Answer Posted / tharanidharan a
In a three pin plug ,the base two pins arranged serially are
PHASE and NEUTRAL. and the top most large sized pin is made
for grounding purpose which is used to protect the device from
shorts(high and low voltages)
example:
when a three point charger is inserted the top larger pin will
touch first than the rest so that the device is prevented by
ground

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?
Draw a circuit diagram in which if button is open we can use socket and bulb as a series test circit and if button is close than simple we can use socket as any load purpose.
