Electrical Insulation Tester Megger

A megger is basically an ohm meter on steroids.

Electrical insulation tester megger.

Megger testing is harmless to the equipment since a dc voltage is applied to the device. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. For good insulation the resistance usually reads in the megohm range. Insulation resistance quality of an electrical system degrades with time environment condition i e.

Megger makes electrical test equipment to help you install improve efficiency and extend the life of assets and cable networks at high medium and low voltage. This meter is of special construction with both current and voltage coils enabling true ohms to be read directly independent of the actual voltage applied. 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. Applications for these instruments include insulation testing continuity testing earth testing loop testing rcd testing pat testing and more.

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. Megger offers a wide range of tough high quality hand held instruments which are used to test electrical wiring and other components in domestic commercial and industial facilities and other general business operations. Overview of megger test. Temperature humidity moisture and dust particles.

A colourful history there s more to megger than you know understanding every aspect of the electricity network from generation and transmission to distribution and consumption is what it takes to be the world leader in cable test diagnostic and fault location solutions. They both test for the insulation properties of electrical wiring motor windings and high power antennae mounts. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. The insulation resistance test a k a the megger test is as relevant as ever and in many applications is preferred to other insulation test methods.

The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. Today megger offers the finest line of 5 kv 10 kv and 15 kv dc insulation resistance testers available anywhere. 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. For good insulation the resistance usually reads in the megohm range.
