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
Define Time and Shift Invariant? Time and shift invariant means that the system characteristics and shift do not change with time, i.e. the system output is independent of the
