Insulation Resistance Tester

Insulation resistance testing is used as a quality control measurement.

Insulation resistance tester.

The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. Whether you work on motors generators cables or switch gear the fluke digital insulation resistance testers provide noise free reliable results. A perfect solution for insulation testing troubleshooting commissioning and. The insulation resistance test consists in measuring the insulation resistance of a device under test while phase and neutral are short circuited together.

With advanced performance the insulation tester line is designed to be safe simple to use and gimmick free. The measured resistance has to be higher than the indicated limit from the international standards. Identifying and correcting problems before they result in a failure occurs through regularly scheduled preventative maintenance. Megger have over 100 years of experience and leadership in providing high performance insulation testers for electrical equipment diagnostic applications.

Whether the dielectric is good or bad to evaluate a number of test results on the same piece of equipment you have to conduct the test the same way and under the. 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. To help eliminate this lack of understanding let s discuss in detail insulation resistance ir testing and the megohmmeter.

We perform extensive insulation resistance testing on 100 of all electrical wired products. The insulation resistance test is the second test required by the electrical safety testing standards. Developed early in the 20th century the insulation resistance ir test is the oldest and most widely used test for assessing the quality of insulation. Because electrical insulation will exhibit dynamic behavior during the course of your test.
