The tanker needs grounding when refuelling. What's the purpose of this?
The charge accumulated on the tank will be neutralized by the flow of oil.
Only the resulting electrostatic discharge is rapidly connected to the earth's safety, so ground handling is required.
Tanker in the process of refueling, there is a certain mechanical movement, mechanical movement is the risk of static electricity generated, and if there is static electricity, it will lead to spark point.
