Importance of ohmmeter
WitrynaThe megohmmeter (or megger) is an instrument for measuring very high resistances, such as the insulation resistance of electrical cables. A high voltage source is required to pass a measurable current through such resistances. Thus, the megger is essentially an ohmmeter with a sensitive deflection instrument and a high voltage source.
