Abstract

This paper briefly introduces the principles of linear 3-pole wiring method to form current circuit through soil to measure grounding resistance; discusses the feasibility of linear 3-pole wiring method to measure the grounding resistance of buildings (structures) in water; adopts comparative method to carry out field measurement on the grounding resistance of representative grounding devices in water and the grounding resistance of grounding devices in the soil adjacent to water; discusses the applicability and validity of linear 3-pole wiring method to measure the grounding resistance of buildings (structure) in water through variance analysis and correlation coefficient analysis methods, and solves the problem about how to measure the grounding resistance of buildings (structures) in water.
