Based on the magnetic principle

the virtual hanging criterion of the grounding wire is determined

the anti-virtual grounding wire fixture is developed. The GPS and front-end video are used to monitor the application status of the grounding wire

and the connection removal state monitoring and alarm background of the grounding wire is developed in the paper. The field application shows that the smart grounding wire complete device can realize real-time and on-the-spot intelligent control of the grounding wire on the site

and prevent the occurrence of misoperation accidents such as virtual hanging

mis-installing

detaching

wrongly removing for the grounding wire

which provides a reference for operation dispatcher and overhaul commanders to keep track of the temporary ground connection on the line any time.
