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 REACTZ2ØG-5IN or
table REACTZ2ØG-1IN, according to the rated current: (it is left to the user's
discretion to select the characteristic point(s) to check).
3. Set the fault current (IA, IB, or IC according to the phase in fault) to 3 A for IN =
5 and 2 A for IN = 1 and the rest of the currents to zero.
4. Reduce the voltage of the phase in fault gradually and check that the relay trips
when the voltage is within the limits listed in tables REACTZ2ØG-5IN or
REACTZ2ØG-1IN.
5. Reduce the fault current to zero.
6. Repeat the tests for faults in phases BG and CG.
