I think Mr.Kishore kumar said answer is correct.i.e. R=Pl/a
area of the conductor increases resistance
value dicreases .so high leakage current flows it thats why
the area of the earthing pin is big compare yhe phase and
neutral pins.

Hi My dear all Friends, There is a question regarding HVAC Engineering and widely used in Power Projects. Question- What is the diffrence Between REF, SEF and Differential Protection....???? Where REF - Restricted Earth Fault SEF - Senstive Earth Fault.
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.
