The Client wants a grounding study in order to "help determine the required number and type of ground rods required to meet the desired resistance level of 5 ohms, plant wide"....Is this a legitimate, realistic request for a system (refinery) governed by NEC?
For Utility High-Voltage Substations, step-touch is more critical (IEEE-80) but with refineries and chem plants we usually simply drove more rods when needed.
Thanks in advance.
