  • High resistance measurement using Megger | Instrumentation

    May 04, 2018 · Megger is used to measure very high resistances, such as those found in cable insulation, between motor windings, in transformer windings. The Megger is essentially a portable ohmmeter with a built-in high voltage source. Meggers may read resistances of several hundred or even thousands of megaohms. They have the advantage, as compared to an ordinary ohmmeter, of applying a high voltage to the circuit under test, and this voltage causes a current if any electrical leakage exists.
