7.2.1
PHASE CURRENT ACCURACY TEST
The SR469 specification for phase current accuracy is
±
0.5% of 2xCT when the injected current is < 2xCT. Perform the steps below to verify
accuracy.
1.
Alter the following setpoint:
SETPOINT S2:SYSTEM SETUP\CURRENT SENSING\PHASE CT PRIMARY: 1000A
2.
Measured values should be
±
10A. Inject the values shown in the table below and verify accuracy of the measured values. View the
measured values in:

VOLTAGE INPUT ACCURACY TEST
The SR469 specification for voltage input accuracy is
±
0.5% of full scale(273V). Perform the steps below to verify accuracy.
1.
Alter the following setpoints:
SETPOINT S2:SYSTEM SETUP\VOLTAGE SENSING\VT CONNECTION TYPE: Wye
SETPOINT S2:SYSTEM SETUP\VOLTAGE SENSING\VOLTAGE TRANSFORMER RATIO: 10.00:1
2.
Measured values should be
±
13.65V. Apply the voltage values shown in the table and verify accuracy of the measured values. View the
