Instrument system grounding

Can the working ground and protective ground of the instrumentation system be connected to a single grounding electrode separately, without sharing that same electrode with the electrical grounding network? This post was last edited by cim117 on 2009-2-12 15:01.]

I believe that work grounding should not be connected to the electrical grounding system.

In modern advanced DCS grounding systems in China, both the working ground and the protective ground are ultimately connected to the electrical ground electrode
