7.3.2 POWER MEASUREMENT TEST
The SR469 specification for reactive and apparent power is ± 1% of √3x2xCTxVTxVT full scale @ Iavg <2xCT. Perform the steps below to
verify accuracy.
1. Alter the following setpoints:
SETPOINT S2:SYSTEM SETUP\CURRENT SENSING\PHASE CT PRIMARY: 1000
SETPOINT S2:SYSTEM SETUP\VOLTAGE SENSING\VT CONNECTION TYPE: Wye
SETPOINT S2:SYSTEM SETUP\VOLTAGE SENSING\VOLTAGE TRANSFORMER RATIO: 10.00:1
2. Inject current and apply voltage as per the table below. Verify accuracy of the measured values. View the measured values in:
