a
P taps are used with E taps only on regulators where an internal potential transformer is used in conjunction with the
control winding to provide voltage supplies to the control. See nameplate for verification of this type of control supply.
b
Test terminal voltage and overall potential ratio may vary slightly from one regulator to another. See the regulator
nameplate for determining the exact values.
