Question

Q A 50 Hz, 13.6kv, 3-phase arternator with grounded neutral has
inductance of 12 mH per phase and is connected to busbar 16]
through a circuit breaker. The capacitance to earth between the
alternator and the location of circuit breaker is o.03pF per phase.
Neglect the resistance of the alternator. Determine the following:
i) Maximum value of re-striking voltag. ."ro". the contacts
of circuit breaker.
i1) Frequency of transient oscillations
iii) Maximum value of RRRV
ir') Average RRRV upto the first peak of transient
oscillations.
