PM-8000 meter

[shawn.janke]

I'm a switchgear FSE and saw an issue today I've never seen before. Our PM8000 meter reads voltage and current correctly on those screens if you select them. Then, going to the power screen, The meter is not calculating a power summary in KW. Most times it sits at zero.

This is the second meter we've tried.

Hi @shawn.janke 

Even if current and voltage appear correct on their respective screens, incorrect Phase Order, Polarity, Scaling or Wiring could cause real power (kW) to calculate as zero. Please double-check:
CT polarity and phase alignment and order
Correct Wiring PM8000 Installation Guide

Whether the meter' Volts Mode is set to Wye or Delta correctly

Another setting to check is the scaled revenue parameters. Will require connecting to the meter with software, either ION Setup or Power monitoring expert. If the scaled revenue parameter is false, check the output of other external Boolean modules, if all modules are false, you will want to paste the template on the meter again. Note that template pastes will remove all logged data.

Sorry Scaled revenue parameters are for the ION7400 and ION9000 meters. May still be good to confirm readings on the meter with software. Would be helpful to read the phasor diagram to see if possible voltages and currents have a phase misalignment.
