8 10103what is the difference in using the 125% and the 250% factor of safety in calculating circuit breakers capacity for motors,which is more reliable to use the 125% or 250%??
1 4483sir , what happen if we decrease ( approx 3 inch ) the lenth of shaft in 110KW Induction , three phase motor. actually a 110KW motor is couppled with star couplling to 120TR compressor. When we doing maintenance in compressor it is required to skid the motor backword and resulting dis- alightnment . so we want to change the tyre coupling in place of existing coupling. so it is required to cut off the rotor aprox 3 inch form driving side.
2 4222The following equipment are installed ia a plant 1. 110KW Induction motor 4 Nos 2. 30 HP motor 3 Nos 3 15 HP Motor 3 Nos 4 7.5 HP motor 4 Nos what is total load of plant if one of each is stand by.
