UNIT-IMR Insulation monitoring relay

Applicability

  • For monitoring the insulation resistance of unearthed control circuits.
  • Intended for the use in secondary 6-110 kV schemes with AC or DC power system.

Functionality


  • Provides monitoring of current leakage in AC/DC circuits.
  • Provides integrity monitoring of circuits for gas-actuated protective device, auxiliary circuits of busbar protection logical schemes or CBFP circuits. Rated control supply voltage 220 V AC/DC.

Advantages


  • Range of adjustment: 50-1050 µA, with 50 µA step.
  • Precise adjustment by front-face operating controls .
  • Blocking the trip signal, when the current of monitored circuit is more than 2 mA.
  • Output relay has a normally-closed and normally-opened contacts
