Relay protection out-of-step tripping

Performance of out-of-step tripping protection

Out-of-step or loss of synchronism condition occurs when one or a number of generators in the system fail to maintain synchronism with the rest of generators. OST protection is achieved by installing

Relay Performance During Major System Disturbances

An unstable power swing results in a generator or group of generators experiencing pole slipping or loss-of-synchronism for which some corrective action must be taken. Out-of-step is the same as an
