A single-phase step-down transformer is rated 15 MVA, 66 kV/11.5 With the 11.5 winding short-circuited, rated current flows when the voltages applied to the primary is 5.5 kV. The power input is read as 100 kW. Determine Req1 and Xeq1 in ohms referred to the high-voltage winding.

Answer rating: 100% (QA)

Short circuit test is conducted on the high voltage side of the transformer This is because high v... View the full answer
