6.10.1 Test Description
Tests performed:
1.
Operate voltage: determines the pick up threshold of a definite time over voltage element.
2.
Operate time: determines the operate time with 115% of nominal operate voltage.
Input Parameters:
1.
Relay Id:
Six digit numeric identifier for relay.
2.
Voperate:
The expected operate voltage in [Volts]. Range 1.0 – 150.0 V.
3.
t
(op)
:
The expected operate time in [sec] at 115% of Voperate. Range 0.001 – 15.0 s.
4.
Vprefault:
The desired prefault voltage in [Volts], Range 0.0 – 150.0 V
Output Results:
1.
Operate voltage test: Measured operate voltage [V]
2.
Operate time test:
Measured operate time [sec]

Instantaneous Over Voltage (59)
The following example demonstrates the steps required to test the pickup and operate time for a definite
time over voltage relay. The relay settings are: Voperate = 130 V, operate time = 32ms.
