Applying" a voltage, With two conductors that are supposed
to be insulated, the amount of insulation can vary
depending on the thickness of the insulating material, the
amount of moisture, or from being contaminated with an
electrically conductive substance. The insulation could be
thin in one or more spots due to improper manufacture, or
due to overheating, or due to applying excessive mechanical
force, etc. So,
Megging the insulation is intended to
check for any of these imperfections.

When the voltage is applied across two conductors that are
supposed to be insulated, the megohmmeter measures the
current that flows. If the current is lesss than the
specified amount, then the insulation is meeting the
specified minimum. If it fails the test, then there is a
problem such as I mentioned above.

Answer / er.s.ramkumar

Ensure the insulation throughout the cable is good or
not.during the hv test measured leakage current in the
cable is allowable means insulation also good.
