Answer Posted / deepikawalde

A very significant maintenance procedure for checking out the working condition of an electrical system is called IR test or Insulation resistance. It can be said that ht system or equipment is fine when insulation resistance is high.
Megger is an insulation resistance measurement tools for finding the equipment’s insulation resistance. Let us see how is the IR calculated? for more : http://crbtech.in/Electrical-Training/index.php/2017/07/31/define-insulation-resistance-and-its-calculation/
Define Insulation resistance
There is an application of direct current (DC) and not alternating current (AC) and this is the first thing while doing the Insulation resistance test.
