Determine resistance per pulse representing the core loss and the magnetizing reactance per pulse of the core.

The result of no-load test on a 3 phase Y-connected induction motor are as follows:

line to line voltage = 400 V
Input power = 1770 W
Input current = 18.5 A
Friction and windage loss = 600 W

Determine
(a) resistance per pulse representing the core loss and
(b) the magnetizing reactance per pulse of the core.
