The supply to the megger is given by _____

Right Answer is:

DC generator


DC supply is provided across the terminals of Megger. A megger is a portable instrument, and hence the dc Supply is made available from a small dc generator that forms a part of the instrument.

DC voltage is generated by rotating the generator by hand with the help of a handle provided for the purpose. R is the resistance of the insulation which is to be measured. The hand-driven dc generator provides a constant dc voltage. When dc supply is available, current flows through the pressure coil.
