Working Mechanism

  • When an abnormal condition or fault is detected, the relay initiates a trip signal to disconnect the transformer from the power system, protecting it from damage & ensuring safe and reliable operation.

Features

  • Eaton ETR-4000 Series transformer relays have 14 programmable LEDs for quick & easy display of operating status.
  • Their unrestrained differential element offers quick tripping to prevent catastrophic damage and reduce risks to the rest of the power system.
  • Their front panel LCD with background illumination allows for wide-angle viewing in all light conditions.
  • These transformer relays have zone selective interlocking to improve coordination and tripping time.
  • Their maintenance mode provides a simple and reliable method to reduce fault-clearing time and lower incident energy levels at energised panels.
