3. Connect the relay as shown in Figure 5–1: PHASE-TO-PHASE TEST CONNECTIONS on page 5–7 for
the appropriate phases under test. Set the relay to test mode 14 (Any Zone 1 Phase). The LUI displays:
ANY Z1 PHASE ON
4. Set the voltage inputs to the following values:
VA: 67 volts rms ∠0°,
VB: 67 volts rms ∠–120°,
VC: 67 volts rms ∠+120°.
5. Set the fault current phase angle to ∠ I
out of phase with the line to which it is shorted.
6. Set the fault current to I
check that the A1 contact closes when the voltages are within 7% of V
7. Repeat the test for phase BC and CA faults.
