Accumetrics’ Earth Fault Resistance Monitor, Static Rotor Exciter Ground Fault Detector, Rotor Health Monitor, and Ground Detection System all offer superior ground fault protection of motors and generators. Our systems monitor for insulation faults on the field windings of generators and synchronous motors with brushless exciters. They employ advanced wireless techniques to transmit measurement data from the rotor to a stationary receiver unit.
Accumetrics’ rotor ground fault detection systems are in a class of their own. They provide immediate notification of field ground faults, reducing the risk of prolonged and costly unscheduled outages. Learn more about Rotor Ground Fault Monitoring in this demonstration video.
