1. Apply the following voltages to the relay through the rear terminals A2-A3,
A4-A5, A6-A7. THE ANGLES ARE LAGGING!
VA (A2-A3) = 67
0°
VB (A4-A5) = 67
120°
VC (A6-A7) = 67
240°
2. Adjust the fault current argument in accordance with table MHOZIØØG-5IN or
table MHOZ1ØØG-1IN, according to the rated current: (it is left to the user's
discretion to select the characteristic point(s) to check).
Note: The angle
between the two fault currents must be 180º
3. Set the fault current (IA, IB, or IC according to the phase in fault) to 10 A for IN =
5 and 2 A for IN = 1 and the rest of the currents to zero.
4. Simultaneously reduce the voltage of both phases gradually and check that the
relay trips when the voltage is within the limits listed in tables MHOZ1ØØ-5IN or
MHOZ1ØØ-1IN.
5. Reduce the fault currents to zero.
6. Repeat the tests for faults between phases BG and CG.
