Pad mounted transformer
Pad mounted transformer
(OP)
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

That should read if the reading is more that 25 ohms you need another ground rod.
