Historically many field electricians use the somewhat arbitrary standard of 1 megohm per kv. It is commonly used in the industry for acceptance testing prior to energizing the cable and for maintenance testing programs. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. The megger test is a method of testing making use of an insulation tester resistance meter that will help to verify the condition of electrical insulation.

Insulation resistance testing is a non destructive test procedure. Also acceptable values of insulation resistance depend upon the equipment you re testing. Insulation resistance testing purpose. Continuity test report insulation resistance test form ir test sheet test sheets post navigation battery autonomy test report for fire alarm system testing commissioning report smdb.

To test a cable with a megger you connect one probe to the outside of the cable and with the power turned off you touch the probe to the conducting wire at the point of connection. During testing all cables and wiring must be completely disconnected from any equipment. The following is a summary of insulation resistance ir testing commonly referred to as megger testing of low voltage cables rated less than 5 kv recognized by nexans. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms.

It is commonly used in the industry for acceptance testing prior to energizing the cable and for maintenance testing programs. The test measures the insulation resistance between the phases and or between phase and ground. For good insulation the resistance usually reads in the megohm range.
