A single-phase, 2,959 VA, 2200/220 transformer has the following open circuit and short circuit test data: Open-circuit test: 433 watts, while the test is carried out at rated voltage. Short circuit test: 434 watt, while the test is carried out at rated current. for a unity power factor, calculate the PERCENT transformer efficiency at 2% of the rated load
