Consider a simple power system: two generators (20MVA each at 13.2kV) running in parallel via a combined generator step-up transformer (rated at 30/33.3/36.7 MVA: ONAN/ONAF/ONAF cooling, 13.2 (Delta)/115 (Solidly Grounded Wye) kV). The sub-transmission line is 10.0mi long and rated at 115kV. Estimate (write the assumptions) the 3-phase bolted fault current at the end of the 115kV line. 20 MVA 13-2 kv 30/33-3/36,7 MVA 13.2- 115 kV t0 mi Fault
