Question

(a) Derive necessary equations to find fault current and interconnection of sequence networks for line to ground fault at the terminals of the alternator.

(b) Estimated short circuit $\text{MVA}$ at the bus bars of a generating station $1000\text{ MVA}$ and other station is $666\text{ MVA}$. The generated voltage of each station is $11\text{ KV}$. Determine the possible short circuit $\text{MVA}$ at each station when they are linked by an interconnected cable with a reactance of $0.5\text{ ohm}$.
