Determine efficiency on diffrent load cycle, Electrical Engineering

Assignment Help:

Q. A 75-kVA transformer has an iron loss of 1 kW and a full-load copper loss of 1 kW. If the transformer operates on the following load cycle, determine the all-day efficiency:

8 hours full load at unity power factor

8 hours no load

8 hours one-half full load at unity power factor
