Numerical Biased Differential Protection Relay Type : MIB 202
     
   

 

MIB 202 works on the current differential principle and takes the current inputs from both the ends of two winding power transformer and auto transformer. 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
