  Re: What is the min and max ohmic value for earthing?
Answer
# 2		 it's depend on system
Basicaly for LV system it should be less than 1 ohm and
for MV system it should be in rage of 1 to 5 omh
ideal is 0 resistance but practically it is not possible 
Is This Answer Correct ?    32 Yes 0 No

  Re: What is the min and max ohmic value for earthing?
Answer
# 4		 It is depending on usage
LV- for copmutor/ electronic device --- 0- 1 ohm
for UPS --- 0- 1 ohm
HV - for substaion/ power generating system- 0- 5 ohm

but 0 is not possible.

  Re: What is the min and max ohmic value for earthing?
Answer
# 7		 For derty Earth: the min is zero as ideal case and the
maximum shoildn't more that 1.5 ohm.

For Clean earth the min as before and the maximum is 1 ohm.

  Re: What is the min and max ohmic value for earthing?
Answer
# 8		 minimum ohmic value will be even lees than 1 ohm which must
be calibrited during earthing.maximum value will be up to
10 ohms for example lightining protection system earthing 
Is This Answer Correct ?    1 Yes 3 No
