Meggar is a brand name.

Answer / ramkumar

The resistance of high voltage insulators is normally in the order of Terra Ohms and cannot be measured by Megger or any other such instrument. What these instruments measure is only the surface resistance but what defines an insulator is its bulk or volume resistance. The ideal way is to put a guard electrode and ground the surface leakages and then measure the resistance using appropriate measuring set up.

Answer / pramila raj

The two instruments you will use most often to check continuity, or to measure the resistance of a circuit or circuit component, are the OHMMETER and the MEGGER (MEGOHMMETER).
