Answer Posted / manish gupta
there is much difference in single phase induction motor and three phase induction motor. First,single phase induction motor is not self starting it requires some capacitor to create voltage difference to start.While three phase induction motor is self starting it do not require capacitor to start.
second single phase induction motor is used for small load eg. fan etc. while three phase induction motor for large load eg. lift,elevator etc.
third single phase induction motor uses less power while 3-phase induction motor uses much power.1-phase are smaller in size while 3-phase induction motor are bigger in size

For a 6.6kV Motor it is recommended to do megger test with 500 V d.c and not more than 5kV d.c but the Hi voltage withstand test should be performed by 12kV AC. Why the dc voltage test should be limited but AC voltage withstand test could be with such a high voltage?
