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) Brushless excitation of hydraulic generator and turbo-generator, The Device is suit for single unit operated generator as well as

 

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

◆ Initiating excitation is from generator residual voltage and DC control supply
