The O.C of a 5 kVA 200/400 V transformer. In the test, 72 W of power was used, supplying 200 V to the transformer. S.C. In the test, full load current was passed through the secondary supplying 8 V to the primary and taken from a power supply of 80 W. Find the full load efficiency at a power factor of 0.8.
A transformer supplies power to a feeder that has five customers. Daily maximum demands for these customers are 150 kW,
70 kW, 120 kW, 60 kW, and 200 kW. The maximum demand on the feeder is 150kW.
The coincident factor of the feeder is
The primary of a current transformer takes 1 A at a power factor of 0.4 when it is connected across a 200-V, 50Hz supply and the secondary is on open circuit. The number of turns on the primary is twice that on the secondary. A load taking 50 A at a lagging power factor of 0.8 is now connected across the secondary. What is now the value of primary current?
