A megohmmeter is a specialized insulation resistance tester that applies a high dc voltage to a circuit to measure the resistance of its insulation in megohms (mω). The megger test is a method of testing that assesses the insulation resistance, which relays the integrity of electrical insulation between core. A meter megger is an electrical testing instrument used to check insulation condition in equipment such as transformers, motors, cables, switchgear, and generators The megger test is a diagnostic procedure used to measure the insulation resistance of electrical equipment, circuits, and cables
A specialized device called a megger (short for. Insulation resistance testing, often called the megger test, checks how well insulation resists electrical currents This helps prevent failures and extends the life of equipment. For instance if you want to see if a motor is bad, you will “megger test” it, testing each of the three phases of motor to ground and to each other to see if it is shorted to either ground or itself.
