Megger High Voltage Insulation Tester

The case is incredibly rugged and easy to carry being made of tough polypropylene and achieving an ingress protection rating of ip54.

Megger high voltage insulation tester.

The control unit and the high voltage unit. 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. It is both smaller and lighter than its predecessor making it even easier to carry and store. 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.

The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. Megohmmeters also known as insulation testers or megger testers measure resistance to determine current leakage and identify faulty insulation. 1000 v to 5000 v is used for testing for high voltage electrical systems. The hv tester 25 kv is a high voltage generator with a variable negative dc output voltage of 0 25 kv.

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 megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. This division enables the operator to use the test set on site without transport aids. 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.

The ac voltage test set t 22 1 is a portable test set consisting of two separate units. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. Working principle of megger voltage for testing produced by hand operated megger by rotation of crank in case of hand operated type a battery is used for electronic tester. 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.

500 volt dc is sufficient for performing test on equipment range up to 440 volts. 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 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. 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.
