Electrical megger test.

Megger makes electrical test equipment to help you install improve efficiency and extend the life of electrical assets and cable networks at high medium and low voltage. The generator can be hand cranked or line operated to develop a high dc voltage which causes a small current through and over surfaces of the insulation being tested fig. It should always be kept in mind that technically this test should always be addresses or called insulation test. The megger test is a method of testing making use of an insulation tester resistance meter that will help to verify the condition of electrical insulation.

To electrical insulation testing. 6 a stitch in time the generator can be hand cranked or line operated to develop a high dc voltage which causes a small current through and over surfaces of the. Megger is a brand name and not a test description although mostly the equipment being used for this test is branded megger.

A megger is an ohmmeter that measures resistance in the megohm scale. The megger test is a method of testing making use of an insulation insulation tester resistance meter that will help to verify the condition of electrical insulation. Megger tests are performed using a meg ohmmeter. To test a cable with a megger you connect one probe to the outside of the cable and with the power turned off you touch the probe to the conducting wire at the point of connection.
