The blade down conductor of a wind turbine is a critical component for lightning protection. When the down conductor fails, it can impede the discharge of lightning current, potentially leading to severe consequences such as blade deformation, cracking, or even explosion. This paper focuses on the blade down conductor of wind turbines and designs an online monitoring system for down conductor breakage based on single-wire power transmission technology, radio frequency technology, GPS positioning, and 4G communication technology. The system can monitor the status of the blade down conductor in real time, enabling timely shutdown and maintenance by the staff to prevent more severe damage to the wind turbine. Simulation and experimental results demonstrate that the single-wire power transfer system can achieve signal transmission over 55 m, the radio frequency transmission system can achieve signal return over 100 m, and the communication system can upload detection results in real time. The system can efficiently, stably, and accurately detect down conductor breakage faults.
