Answer / prabhakar

By operating the motor over the synchronous speed, the
motor will run as a induction generator

Answer / sidda raghavendra

* For an induction machine:

at the time of starting if we can set the speed of the
machine is just less than its synchronous speed it works as
induction motor as we must give electrical power as input

at the time of starting if we can set the speed of the
machine is just higher than its synchronous speed it works
as induction Genearator as we must give Mechanical
(steam,hydral or diesel and so on) power as input

*For synchonous machine:

Its all depend on only the input of the machine

Answer / balaji

by making slip value negative..

Answer / sujata

motor is a machine which converts electrical energy into
mechanical energy and generator is a machine which converts
mechanical energy into electrial energy.
So this depends on us that how we are using that machine .
if we will provide mechanical energy to its shaft then it
will start generating electrical power and you will call it
generator.
and if you will provide electical supply to it then it will
give mechanical power then you will call it motor

Answer / srinivas

By changing the slip value. The slip value of motor is
greater than 1, then it acts as a generator

Answer / suresh apgenco

on 22.03.2015 at 17:15hrs Y phase 66kV class Power Trf-2 Current transformer has flashed over and oil came out. The failed CT has been replaced on 24.03.2015 at 13:15hrs and the Trf has been charged in presence of RT Hassan after conducting the pre-commissioning tests. On the same day at 17:00hrs the commissioned CT has again flashed over and immediately the Trf  has been isolated from power supply. It is confirmed the secondary is not opened and checked the earth integrity and is found ok. Here what would be the reason for the CT failure?
