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.
Digital insulation resistance tester megger.
Megger bm5200 is a battery powered insulation tester with digital and analogue arc display designed for high voltage insulation resistance testing in the maintenance and servicing of cables rotating plant machinery transformers switchgear and industrial applications.
With just a little research on electrical talk websites i determined that a rule of thumb is 1 megaohm per 1 000 volts plus 1 megaohm for safety margin.
I had basic knowledge of using a megger but no idea what the cutoff was for acceptable insulation resistance values.
It is both smaller and lighter than its predecessor making it even easier to carry and store.
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.

Offering cat iv the mit515 is the simplest of megger s new range of small light 5 kv insulation resistance testers for the testing and maintenance of high voltage electrical equipment.
Fluke s digital insulation resistance testers provide reliable results whether you work on motors generators cables or switchgear.
The megger company registered the name megger in may 1903 and today offers a wide variety of ir testers.
