specify the characteristics to the customer of the supply voltage with regard to the course of the curve, the voltage level, the frequency and symmetry of the three phase-network at the interconnecting point.

The goal is to determine limiting values for regular operating conditions.

However, facility defects may lead to major disturbances in the electricity distribution supply network. Accordingly, the standard establishes these values as limiting values, which are not allowed to be exceeded on the high or low side during 95% of the controlled period, typically one week.

Figure 6-12

Configure and start an EN50160 test of line quality. Note that It is recommended that a brief test of 10 minutes or shorter be done first, to verify that the connections and parameters of the test are correct. Only then should the 1-week test be done.

If neither of the voltage profiles are chosen, a field appears to enter the nominal voltage. The frequency is not asked for, since it will be asked for when the test result is downloaded.

Follow the instructions in the dialog box to set up and run this special test. Press the Help button for further instructions.

6.8 Saving Real-time Measurements

Real-time data received from an instrument can be saved directly into a recording session database. This differs from the process of downloading and saving recorded data in that the measurements are stored on the computer as the instrument measures them. These measurements are not necessarily being stored within the instrument. However, the instrument may be configured to record at the same time real-time measurements are being received from the instrument. In which case, two copies of the measurements will be stored. One copy is stored on the local computer and the other in memory within the instrument.

To Save a Real-time Measurement:

1. From the Realtime Trend window, check the

“Rec to PC” checkbox.

2. In the Save As dialog box that appears, specify the type of file to save in the

“Save as Type” field. The choices are .dvb (DataView database), .xls (Excel spreadsheet), or .csv (Comma Separated File). Specify the name of the file by typing it into the File name field, select the desired location to save the file, then click Save to save the file.

3. When the “Rec to PC” option is unchecked the file can be opened by selecting

“Yes” from the View Saved File dialog box.

To edit the Session Properties, return to the Power Analyzer Control Panel and select File > Edit Session Properties.


109

Figure 6-17

The Session Properties dialog box allows you to specify the Operator, Site and

Custom parameters that are to be saved with recorded data. These parameters are used when generating reports.

The Operator and Site tabs allow you to maintain lists of operators and sites, saving you time when specifying parameters for reports.

On the left of the Operator and Site tabs is the list of previously defined Operators and Sites. On the right of the Operator and Site tabs is the individual parameters that will be saved in an associated database. Only a single set of operator and site fields are saved in the recording database.

The Custom tab contains a list of user defined parameters. Along side each user defined parameter is a check box. Items that are checked will be added to an associated database. Only a single set of Custom parameters can be maintained

(unlike the Operator and Site lists). The Custom tab allows you to specify any user defined parameters (in addition to the comments field of the Site tab) that are to be used in displaying a report.

Harmonic Calculations

(excluding neutral – over 4 consecutive periods every second)

Harmonic bins are calculated by FFT with 16 bit resolution (1024 samples on 4 cycles) without windowing (IEC 1000-4-7). From the real parts bk and the imaginary parts ak, the harmonic factor is calculated for each order (j) and for each phase (i) (Vharm[i][j], Uharm[i][j], and Aharm[i][j]) with respect to the fundamental and the angles Vph[i][j], Uph[i][j], and Aph[i][j] with respect to the fundamental.

This calculation is accomplished using the following principle:

Hysteresis

Hysteresis is a filtering principle, often used after the threshold detection has occurred. A correct setting of hysteresis value will avoid repeated triggering when the measure is varying close to the threshold.

The event detection is activated when the measure is going over the threshold but it can only be deactivated if the measure goes under the threshold minus the value of the hysteresis.

The default hysteresis value is 2% of the reference voltage but it may be set in the range of [1%, 5%] depending on the voltage stability on the system.

Mechanism for triggering transient sensors

The sample rate is a constant value equivalent to 256 samples per cycle. When a transient search is launched, each sample is compared to the sample from the preceding cycle. The preceding cycle matches the middle of the tube; it is used as a reference. As soon as a sample leaves the tube, the trigger event comes; representation of the transient is then captured by the PowerPad

®

. The cycle preceding the event and the three following cycles are saved to memory.

Phase and route: a measurement route corresponds to a difference in potential between two conductors. A phase is a simple conductor. In polyphased systems, a measurement route can be between two phases or a phase and neutral or a phase and earth or neutral and earth.

Phase displacement factor: relationship between the active power and apparent power of the fundamental component.

Power displacement factor: expresses the difference between the apparent and active power when and only when the relationship of the voltage phase and current to the fundamental is taken into account.

Power factor: relationship between active and apparent power.

PST: (Short term perception). Calculation of flicker over a ten minute cycle.

PLT: (Long term perception). Calculation of flicker over a two-hour cycle.

RMS: Root Mean Square. Efficient value of a current or voltage.

Temporary surge at industrial frequency: temporary increase in the voltage amplitude at a point in the electrical power network above a given threshold.

THD: Total Harmonic Distortion. The rate of total harmonic distortion gives the influence of harmonic components in a signal.

Voltage dip: temporary reduction in the voltage amplitude at a point in the electrical power network below a given threshold.

UNB: Voltage unbalance in a polyphased electric power network; state in which the RMS voltages between conductors and/or the phase differences between successive conductors are not all equal.

Watt: unit of measurement for power (W symbol).
