Converts the AC supply to the voltage required by excitation equipment, with winding isolation.

Isolated Excitation Supply

Cast-resin windings provide thermal and mechanical strength for short-circuit duty.

Short-circuit Withstand

Vacuum casting supports low partial discharge and insulation reliability.

Vacuum-cast Insulation

Winding design addresses harmonic losses associated with excitation rectifier loads.

Harmonic Load Design

Winding temperature sensors support central-system monitoring and overtemperature alarms.

Temperature Monitoring

Low core flux density and magnetostriction control help reduce operating noise.

Low-noise Core Design
