Last Answer : Primary side is low voltage side and secondary side is high voltage side.
Description : During open circuit test of a transformer?
Last Answer : During open circuit test of a transformer primary is supplied rated voltage.
Last Answer : Low voltage side is short circuited.
Description : Explain the open delta (delta-delta) test on transformer.
Last Answer : Primary is high voltage side and Secondary is low Voltage side.
Description : Explain the procedure to perform Short Circuit test on single phase transformer with circuit diagram.
Last Answer : In short circuit test of transformer the low voltage side is short circuited . On high voltage side the voltmeter is connected in parallel and ammeter in series and also a wattmeter is ... circuit test is done for determining impedance and losses. In this test iron losses is neglected.
Description : A d.c. source has an open circuit voltage of 30 V and an internal resistance of 1.5 Ohm. A resistive load is connected to the source. Maximum power dissipated in the load is (A) 300 W (B) 150 W (C) 45 W (D) 20 W
Last Answer : A d.c. source has an open circuit voltage of 30 V and an internal resistance of 1.5 Ohm. A resistive load is connected to the source. Maximum power dissipated in the load is 150 W
Description : An open-circuit test on a transformer is conducted primarily to measure?
Last Answer : The open-circuit test in a transformer is used to measure
Description : A no-load test is performed on a transformer to determine?
Last Answer : A no-load test is performed on a transformer to determine magnetizing current and loss.
Description : Describe the difference between an open circuit and a short circuit.
Last Answer : Open circuit means the wire is cut meaning power will not flow and close circuit means wire is not cut and hence power will flow.Short circuit is the same as close circuit
