The speed at which an induction motor will operate depends
on the input power frequency and the number of electrical
magnetic poles in the motor

Answer / samarjit gope

the speed at which field rotates is called synchrtonous
speed

Answer / kapil bahadure

when three phase induction motor connect on suplly then
rotating magnetic field produced by stater widing.the speed
of rotating magnetic field is colled as synchronous speed
of a three phase induction motor.

synchronous speed= 60*2/p
p=no of pole.

Answer / gopalakrishnan

synchronous speed= 120* supply frequency/no of poles

Answer / shinyvikram ganji

THE MAXIMUM SPEED IS CALLED SYNCHRONOUS SPEED

The unit of quantity of electricity is the:(a) volt(b) coulomb(c) ohm(d) joule

there is a power transformer 66/11kV in delta-delta connection has 5 feeder coming out from the secondary side. One of the feeder in it normally loaded (loaded than other feeder)and this feeder usually trips with double OCR causing the bank transformer to trip. Now if the load of this feeder is put on other transformer then that no problems occurs on that transformer or the load. However normally all the test(IR, PI, short ckt, open ckt,grounding test and other ) has been conducted for this but evertything transformer..... I am not geting what is the actual problem...
