(a) A 50 Hz 3 phase alternator with grounded neutral has an inductance of 1.6 mH per phase and is connected to the bus bars through a circuit breaker. The capacitance to the earth of the circuit between the alternator and the circuit breaker is $0.0032 \mu \mathrm{~F}$ per phase. Due to a short on the bus bars, the circuit breaker openswhen the rms value of the current is $8,000 \mathrm{~A}$. determine
Explanation
The frequency of oscillation is an important parameter in determining the behavior of the circuit during a fault. It is calculated using the formula f = 1 / (2π√(LC)), where L is the inductance and C is the capacitance.
