HT DG: HIGH VOLTAGE generators like 440v/11kv output
LT DG: LOW VOLTAGE generator like 440v

Answer / k.prakashchandra

In HT,field is the rotor and in LT, it may be any.

An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull out torque will occur. The rotor resistance per phase is 0.3 ohm and motor stalls at 650 rpm. The rotor reactance at stand still is A 2 ohm B 1.25 ohm C 3.15 ohm D 2.25 ohm
