Abstract
With the rapid development of radio and television industry,the problem of safe operation of radio and television engineering has been widely concerned.The use of grounding technology can effectively protect the radio and television equipment and maintain the normal operation of the system.Based on this,the paper introduces common grounding techniques,including lightning protection grounding,protective grounding and anti-interference grounding.This paper describes the points for attention in the application of grounding technology in the construction of radio and television projects,including maintaining the scientific grounding connection sequence,reasonable layout of grounding current,ensuring the normalization of operation,and ensuring the zero neutral potential of three power sources,so as to give full play to the advantages of grounding technology.
