High Voltage Insulation Tester

Power frequency high voltage insulation tester dry type dc ac test transformer.

High voltage insulation tester.

100 kva ac high voltage insulation tester for power testing transformer. 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. Industrial computer insulation test equipment for voltage withstand test. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator.

High voltage insulation testers kew 3127 insulation resistance up to 10tω short circuit current up to 5ma wide test voltage from 250v to 5000v diagnostic insulation tests. China high voltage tester catalog of vlf hipot tester 30kv 50kv 80kv high voltage very low frequency hipot tester oil type high voltage insulation tester ac dc hipot tester provided by china manufacturer chongqing gold mechanical electrical equipment co ltd page1. The ir3455 is a 5 range 250v to 5000v digital insulation resistance tester offering up to 10tω of insulated resistance testing. Portable high voltage switch testing equipment for loop contact resistance.

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. Megohmmeters also known as insulation testers or megger testers measure resistance to determine current leakage and identify faulty insulation. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. High performance features include bargraph built in memory leak current and voltage testing and dar and pi calculation capabilities to help shorten work time associated with field insulation testing.

For good insulation the resistance usually reads in the megohm range. Wide test voltage from 250v to 5000v diagnosis function of pi and dar newly designed alligator clip it comes with a tough hard case filter function reduces noise interference for obtaining stable measurement. Comes with test leads eight c batteries 120v ac adaptor heavy duty carrying case and user manual. Hioki s electrical safety testers withstand voltage testers insulation resistance testers protective continuity testers and leakage current testers comply with iec 61010 1 jis c 1010 1 and other applicable standards laws and regulations.
