Insulation Resistance Tester
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 tester. Insulation resistance testing is used as a quality control measurement. Portable insulation resistance testers and megohmmeters are designed to help prevent hazards such as electric shock and short circuits caused when the insulation in electrical devices parts and equipment used in industrial plants buildings and other settings degrades over long periods of use. The fluke 1507 is a versatile compact handheld insulation tester for advanced industrial and electrical insulation testing. The insulation resistance test is the second test required by the electrical safety testing standards.
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. Insulation resistance test. 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.
How to test insulation resistance. How significant is insulation resistance testing. Using insulation testing with an instrument such as the fluke 1555 10 kv insulation tester combined with fluke connect technology such leaks can be detected as insulation resistance slowly tapers over time a sign of normal and expected deterioration. 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.
In other cases tests will detect a more serious issue in the moment when current. The measured resistance has to be higher than the indicated limit from the international standards. With advanced performance the insulation tester line is designed to be safe simple to use and gimmick free. A perfect solution for insulation testing troubleshooting commissioning and preventative maintenance applications.
Its multiple test voltages make it the ideal tool for many troubleshooting commissioning and preventative maintenance applications. 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.
