Hi,
I have a question regarding fall of potential ground testing. I'm familiar with the common methods, including the slope method. However, my question relates to test electrode measurement when the surrounding terrain is not flat. Example, I have a substation grounding system at the bottom of some very steep sloped land embankments on a number of sides, around 50 foot high. In this case, initial connections are made to the grounding system at the bottom of the embankment, with the remote current probe and intermediate potential probe on the land at the top of the embankment. I appreciate the measurements are normally just a linear distance. However, how should the distance from the grounding system to the remote current and potential probe be measured in my case? Is this simply measured as a straight line (from a plan view of the site), or should I be measuring up the 'hypotenuse' of the embankment?
If possible, please quote any sources of information in your response.
Thanks in advance.
