The line current provided by the transformer secondary is 30 amps.
The circuit shown in the image is a three-phase transformer with a delta-connected primary and a star-connected secondary. The primary voltage is Ep and the secondary voltage is EL. The primary and secondary currents are Ip and IL, respectively. The impedance of the load is Z.
The line current provided by the transformer secondary is IL. The relationship between the line current and the phase current in a delta-connected transformer is:
IL = √3 * Ip
Therefore, we can calculate the line current as follows:
IL = √3 * Ep / Z
Substituting the values given in the image, we get:
IL = √3 * 220 / 2.77 = 30 amps
Question:-
In the circuit as shown below. what is the line current provided by the transformer secondary?
