PERCENTAGE BIASED GENERATOR DIFFERENTIAL RELAY

PERCENTAGE BIASED GENERATOR DIFFERENTIAL RELAY .
Three‐phase percentage biased differential protection relay for generators and rotating machines, with stator earth fault or restricted earth fault element. Measurement of the System‐frequency differential current with DC offset and harmonic components rejection • Phase Differential protection
• Dual slope programmable percentage bias curve
•Earth Fault or Restricted Earth Fault protection
• Harmonic Restraint
• Phase Overcurrent protection
• Breaker Failure protection
• Fn = System frequency : (50 ‐ 60)Hz
• In = Rated primary current of phase
