A trip backup feature is also available as part of this function, used to issue a second trip if the fault is not cleared within a given time delay. The backup feature can also be assigned to an auxiliary contact for annunciation or remote tripping of upstream protection devices

 

 

Ground Fault This function is designed to protect motors against phase to ground faults. There are two dedicated ground current inputs in the relay, which support the following types of ground current detection. • Core balance (Zero sequence) current transformer. • Core balance (Zero sequence) 50:0.025 A (sensitive) current transformer. • Residual connection of phase current transformers. The function is equipped with an overreach filter, which removes the DC component from the asymmetrical current present at the moment a fault occurs, or a motor starts. Two pickup levels ( trip and alarm) with individual time delays are available for ground fault detection. A trip Backup feature is also available as part of this function. The operational principal of Ground Fault Trip Backup is the same as of Short Circuit Trip Backup
