Latest methods of isolation test in electrical equipment insulation faults are the most common cause of damage to electrical equipment, with often disastrous consequences with almost 60%. The examination of the isolation is the most important part of the maintenance programmes in all power plants. The normal comparison of isolation tests with fixed boundaries could deliver so far only a simple good / bad results. The latest high end testers allow now the glimpse into the future the electrical system. Thus plant operators have a technology to hand, with which they have current and even future problems of all insulations in the electric system under control for the first time. “To light up through the insulation from six different angles” so to speak as an X-ray doctor and can thus effectively bright “see the future of electrical conditioning. Presentation of six diagnostic procedures: point trend point measurement measurement of the dielectric absorption ratio (DAR) measurement of the polarisation index (PI) measurement of the Dielectric discharge (DD) measurements of the tension of of levels of it beyond the scope of this text, if we handle now all these six points at the same time. Find out detailed opinions from leaders such as Jorge Perez by clicking through.
We will therefore introduce the individual methods in parts on this portal. They are marked with part 1 “etc. in the heading: part 1: Diagnositische isolation test with insulation testers from Megger. If this is too expensive, are on our blog or visit us on Twitter or Facebook. Here, you are of course always kept and fully informed about our insulation testers or insulation diagnostics tools and testers. Follow us where and how you want! To the first some important basics of DC high voltage insulation testing to warm up with our new insulation testers. Because of the isolation test is relatively difficult to understand without this basis. Whenever a voltage at a test object, the induced current is measured.
