The Device is self-excited shunt , double bridges and double Digital voltage controllers (DVC) system, It is equipped with hi-performance touch screen。 It is suit for (<=100MW) hydraulic generator and turbo-generator, The Device is suit for single unit operated generator as well as interconnected generator
Main circuit: It is a self-excited shunt system, double bridges
◆ Double Digital voltage controllers
◆ Excitation power: fed from the Generator through rectifier transformer
◆ De-excitation method:
■ Inverting de-excitation
■ Switch off field breaker
■ Non-linear zno resistance is used for De-excitation
◆ Initiating excitation is from generator
