What is the National Standard on an isolated ground point for instrumentation.
Using a earth soil resistivity meter? I know that 25 ohm is standard facility, and 10 ohm is lightning. I have heard that 5 ohm or better is required for the isolated instrumentation gorunding. Is there a written document out there that verifiys this?
