Abstract:The requirements for process earthing of different scientific devices in project examples are analyzed according to relevant provisions of current standards & specifications on all types of earth resistance. The practical calculation methods of earth resistance are described. Different earth‑electrode network schemes are developed according to the different needs of scientific devices. The resistance‑reducing methods for earth‑electrode network are compared. The measures for improving earth‑electrode network durability are analyzed.
Key words:earth‑electrode network;scientific device;earth resistance;common earthing;resistance reducing agent;deep well earthing method;soil replacement method;multipoint earthing
