Performing a Load Tap Changer / Voltage Regulator Resistance Test
The Load Tap Changer/Voltage Regulator Resistance Test can be used to conveniently measure
the resistance at each tap position. Once the number of taps has been entered, the WRM will
request the user to set the tap position, starting with the lower taps, then to neutral, and then
to the raise taps. At each tap position, the resistance is measured, displayed on the LCD screen,
and stored. The WRM then instructs the user to change to the next tap position and repeat the
testing process.
