What is kVA?

PI144F Stamford

This clockwise rotation 3-phase alternator delivers 30.3 kVA of standby power and 27.5 kVA of prime power when operating at 50 Hz.

PI144F Alternator

The alternators main stator provides power via the AVR to the exciter stator from its self-exiting system. High-efficiency AVR semi-conductors allow positive build-up from initial low levels of residual voltage.
