A large transformer operating at no-load draws an exciting current of 5 A when the primary is connected to a 240 V, 50 Hz source (HELP)
Question 1: A large transformer operating at no-load draws an exciting current of 5 A
when the primary is connected to a 240 V, 50 Hz source. From wattmeter test
it is known that the iron losses are equal to 300 W. At short circuit the voltage applied is 24 Volts , the short-circuit current is 35 Amperes, the power meter reads 400 W.
Calculate:
i) The reactive power absorbed by the core;
ii) The value of Rc and Xm of the magnetising branch;
iii) The value of Ic and Im ;and
iv) The series impedance of the transformer.
