A synchronous generator is feeding its rated power of 250 MW to a large 60 Hz network over a double circuit transmission The maximum steady state power that can be transmitted over the line with both circuits in service is 500 MW and is 350 MW with any one out of service.

A solid three-phase fault occurring at the network-end of one of the lines causes it to trip. If inertia constant is H = 3.5 s, calculate the critical clearing angle and critical clearing time in which the circuit breakers must trip so that synchronism is preserved.
