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 voltage inputs in delta
configuration (refer to Figure 7.4, page 104).
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 Figure 7.4, page 104, 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.
