Question

(5) The no-load current of a transformer is 5A at 0.25 power factor (lagging). when
supplied at 230 volts, 50 Hz supply. The number of turns on primary winding is 200.
Calculate
The maximum value of flux in the core;
Core loss with magnetising current;
Secondary winding turns ir K is 1:4
Shunt parameters
Draw the phasor diagram

Answer 1

Answer:

The transformers “no-load” current taken from the supply is 3 Amps at a power factor of 0.2 laggingNo-load current of a transformer

The phasor sum of the magnetizing current (Im) and the loss component of current (I1) ; Im is calculated using the MMF/m required for the core and yoke and their respective length of flux path. ...

The no-load current I0 is the vectorial sum of the magnetizing current Im and core loss or working component current Ic.The r.m.s. value of the current flowing through a line terminal of a winding when rated voltage (tapping voltage) is applied at rated frequency, meantime the other winding or windings being open circuited.
