This Coil is used to avoid the continuous supply of the
breaker coil during faulty condition,once we are giving the
closing pulse during uncleared faults condition the breaker
will close one time only. After we are giving many more
closing pulse to the breaker,cannot perform that closing
operation with the help of anti pumping coil.

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?

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
