Cable Insulation Tester

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 relatively same environmental parameters each and every time.

Cable insulation tester.

Cable faults cost money and create disruption so there is an enormous demand for cable test techniques to ensure cables and joints are in good condition and to allow cable faults to be located rapidly. An insulation resistance tester is a test instrument that measures current that leaks through the insulation into ground. 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. With advanced performance the insulation tester line is designed to be safe simple to use and gimmick free.

Whether you work on motors generators cables or switch gear the fluke digital insulation resistance testers provide noise free reliable results. The megger insulation tester is essentially a high range resistance meter. The insulation condition from values that are only relative. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms.

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