3.3.2. Performing a Voltage Regulator Test
The Voltage Regulator Test verifies that a regulating switch in a primary voltage tap regulator
changes contacts through its selection range without a break in the circuit. This test is
important because in actual use, any break in the current in a regulating tap switch generates
large reactive voltage spikes that are hazardous and may exceed the switch’s voltage ratings,
thus causing irreparable damage. By connecting the WRM-10’s continuity test input across the
switching input and running the regulator switch through all the contacts in its range, any break
in continuity caused by faulty tap switching can be detected.
To perform a voltage regulator test:
