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 used.
--------------------------------------------------------------------------------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 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 optional.
USER INTERFACE 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.
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. OTHER INSTRUMENT SETUP 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.
REAL TIME METER MODES 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.
Harmonics 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.
STORED DATA FUNCTIONS and DISPLAYS 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. Events An event occurs when a programmed threshold limit is crossed.
Waveforms from transient event capture Detailed information of transient event capture 24
List of events with characteristics 25
REPORTS 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 EN50160 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.
ANNUNCIATOR 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 parameter. --------------------------------------------------------------------------------SETUPS Setup is a configuration of parameter thresholds that control the data recorded by PX5.
MEASUREMENT CONNECTIONS 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 current. AUTOMATIC SETUP Automatic Setup is a one-stop process using pre-defined values to set the unit automatically.
MONITORING MENU Once the setup (either stored, automatic or wizard) has been completed, the user can start monitoring instantly or monitor for a fixed period of time.
WIZARD SETUP 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.
Includes automatic detection and comparison of wiring versus selected configuration 31
MONITORING MODES 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).
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.
EVENT CAPTURE and JOURNAL SETTINGS 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 cross trigger matrix determines which channels are saved when a given channel determines that an event has occurred. SITE NAME and MEMORY CARD SETUP 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.
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 Set Scale factors if working with the secondary of PTs or CTs. If your Probe is in the list and selected, Amps Scale Factor should be 1 if not connected to a secondary of another CT.
Memory Card Name your survey. The Site Name will be your data file name. Format your memory card as long as other data files are saved on your PC. Finish then Start Now. Example of Energy/Demand setup using the Wizard Same as previous, except: Monitoring Mode Select Long Term Timed Advanced Options Select Journal Limits, then Disable ALL. Note that this will disable alarming functions on the annunicator panel status report. Activate only those that you specifically need.
