Electrical Insulation Tester Megger

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.

Electrical insulation tester megger.

A megger is basically an ohm meter on steroids. Temperature humidity moisture and dust particles. Insulation resistance quality of an electrical system degrades with time environment condition i e. For good insulation the resistance usually reads in the megohm range.

In particular our line of s1 series insulation testers offers unparalleled capability including battery or line operation best measurement ranges highest noise resistance five automatic tests data storage rs232 or. However meggers use a much higher voltage to identify resistances. 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. 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.

Overview of megger test. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms.

Today megger offers the finest line of 5 kv 10 kv and 15 kv dc insulation resistance testers available anywhere. 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. 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. 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. Applications for these instruments include insulation testing continuity testing earth testing loop testing rcd testing pat testing and more. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. Megger testing is harmless to the equipment since a dc voltage is applied to the device.
