Insulation Resistance Tester

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

Insulation resistance tester. The insulation resistance test is the second test required by the electrical safety testing standards. Identifying and correcting problems before they result in a failure occurs through regularly scheduled preventative maintenance. 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. 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. A megohmmeter also called insulation resistance tester teraohmmeter is then used to. The insulation resistance test consists in measuring the insulation resistance of a device under test while phase and neutral are short circuited together. Because electrical insulation will exhibit dynamic behavior during the course of your test.

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. A perfect solution for insulation testing troubleshooting commissioning and. 817 377 wire 9473 request a quote. Insulation resistance testing should begin at the time of installation and continue throughout the lifetime of the equipment.

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. Whether you work on motors generators cables or switch gear the fluke digital insulation resistance testers provide noise free reliable results. 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. When performing insulation resistance testing you must maintain consistency.
