Question

Q4: A 50 Hz, 11KV, 3-ph, alternator with earthed neutral has a reactance of 5 Ω\ ph and is connected to bus bar through a C.B. The distributed capacitance up to C.B between phase and neutral is 0.01μF, determine: 1-the recovery voltage across the contacts of the breaker, 2-the frequency of oscillation, 3- The restriking voltage across the contacts of the breaker, 4-the average rate of rise of restriking voltage up to the first peak, 5- the time to reach the peak restriking voltage, 6- the value of resistance to be used across the contacts of C.B. to eliminate the restriking voltage, and 7- the value of inductance and capacitance of this system
