Connect T4, T5, and T6 Neutral The following information concerns the sensing connections for the voltage regulator:
On medium voltage generators, sensing isolation transformers are used. The line lead's voltage connects to one side of the sensing isolation transformer. The voltage regulator connects to the other side of the sensing isolation transformers.
On generators up to 600 volts, the leads for the regulator have a direct connection to the generator line leads. The leads for the regulator supply sensing voltage to the regulator. Twelve Lead Wye (Star) Connection (Series Wye)
