Hi Everybody,
Could anybody advise me any practical article or source of information available on web which contains some pictures or any one of you drop few words about grounding of a 167 KAV pad mounted distribution transformer. I am not sure how to start. It is an instruction to contractor. I think first he should be advised to measure the resistivity of soil and the resistance should be less than 5 ohm.He should bury 10 ft, 5/8 in copper claded steel rod and then calculate resistance. if it is still less than what to do. Add one more but how far from each other. Please advise.
Thanks
