Statement and Notices …………………………………
The Dranetz PowerXplorer® PX5, Power Guide 4400, and the Power
Visa are three portable, hand-held, eight-channel power quality
meter/monitors, very similar in operation though the PX5 and 4400 have
some additional parameters not in the Power Visa, and the PX5 has a
high speed sampling board for capturing the details of very fast
transients. The common features are covered in this document, and the
PX5 name will be used to represent all three instruments. These cuttingedge power quality instruments are designed with a color liquid crystal
display (LCD) 1/4 VGA, using touch screen technology. They 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 PQoptimized 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.
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 software applications such
as NodeLink® and DranView®.
Getting Started

1. Voltage and Current Connections – there are four differential
voltage and four differential current channels, which can be wired
to measure a variety of circuit configurations. Use only Dranetz
voltage leads and current probes for proper operation. Do not
exceed marked ratings.
2. Graphic Color LCD with Touch Screen – the color LCD has an
integral touch screen that is used to select functions for setups,
real time meters, and viewing stored data. Either a clean finger
or a PDA-type stylus can be used and the screen should be
calibrated with whichever you are going to use by selecting
Preferences; Display Preferences, then Calibrate Touch screen
when first turned on. Clean only with soft cloth.
3. Field Replaceable Battery Pack – the internal UPS feature
requires that the internal batteries be properly charged and
maintained. If the battery pack is in need of replacement, deenergize the connections and power to the unit before opening
the battery door and replacing the pack only with the Dranetz
battery pack PN# BP-PX5. A spare battery pack may be useful
to have.
4. Memory Card slots for data and firmware updates – the Dranetz
supplied Compact Flash memory cards are used for data
storage, as well as to upload new firmware versions when
available. Use only Dranetz supplied memory cards, as the
speed requirements of the instrument can not be satisfied by
many off-the-shelf memory cards. Do not remove the memory
card while monitoring. Only one slot is active at a time.
5. There are three status LEDs and the ON/OFF switch (push for
on, push for off) are located on the bottom of the instrument. AC

Connecting Voltage Measurement Cables
Measurement cable set
Description: Voltage measurement cables are provided as
standard accessories and are stored in a cable pouch as part of
the measurement cable set, P/N 116042-G3. Each cable set
consists of a cable and alligator clip.
Voltage Rating: Direct connection of all voltage measurement
cables are rated at 600 Vrms max. For measuring voltages
greater than 600 Vrms, potential transformers (PTs) must be
Optional fused voltage adapter
There are two optional fuse accessory kits available for use with
the measurement cables for PX5. One kit (P/N FVA-1) contains
one fused voltage adapter and one measurement connecting
Red cable 50 cm in length. The other kit (P/N FVA-4) contains
four voltage adapters and four measurement connecting cables
50 cm in length (one Red, one Yellow, one Blue, and one Grey).
WARNING: To avoid the risk of electric shock or burns, always
connect the safety (or earth) ground before making any other
WARNING: 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.
WARNING: 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 KLKD0.30
rated 600V AC/DC, 0.3A fast blow.
WARNING: 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

