The AVR has the faclity compatible with droop CT connection,to allow parallel running with other similarly equipped generators. SX440 is a two phase sensed Automatic Voltage Regulator(AVR) and compatible withms part of the exciation system compatible with a brush-less generator. The AVR senses the voltage in the main generator winding and control the power fed to the stator and hance the main to maintain the generator output voltage within the specified limits, compensating compatible with load sprrd,temperature and power factor of the generator.
