Excitation & Generator Controls repair

Field exciters, AVRs, generator controllers and engine control units. Excitation systems and generator controls regulate voltage and protect the generator, so faults show up as unstable voltage, field failures or tripping on load. AVR boards, thyristor bridges, controllers and engine control units can be repaired and tested.
