Static Exciter Rotor Ground Fault Detector | AT-8100

Continuous Monitoring for Brushed Exciters

The Static Exciter Ground Fault Detector Model AT-8100 provides continuous wireless monitoring of insulation fault resistance and field voltage on brushed exciter generator and motor field windings, combining advanced ground fault measurement techniques with the latest innovations in digital telemetry. The system also provides users with condition monitoring data, allowing operators to monitor trends over time in order to make better informed operational and maintenance decisions.

  • Continuous on-line monitoring of faults while rotating or at standstill
  • Trending of fault severity resistance
  • Indication of fault location for ease of diagnosis and repair
  • Ongoing monitoring of field excitation voltage
  • Alarm relay contact outputs for multiple resistance limits
  • Built-in self-diagnostics and malfunction alarm
  • Rotor protection through condition-based maintenance
  • Predictive maintenance for large generators and motors
  • Early warning system of impending failure due to ground faults
