Set the unit as follows:
Ensure that the input configured as 52B (breaker status) is not active, indicating open breaker. If it was, the unit would be
disabled and the relay would not operate.
With the V APP setting entered, the relay calculates the impedance as VI/Ia.
The voltage supervision is enabled, at a level of 70% of the rated voltage:
Supervision V = 70% of Vn = 0.7 x 11000 / 100 √3 = 44 V
