Insulation Resistance Tester

The insulation resistance test consists in measuring the insulation resistance of a device under test while phase and neutral are short circuited together.

Insulation resistance tester.

To help eliminate this lack of understanding let s discuss in detail insulation resistance ir testing and the megohmmeter. A perfect solution for insulation testing troubleshooting commissioning and. Whether you work on motors generators cables or switch gear the fluke digital insulation resistance testers provide noise free reliable results. For good insulation the resistance usually reads in the megohm range.

Megger have over 100 years of experience and leadership in providing high performance insulation testers for electrical equipment diagnostic applications. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. 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.

When performing insulation resistance testing you must maintain consistency. Insulation resistance testing should begin at the time of installation and continue throughout the lifetime of the equipment. Insulation resistance testing is used as a quality control measurement. 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. A megohmmeter also called insulation resistance tester teraohmmeter is then used to. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. 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.

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. 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.
