Voltage & Current

 From MonitoringVoltage & Current, verify RMS values for both

voltage and current are the expected values.

If incorrect, check the PT/CT ratios as well as the connection of the voltage

and current probes to the device and the power source.

Monitoring/Power

 From MonitoringPower, verify the Active power readings are

positive integers.

If the active power reading in any phase is negative (yellow highlight), then

change the relevant phase from Normal to Reverse in

ConfigurationCurrents or reverse the polarity of the current clamp at

the power source by changing the direction.

Generators commonly display a negative Active power value.
