Numerical Single Function Relays : Genesis->
Numerical Biased Differential Protection Relay Type : MIB 202
     
   

 

MIB 202 takes the current inputs from both the ends of two winding power transormer and auto transformer, it is working on current differential principle. It provides stability against magnetic inrush conditions. Load/through fault stability is achieved through bias setting provided in the relay. It operates only for internal faults.

Application

  • Two winding power transformers
  • Auto transformers
  • Biased differential protection for generators
