All Energy Platform functions described below are operable using a color LCD touch screen technology. Users may use a finger and/or a PDA stylus to app ly p res sur e t o t he LCD screen to result in touch screen recognition. The touch screen display is also workable with line man gl ove s on. T ouc h screen buttons will appear in reverse-video to show visual feedback of contact along with audi ble fe edback. 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 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 dis play are user pr ogrammable. Scope mode al so provi des a te xtual 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 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
Event
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.
Energy Platform features an Event List screen which shows a summary of all captured events in the order that they occurred. An event occurs when a programmed threshold limit is crossed. Energy Plat form is able to record three typ es of events namely sag, swell or aggregate snapshot.

The Energy Platform can monitor the following power configurations:
• Single Phase • 3 Phase 2-Watt Meter Delta
• Split Phase • 2 1/2 Element without V
• 3 Phase Wye • 2 1/2 Element without V
B C
While monitoring any of the above configurations, the Energy Platform can also be connected to monitor neutral to ground voltage and neutral or ground current, where applicable.
Setup is a configuration of parameter thresholds that control the data recorded by the Energy Plat form. Users ma y perform instrument setup in three ways: v ia Automatic Setup which utilizes au to- configured settings and all ows us er s 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 setup which allows users to modify trigger parameters and intervals or tweak threshold settings under the Advanced Options.
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
Energy Platfor m featu re s a summar y repor t for Demand and Energy parameters in easy to read format. The data is displayed via the report panels. The panel is color coded such that green indicates the parameter is within limits, yellow means parameter is moderately out of limits, while red means parameter severely exceeds the monitoring limits.
Energy Platform supports the use of Compact Flash data card with part number CFDATA-DB. The user replaceable data card is used as primary storage for data. Data monitoring CANNOT proceed without the data card. The Energy Platform is designed to accommodate the Compact Flash card in its native format, and does not require the use of a PC card adapter.

Section C
Harmonics
Harmonics display
The Energy Platform 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 frequen cies. The IEC 61000-4 -7 Sta ndard dicta tes that harmon ic analysis is done using a synchronous window of 10 cycles for 50 Hz, or 12 cycles for 60 Hz. This results in b ins whi ch are nominal ly 5 Hz wide. The actua l widt h of t he bins is equal to the actual freque ncy 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 but tons to dis play the next Channe l (Channe ls 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 numbe r or ran ge of harmonic frequencies to trend and vi ew 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.
Harmon i c Graph Users can choose the unit of measure by which harmonic data is calculated and graphed, based on a Per centage of the fundamental va lue or in Engineering units (volts and amps). Frequency co mponen ts of harmonic graph s can b e disp lay ed either in Her tz or in Harmonic Number. The graphs can be zoomed and rescaled.
: Harmonics are measured in ac cor dance with IEC 61000-4-7 Class 1.
Harmon i c L i st measured values: f requency a nd harmonic number; magn itude in Engineeri ng units and percent of fundamental ; ph ase in degrees (for harmonics o nly). This list is displ ayed in order of ascending frequency, and can also be sorted in order of descending magnitude.

Harmonic/ Interharmonic data plots
The voltage and current harmonics and/or interharmonics for each phase channel can be trended using the Options but to n. The properties specified under Harmoni c Op ti ons 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.

Scale Factor Setup

Scale Factor Setup
What is a scale factor?
When to use
Non-Dranetz equipment
Sample calculation
A scale factor is the ra tio of the i nput to outp ut for a pa rticula r current transfor mer (CT) or potential transfor mer (PT). A scal e f act or is e ntered in the Energy Platfor m 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.
Scale factors must be entered for the following conditions:
• A Dranetz
• The current connections are made using a Dranetz
• The voltage connections are made using a PT.
Refer to the CT name pla te or to the manu facturer’s literature to deter mine the scale factor.
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:
current probe is connected to a permanently installed CT.
ISO box.
Scale Factor = 1000/5 = 200
5-10
Example of step-up ratio If a potential transformer has a step-up ratio of 1V:10V, therefore:
Scale Factor = 1/10 = 0.1

Frequency synchronization
Frequency tracking
Normal frequency synchronization (sync) of the Energy Platform analog signal processing circuits is controlled by analyzing the external AC voltage signal input on channel A. If sync is lost, then internal sync is automatically selected. The frequency used for internal is entered und er Fr equency on the Nominal Values screen (see page 5-
14).
Typically, external sync on Ch D is specified if it is known that signal on A is 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.
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 thr ough” volta ge change s to keep tra cking the f undamental f requen cy even in the absence of voltage.
Fast mode
: When operating on a l ocal genera to r [Fa st], th e fr equency will v ary mor e as loading changes occur. The Fast mode allows the instrument to follow these changes more closely.
Internal mode
: In cases where no r eference si gnal is ava ilable ( such as DC monit oring),
