The PowerMonitor 5000 unit provides a means for you to verify proper power monitor connections and diagnose wiring errors. To meter power and energy correctly, voltage and current inputs must be connected to the power circuit with the correct phase rotation and polarity. Indications of wiring errors include the following: • Indication of negative real power (kW) on a load, or indication of positive power on a generator • Power factor outside the range of 45% lagging to 80% leading • Very different power and/or power factor values on different phases Wiring diagnostics operate on command in any wiring mode, and require a level of measured current at least 5% of the nominal metering scale, or 250 mA of CT secondary current. For example, a power monitor with 600:5 CT ratios configured for I1, I2, and I3 requires 30 amps of load current for wiring diagnostics to operate
The PowerMonitor 5000 unit calculates phase angles of voltage and current, and checks these against three distinct ranges of system power factor: • Range 1: lagging 97% to leading 89%. This range is for very high lagging or significantly leading power factors. Examples of loads in this range include data centers, over-excited synchronous motors, and circuits with power factor correction. • Range 2: lagging 85% to leading 98%. This range includes most industrial circuits that range from lagging to slightly leading power factors, including circuits feeding AC variable-frequency drives. • Range 3: lagging 52% to lagging 95%. This range exhibits lower lagging power factors. Examples include lightly-loaded motor circuits and DC SCR drives.
