Insulation Resistance Test Megger

For good insulation the resistance usually reads in the megohm range.

Insulation resistance test megger.

The test measures the insu lation resistance between the phases and or between phase and ground. Megger bm5200 is a battery powered insulation tester with digital and analogue arc display designed for high voltage insulation resistance testing in the maintenance and servicing of cables rotating plant machinery transformers switchgear and industrial applications.

Fluke s digital insulation resistance testers provide reliable results whether you work on motors generators cables or switchgear. 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 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.

Written by steve wetzel mark dulik on april 24 2019 in megger testing. Insulation resistance testing purpose. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. When performing a test using the megger in addition to checking the condition of the insulation and verifying if its dielectric strength is sufficient the test should also determine the ohmic value of the insulation resistance during the current flow.

Insulation resistance testing is a non destructive test procedure. It is commonly used in the industry for acceptance testing prior to energizing the cable and for maintenance testing programs. Insulation resistance testing megger testing. Megohmmeters also known as insulation testers or megger testers measure resistance to determine current leakage and identify faulty insulation.
