Cable Insulation Tester

The megger insulation tester is essentially a high range resistance meter.

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. Whether you work on motors generators cables or switch gear the fluke digital insulation resistance testers provide noise free reliable results. 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. Because electrical insulation will exhibit dynamic behavior during the course of your test.

An insulation resistance tester is a test instrument that measures current that leaks through the insulation into ground. For good insulation the resistance usually reads in the megohm range. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. We look for corrosion on the copper cracks in the insulation moisture on the cables and many other indicators of damage to the cables.

A cable insulation resistance test is a test that is performed by applying 500 v or more between the conductor and ground and measuring the resulting leakage current. With advanced performance the insulation tester line is designed to be safe simple to use and gimmick free.
