Measuring Accuracy
7.3.8.1 Accuracy Test, Wye Voltages
1. Connect the current sources to the IA, IB, and
IC current inputs (5 A or 1 A, as indicated by
the ITAP setting). Connect the voltage
sources to the VA, VB, and VC inputs in wye
configuration (refer to Figure 7.3, page 103).
2. Using the front-panel Set Relay\Relay
Elements\General Data function or serial port
SHOW command, note the CTR, PTR, and
PHROT settings.
3. Referring to step Table 7.12, set the current
and voltage source magnitudes. The phase
angles you should apply depend on the
PHROT setting. Use the front-panel Meter
Values\Instantaneous Meter function to verify
the relay measurements.
