Question

Using a value of SBASE = 100MVA, Using the Per Unit method and symmetrical components calculate expected fault current at the load bus shorted for a Line to Ground fault. All generators are operating at rated voltage. Assume all transformers are delta on the primary and grounded Y on the secondary.
