Performing a Transient Test
The transient test verifies that a regulating switch in a Voltage Regulator or Load Tap Changer
changes contacts through its selection range without a break in the circuit. This is an important
test because in actual use, any break in current in a regulating tap switch generates large
reactive voltage spikes that are hazardous and exceeds the switch’s voltage ratings, thus
causing irreparable damage.
By connecting the WRM continuity test input across the switching input and running the
regulator switch through all the contacts in its range, any breaks in continuity caused by faulty
tap switching can be detected. Please note that the transient test is applicable for the V1
channel only.
