GATE Electrical 2013 | Question: 9
A single-phase transformer has no-load loss of $64W$,as obtained from an open-circuit test.when a short-circuit test is performed on it with $90\%$ of the rated current flowing in its both $LV$ and $HV$ winding,the measured loss is $81W$.The transformer has maximum ... $80.0\: \%$ of the rated current. $88.8 \:\%$ of the rated current.

GATE Electrical 2014 Set 2 | Question: 13
A three-phase, $4$-pole, self excited induction generator is feeding power to a load at a frequency $f_1$. If the load is partially removed, the frequency becomes $f_2$. If the speed of the generator is maintained at $1500$ $rpm$ ... $f_2> 50 Hz$ $f_1,f_2< 50Hz$ and $f_2> f_1$ $f_1>50 Hz$ and $f_2< 50 Hz$

GATE Electrical 2015 Set 2 | Question: 22
The figure shows the per-phase equivalent circuit of a two-pole three-phase induction motor operating at $50$ Hz. The “air-gap” voltage, $V_{g}$ across the magnetizing inductance, is $210$ V rms, and the slip, $s$, is $0.05$. The torque (in Nm) produced by the motor is _________.
