Simulations
Power Reversal
Verify the Power Quality instrument connected to the simulator is programmed to
record power in a 4-wire wye 3-wattmeter configuration.
Method # 1 Real Time Demand DVM Screen
1. Verify the controls are set to their initial settings.
2. View the real time demand (DVM screen) and note the KW is positive.
3. Set the Power Direction switch on the PQ Simulator to Sink.
4. The KW now reads negative. This indicates a reversal of power.
NOTE: The current vectors are now 180
°
out of phase with the voltage. Current
vectors should never exceed 90
°
of the voltage. If the current does exceed
90
°
of the voltage angle then this indicates a reverse power flow.
