9 COMMISSIONING
Set the relay as follows
Apply voltage as indicated on the table under the overvoltage setting level and verify that the relay does not trip.
Verify that the relay trips for the set voltage (with an admissible error of 5%).
ELEMENTS INPUT
59NH/59NL VX
This element can also be tested by applying only phase voltages. For this purpose, it is necessary to set Auxiliary Voltage =
VX. In this condition, Vn voltage is calculated as a sum of the phase voltages.
