Insulation Resistance Tester

Because electrical insulation will exhibit dynamic behavior during the course of your test.

Insulation resistance tester.

For good insulation the resistance usually reads in the megohm range. Whether you work on motors generators cables or switch gear the fluke digital insulation resistance testers provide noise free reliable results.

We perform extensive insulation resistance testing on 100 of all electrical wired products. Megger have over 100 years of experience and leadership in providing high performance insulation testers for electrical equipment diagnostic applications. A perfect solution for insulation testing troubleshooting commissioning and. 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.

Insulation resistance testing is used as a quality control measurement. To help eliminate this lack of understanding let s discuss in detail insulation resistance ir testing and the megohmmeter. The measured resistance has to be higher than the indicated limit from the international standards. The insulation resistance test consists in measuring the insulation resistance of a device under test while phase and neutral are short circuited together.

The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. Insulation resistance meters that can generate two or more rated measurement voltages since different insulation testers provide different combinations of rated measurement voltages it is necessary to choose an instrument that provides the combination of values that is best suited to the application at hand. A megohmmeter also called insulation resistance tester teraohmmeter is then used to. 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.

With advanced performance the insulation tester line is designed to be safe simple to use and gimmick free. Identifying and correcting problems before they result in a failure occurs through regularly scheduled preventative maintenance.
