Abstract:The grounding system of medium and short wave radio station room mainly consists of working grounding,technical grounding (high frequency grounding),protection grounding,lightning protection grounding and other systems. For various grounding systems,the grounding resistance and grounding devices are mainly analyzed. Through the analysis of the engineering burying of artificial grounding body,natural grounding body and lightning protection grounding,as well as the different burying methods of various grounding devices,and the different calculation methods of grounding resistance,it helps to design the grounding resistance Engineering of the computer room grounding system,so as to reduce the grounding resistance of the computer room. This paper briefly introduces the detection of the grounding resistance,the connection and layout of the correct use of the grounding resistance tester,and the test method.

Keywords:broadcast machine room;grounding resistance;ground resistance test
