The Gas Detector Relay, or GDR™, of Hitachi Energy, provides an early indication of faults in oil-filled conservator-type power transformers.

The GDR™ provides alarms under two types of transformer fault conditions:

  • Faults of an incipient or minor nature resulting in a slow evolution of gas 
  • Faults of a major nature that generate a sudden pressure wave
