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.

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
