Buchholz relay is installed in inclined position because of its function as it is used for internal fault protection inside the transformer as in case of over heating and loading of transformer oil temperature also increases hence oil expands inside the body of transformer so that excessive oil expands during heating or time of fault enters in buchholz relays body and after a particular level relays coil get trips and gives an alarm to the operator regarding the fault.

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 slip when motor stalls is A 1 B 0 C 13.33% D 10.33%
