Power Tech Generators PTS-30 Operator's Manual page 175

A Generators use the droop method. The method of kVAr sharing is to create a generator voltage
characteristic, which falls with decreasing power factor (increasing kVAr). This is achieved with a current
transformer (C.T.), which provides a signal dependent on current phase angle (i.e. power factor) to the
AVR.
If parallel operation is envisioned for your generator, please contact the factory at time of ordering, so that
the proper accessories can be provided.
