Insulation Resistance Cable Megger Test Report Format

Maintenance insulation resistance testing can be performed on a regular basis and the collected data used to indicate if the conductor insulation is deteriorating over time. Each core to ground continuity point to wire check with low voltage tester check correct installation of cable glands. Screens shall be checked as common conductors.

Start a free trial now to save yourself time and money. Comparing this result with the correct row of table 2 shows that our cable passes the insulation resistance test. If the insulation resistance falls below an accepted user dictated value or falling rapidly over time then cable. Whether the dielectric is good or bad.

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. This type of test is a form of preventative maintenance. Insulation resistance test mohms polarity. Continuity insulation signed notes.

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. The most secure digital platform to get legally binding electronically signed documents in just a few seconds. Because electrical insulation will exhibit dynamic behavior during the course of your test. When performing insulation resistance testing you must maintain consistency.

If the cable does not pass if a cable does not pass the test the cable still may be good but additional cable evaluation should be per formed. The first thing to check is the cable testing environment and cable preparation. During testing all cables and wiring must be completely disconnected from any equipment. After 1 min you should read and record the resistance value.

R1 r2 line earth line neutral. Continuity test report insulation resistance test form ir test sheet test sheets. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. Properly interpreting megohmmeter readings of an insulation resistance test can help you identify faulty or damaged insulation that can lead to these problems.

The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. Routine megger tests of aged electrical cable is a prudent way to ensure your circuits are safe from arc faults that can cause circuits to be blown and safe from fire or electrical shock. If insulation resistance of the cable is found between 1000 and 100 kω km at buried temperature the subject cable should be replaced urgently within a year. For good insulation the resistance usually reads in the megohm range.
