How can we convert the motor to generator and also generator to motor

Answer / shahbaz shaikh
in general motors are the machine which convert electrical energy to mechanical energy so if we want to convert motor to generator then we have to couple the motor shaft with some external turbine or d.c motor or pony motor so bye providing the high speed more then its synchronous speed we can make the motor as generator which have negative slip.

Answer / elvis luis
motors are machines which converts electrical energy to mechanical energy i.e it consumes electrical energy(supply source) and output is mechanical (torque) taken from the shaft output. motor,in case of induction motors, has a speed less than the synchronous speed and a positive slip. for a motor to run as a generator an external prime mover is used so that the motor is forcefully run above its synchronous speed. this allows the motor to run as a generator, in this case the motor now instead of consuming energy from the source starts feeding the source. a motor now acting as a generator has a negative slip.

what is magnetizing current test in power transformer
When calculating the speed of a rotor required for a particular frequency of synchronous generator we use the equation 60f/p Is this p is the number of pole pairs of rotor & do we consider the number of pole pairs in the stator is 1?

Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer?

Any one can explain if there is any harm from humming noise heard from air circuit breaker : we have 415 switch board having two incomers from transformers 3.3KV/415V , when bus coupler closed, and open one ACB incomer to work in one of the transformers, the current started hunting around 50 Amps, and heard humming noise from the air circuit breaker, although the load current was only 1200 amps while the ACB capacity is 2500 Amps, and the transformer 1600 KVA. The same didn't happen when taken the other transformer offline. Why this humming noise and current fluctuation? is there any implication or danger, bearing in mind that we just returned everything back to normal and stopped the maintenance of the transformer. Shall we go ahead and ignore this noise?
