The correct phasor should be around 120°, not 300° where the phasor currently is. Since the phasor is approximately 180°... -
Page 88: Phase Voltage Deviation Check
Operation: CP1SD/T/L Version Phase Voltage Deviation Check Once every five seconds, the phase A voltage is combined with a user-defined percentage tolerance (x) to determine the upper and lower bounds of the acceptable range for the other voltages. The range of values for the percent tolerance is 1 to 25. For Diagnostic #2 to pass, the following equations must be satisfied: ≤... -

Operation: CP1SD/T/L Version SiteScan Diagnostic #4 The purpose of this diagnostic is to verify that the current elements are sensing and receiving the correct current for each phase. It is basically a power factor check diagnostic. This diagnostic check may indicate one or more of the following problems: Poor load power factor conditions Poor system conditions Malfunctioning system equipment... -
Page 92: Figure 32: Envelope Example
Operation: CP1SD/T/L Version An example would be if a typical diagram has the C phase current angle at 240° and the user has programmed an acceptable envelope of ±45° around that phasor, then the actual current phasor must be between 195° to 285° from VA for the diagnostic to pass that check. The system will check each current phasor in a similar fashion. -
Page 93: Sitescan Diagnostic #5
Operation: CP1SD/T/L Version The next step is to graphically plot the above information into a phasor diagram as shown in the figure below. Figure 33: Phasor Diagram By comparing the phasor diagram drawn from the information found in the snapshot versus the typical phasor diagram, it becomes clear that the C phase current is out of the user- defined envelope. -
Page 94: Current Waveform Distortion Check
Operation: CP1SD/T/L Version Current Waveform Distortion Check Diagnostic #5 detects DC on a per-phase basis using what is know as a comb filter method. Rectified loads produce even harmonics which are typically in phase with the voltage signal. The algorithm works by summing current samples, which occur 90° after every zero crossing of the voltage waveform. -

Page 96: Load Indication/Direction Annunciator
Operation: CP1SD/T/L Version Load Indication/Direction Annunciator The CENTRON Polyphase meter is equipped with a Liquid Crystal Display (LCD) load emulation indicator. The Load Emulator follows the Infrared Test LED. For each pulse of the Test LED, the Load Emulator increments one segment. The operation of the Load Emulator depends on the quantity being pulsed. -
Page 97: Nominal Voltage Indication Annunciator
Operation: CP1SD/T/L Version Nominal Voltage Indication Annunciator The CENTRON Polyphase meter is equipped with a nominal voltage indication annunciator. This annunciator indicates the voltage value to which the nominal voltage is nearest. Nominal voltage indication values are 120, 240, 277, and 480. Test Mode Annunciator The CENTRON Polyphase meter is equipped with a Test Mode LCD annunciator. -
Page 98: Testing Using The Load Indication Annunciator
If accuracy or repeatability is poor, the Kh may be incorrect or the “settling time” in the test bench must be adjusted. (Itron recommends a 4–5 second settling time.) Testing Using the Load Indication Annunciator The CENTRON Polyphase meter is capable of visually being tested by using the load emulation annunciator shown in Load Indication/Direction Annunciator. -
Page 99: Recommendations
Operation: CP1SD/T/L Version The current ramps (directly or through zero) to the LL current level at unity power factor. A pulse from the meter starts the LL test and another pulse ends it. Most test boards use jogging (slewing) immediately following a FL or PF test to shorten the time required for the next test to start. -
Page 100: Demand Testing
Operation: CP1SD/T/L Version Solution 3 Install the latest test board software revision. A test board ideally should recognize no new test pulses after the completion of a test until jogging, ramping, and settling time have all transpired. Settling time should be programmed for three to six seconds. There is nothing to be gained by using settling times greater than six seconds. -
