For the LNG tank area under construction, it is necessary to consider whether lightning protection grounding and static electricity grounding can share the same grounding electrode. I would appreciate some expert advice on this matter; which standards should I refer to? Thank you all for your help
It is a ground grid that can be connected together. Refer to GB 50057
I know that gas cabinets use a separate lightning protection system, but I’m not sure about liquefied gas tanks. I think there isn’t much difference between the two; it seems that the lightning protection system cannot be connected directly to the tank body, and some isolation measures are required. I’m not sure if this is correct – please let those with expertise give their opinion.
A combined grounding system can be used, but attention should be paid to the grounding resistance value.
As long as the ground resistance meets the specification requirement of being less than 4 ohms, it can be connected upward
