Regular insulation testing is one of the most cost-effective methods of identifying aging in any type of electrical equipment. With more than 60 per cent of equipment failures attributed to insulation breakdown, it is a key area to monitor for early identification of potential failures.
Megger has more than 100 years of experience providing high performance insulation testers for electrical equipment diagnostic applications. It offers a huge lineup of insulation testers, including its five-kV insulation tester — the BM5200.
Megger BM5200 is a battery-powered insulation tester with digital and analog arc display, designed for high voltage insulation resistance testing in the maintenance and servicing of cables, rotating plant machinery, transformers, switchgear and industrial applications.
DC insulation tests are performed at 250, 500, 1,000, 2,500 and 5,000 volts. Automatic discharge for capacitive circuits under test is provided and decaying voltage displayed. The guard terminal can be used to minimize the effects of surface leakage and erroneous measurements when carrying out insulation resistance tests.
The company’s lineup also includes the MIT515, the simplest of Megger's new range of small, light five-kV insulation resistance testers for the testing and maintenance of high voltage electrical equipment. Enclosed in a tough case, it is both smaller and lighter than its predecessor.
Now equipped with lithium ion fast rechargeable batteries, the instrument has a large, clear, easy-to-read display, making it suitable for use in both bright and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant. In addition, the elapsed time of the test is displayed constantly, removing the need for a separate timer.
Megger also offers both 10-kv and 30-kV insulation resistance testers. For more information on these and other offerings, contact Megger.
