Insulation Resistance Tester

With advanced performance the insulation tester line is designed to be safe simple to use and gimmick free.

Insulation resistance tester.

Since 80 of electrical maintenance and testing. The insulation resistance test consists in measuring the insulation resistance of a device under test while phase and neutral are short circuited together. Since 80 of electrical maintenance and testing involves evaluating insulation integrity the answer is very important electrical insulation starts to age as soon as it s made. In other cases tests will detect a more serious issue in the moment when current.

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. The insulation resistance ir test also commonly known as a megger is a spot insulation test which uses an applied dc voltage typically either 250vdc 500vdc or 1 000vdc for low voltage equipment. Insulation resistance test.

The first dc portable insulation tester was developed in 1889 by our founders sydney evershed and ernest vignoles and by 1903 was being sold as a megger insulation tester. Its multiple test voltages make it the ideal tool for many troubleshooting commissioning and preventative maintenance applications. Hands down without a doubt one of the most universally searched topics on ec m s website from a historical perspective is insulation resistance testing as a result some of our most popular evergreen articles like understanding insulation resistance testing continue to top the charts when it comes to most popular content. And aging deteriorates its performance.

How to test insulation resistance. 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. A perfect solution for insulation testing troubleshooting commissioning and preventative maintenance applications. The insulation resistance test is the second test required by the electrical safety testing standards.

The fluke 1507 is a versatile compact handheld insulation tester for advanced industrial and electrical insulation testing. How significant is insulation resistance testing.
