However, the electrical equipment of the crane has a large capacity, so it is necessary to carry out protection grounding test to reduce the probability of electric shock during the operation of the crane and ensure the safety of production. Therefore, it is necessary to carry out the inspection and testing of crane protection grounding circuit, crane protection external grounding connection and protective electrical device on the basis of understanding the structure of crane protection grounding system and the importance of crane protection grounding inspection and testing.展开更多
