Megger is an instrument used to
measure
A very low resistance
Insulation resistance
Q of coil
Inductance of coil
Insulation resistance
Megger
is a device which is used to measure high insulation resistances.
Hence, the correct option is (B).
&Key Points:-
●It works on the principle of electromagnetic induction. The operation of a megger is based on moving coil meter
●Earth pit resistance is measured with an earth tester, also called as earth megger which can test the resistance across a range of currents and distances.
●Insulation megger is used to measure the insulation resistance of the cables.