• Single phase
• Split phase
• 3 Phase Delta
• 3 Phase Wye
• 3 Phase 2-Wattmeter Delta
• Generic
• 2 ½ Element without Vb
• 2 ½ Element without Vc
3 Phase Wye and 3 Phase Delta are described in this Quick Reference
version of the User’s Guide. For other configurations, please consult the
complete Users’ Guide, UG-PX5.
3 Phase, Four Wire Wye
Channels A, B, and C are connected to voltage and current
probes. The neutral is connected to common and is the
reference for the three channels. The figure also shows voltage
connection using channel D as a differential input for measuring
neutral to ground voltage. Neutral to ground measurements are
important but optional.
3 Phase (Floating or Grounded) Delta
In this power connection, the PX5 uses voltage channels A, B,
and C as differential inputs with channel A using source voltage
A-B, channel B using B-C, and channel C using C-A as the
reference. Current probes are connected to channels A, B, and
C. Neutral to ground measurements are important but optional.
Split Phase and Open Delta
For either of these two power connections, the PX5 uses only
two voltage channels A and B as differential inputs with channel
A using source voltage A-N or A-C and, channel B using B-N or
B-C. Current probes are connected to channels A and B. Neutral
to ground measurements are important for split phase but
Split Phase (above)
Open Delta (below)
The instrument powers up with the Home Page screen, shown above.
The top portion of the screen is for status information, including:
monitoring status (on, off, or armed); what type of circuit is being
monitored; the memory card status (not inserted or percentage full); the
data file name; the number of waveform cycles saved (indication of event
activity); number of journal records saved (periodic timed storage of
parameters); and, the real time clock display.
The first row of icons are referred to as Real-Time-Meters, showing the
instantaneous values of the parameters. The second row of icons are for
display of stored data, either through trend plots, event waveforms and
rms plots, and reports of either EN50160 data or an annunciator panel of
user selectable parameters and their state (normal, out of limits). Also in
this second row is the icon for setting up instrument parameters, such as
time/date, memory, language, LCD, and touch screen.
In the bottom of the screen is a button for Start menu, which allows for
starting to monitor from either the existing setup, recalling a stored setup
from the memory card, or going through the setup process again, either
in automatic setup mode, or the step-by-step wizard.
Functions, such as the time/date, which language, communication port
setups, and LCD settings can be changed from the Instrument Settings
menu, as well are formatting a memory card. This screen is activated
from the PREFERENCES icon on the Home page.
Scope mode
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
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. User can select
which parameter to show the harmonics for (V,I,W), which channel
(A,B,C,D), zoom in a the 5Hz components, set options such as showing
harmonics and/or interharmonics and displaying in Hz or harmonic
number, scaling to the fundamental or absolute value, and a list of the
harmonic magnitudes and phase angles in tabular fashion.
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.
Users can generate plots for all journalled data combined with min/max
recordings of that parameter. Most journal parameters have multiple
channels to plot.
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
cycles(s) The event data for all of the captured channels can be
displayed in time plots of the rms values or waveforms, event details
such as trigger conditions, characterization of the event according to PQ
standards, and min/max values, or the time-stamped event list.
Trend of rms voltage and current
Waveforms from transient event capture
Detailed information of transient event capture
List of events with characteristics
There are two types of reports – EN50160 for Quality of Supply
reporting, and the Annunciator panel, which the user can select to
display the present state of 4-16 parameters
If a parameter is below the 95% limit for EN50160, then the bar graph
will turn red. Some of the parameters have more detailed information
about them, which can be displayed by pressing on the parameter name.
History of prior measurement weeks can be displayed, along with the
magnitude and duration distribution table (DISDIP), and the min/max
values during monitoring interval.
If the parameter is outside of the normal), it will either turn yellow limits
(low or high) or flashing red (very high or very low) until the user clears
the annunciator to reset them all to green. Pressing the parameter
button itself will show time plots and other detailed information about the
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.
PX5 can monitor the following power configurations:
• Single phase
• Split phase
• 3 Phase Delta
• 3 Phase Wye
• 3 Phase 2-Wattmeter Delta
• Generic
• 2 ½ Element without Vb
• 2 ½ Element without Vc
While monitoring any of the above configurations, the PX5 can also be
connected to monitor neutral to ground voltage and neutral or ground
Automatic Setup is a one-stop process using pre-defined values to set
the unit automatically. Users have the option to view the summary list of
parameter settings, change probe types if current will be monitored,
and/or proceed directly with data monitoring.
Once the setup (either stored, automatic or wizard) has been completed,
the user can start monitoring instantly or monitor for a fixed period of
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. The screens are shown in the sequence
that they appear when in the Wizard Setup.
Current probe types (if used), scale factors (when using additional PTs
and/or CTs), circuit configuration (single phase, wye, delta, etc), and the
nominal voltage, current and frequency tracking range are set up first
before selecting the monitoring mode.
Includes automatic detection and comparison of wiring versus selected
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 re 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
I2t curve of a breaker trip is key to preventative maintenance and
enhanced power system performance. Inrush type 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.
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 longterm 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 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.
Motor Quality: Automatically sets up the parameters that affect the
operation of motors. Motor parameters include True Power Factor,
Horsepower, and Derating Factor, among others.
The transient limits for instantaneous peak, high frequency transient
(PX5 only), waveshape deviation and waveshape rms deviation; rms
variation limits for cycle-to-cycle triggers (high, low, very low), waveform
capture cross-trigger matrix, characterization options, journal limits (very
high, high, low, very low), and journal interval rate can be changed by the
user and saved as a template for future use.
The wizard uses interactive graphical images to show the user what the
present values are and the effect of the proposed changes, as illustrated
The cross trigger matrix determines which channels are saved when a
given channel determines that an event has occurred.
The last step in the setup is to select the name for the data file, as well
as perform any housekeeping functions on the memory card, such as
format a new card or delete old data by reformatting. When multiple
monitoring sessions are performed using the same file name, the
instrument automatically increments and appends a number to the end of
the file name.
Example of Power Quality setup using the Wizard
Current Probe
Select the current probes you are going to use from the list. If you are
using LEMFlex make sure the probe and list match exactly. Full scale
current should not exceed probe rating and nominal current should not
be less than 10% of full scale.
Scale Factors
