Product Description
Micom P721 High Impedance Differential Protection Relays

High Impedance Differential Protection Relays

MiCOM P72x high impedance differential protection seriesprovides high impedance differential protection for generators, reactors, motorand busbar applications. Models available: MiCOM P721, MiCOM P723

Features

MiCOM P721 also offers the same applicationbenefits as traditional high impedance electromechanical protection schemes, itcombines the added benefits of numerical technology to provide advancedcommunications, event records, fault records, disturbance records and ancillaryprotection features.

Combined with the MiCOM P79x, a standalone metrosil and resistor unit, it provides simplified scheme engineering for single or three-phase differential applications.

Standard Manufacturers Warranty: 2 years

Benefits

Numerical High Impedance Relay

  • Simple scheme engineering
  • Reliable algorithm - stable for through fault and fast trip for internal fault
  • Supervision functions included in the same protection box
  • Set by current or voltage
  • Numerical relay features

Applications

P72x offers reliable protection for busbars, transformerswindings, generators, reactors and motors. P721 is suitable for restrictedearth fault (REF) or balanced earth fault (BER) applications. P723 is suitablefor busbar and machine phase differential protection.
