Megger was the combination of Ohm meter+Generator.This
instrument used for measure the high value resistance (IR
value).

Answer / khalidshaikh

1.MEGGER WORKS ON THE PRINCIPLE OF OHM;S LAW.
2.FIRST OF ALL IT GENERATES HIGH VOLTAGE THROUGH ITS
GENERATOR OR DC/AC CONVERTOR AND VOLTAGE MULTIPLIER.
3. MORE THE VOLTAGE GENRATED BY GENERATOR MORE ACCURATE THE
RESULTS.
4.IT CALCULATE THE INSULATION RESISTANCE OF THE CIRCUIT
UNDER TEST BY SUPPLYING HIGH VOLTAGE ON THE ENDS.
5. WHEN THE CIRCUIT HAS HIGH INTERNAL RESISTANCE MORE
VOLTAGE DROP AND LESS CURRENT FLOWS AND VICE VERSA.
IT SUPPLIES THE VOLTAGE AT THE RATINGS OF 1 KV, 2 KV, 5 KV
10 KV , 20 KV AND SO ON.
MORE THE VOLTAGE RATING MEGGER WILL BE ABLE TO MEASURE
MILLIONS OF MEGA OHMS AND UP TO INFINITY LEVEL.

what will be the effect of leading power factor on turbogenerator (and system) that is running parallel with other TG.

When testing an earthing connection, we use a 60 or 100 candle bulb with a phase connected direct from supply and the other wire to the new earthing provided.If the bulb glows then the earth is ok.Else earth connection is not Ok. So, why dont we can use all the home appliances taking a single wire from the phase and the return connection to Earth instead of return connection to neutral?
