Megger High Voltage Insulation Tester

The hv tester 25 kv is a high voltage generator with a variable negative dc output voltage of 0 25 kv.

Megger high voltage insulation tester.

Now cat iv 600 v this new 10 kv insulation resistance testers from megger are designed specifically to assist you with the testing and maintenance of high voltage electrical equipment. Offering cat iv the mit525 is compact light 5 kv insulation resistance tester for the diagnostic testing and maintenance of high voltage electrical equipment. The condition of the test object with regard to electrical strength and insulation quality can be determined on the basis of the unit s readings for output voltage and current. The case is incredibly rugged and easy to carry being made of tough polypropylene and achieving an ingress protection rating of ip54.

1000 v to 5000 v is used for testing for high voltage electrical systems. 500 volt dc is sufficient for performing test on equipment range up to 440 volts. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. It is both smaller and lighter than its predecessor making it even easier to carry and store.

This division enables the operator to use the test set on site without transport aids. Megohmmeters also known as insulation testers or megger testers measure resistance to determine current leakage and identify faulty insulation. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. For good insulation the resistance usually reads in the megohm range.

The megger tpt320 voltage tester provides electricians and electrical engineers with voltage indication but has additional functions features that makes the instrument a versatile instrument. The test set can be equipped with a rectifier attachment for dc voltage testing up to 80 kv. 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. This meter is of special construction with both current and voltage coils enabling true ohms to be read directly independent of the actual voltage applied.

The tpt320 features both lcd and led displays that provides ac and dc voltage measurement from 12 to 690 volts in addition a continuity function. Fluke s digital insulation resistance testers provide reliable results whether you work on motors generators cables or switchgear. The control unit and the high voltage unit. 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.
