Electrical Insulation Tester Megger

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.

Electrical insulation tester megger. For good insulation the resistance usually reads in the megohm range. Megger testing is harmless to the equipment since a dc voltage is applied to the device. They both test for the insulation properties of electrical wiring motor windings and high power antennae mounts. 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.

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. Temperature humidity moisture and dust particles. 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.

Applications for these instruments include insulation testing continuity testing earth testing loop testing rcd testing pat testing and more. However meggers use a much higher voltage to identify resistances. 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.

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. A megger is basically an ohm meter on steroids. 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. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. 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.
