Answer Posted / mohammed amjath
In high voltage we use SF6 or VCB.Because if we go to ACB
the arc quenching will no be proper.Where as if we use vacum
or sulphur hexafloride the arc quenching will be 100percent.

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
kVA rating of ordinary transformer is increased when connected as an auto transformer because A transformation ratio increased B secondary voltage increased C energy is transferred both inductively and conductively D secondary current increased
