GENERATOR MONITORING CIRCUIT A circuit for monitoring the output of a power generator is disclosed. The circuit utilizes a current sensing transformer for each of the three phases of the power generator. The current is sensed, and after compensation for phase angle, is summed and provided to a bridge network. A difference amplifier connected to the bridge network produces a difference signal representative of the voltage across the bridge network. The difference signal is supplied to a speed governor. By interconnecting additional circuits, a plurality of generators may be regulated to maintain a substantially equal load on each. The use of a difference amplifier provides the capability of intermixing speed governors having different D.C. reference levels. A low pass filter network for high frequency noise rejection is provided. |
