Research on Cable Surface Condition Sensing Technology Based on High-Precision Array Flexible Sensing Units

This study introduces a novel cable surface condition sensing technology that employs a high-precision array of flexible sensing units to detect minor changes such as deformation, pressure, and damage on the cable surface in real-time. The manufacturing process of the flexible capacitive tactile sensors, including the preparation of PVDF films and the assembly of Ni-PU films, was elaborated. The experimental results demonstrated the sensor's rapid response and high sensitivity, meeting the requirements for cable surface state monitoring. The innovation of this paper lies in its comprehensive and real-time monitoring capability, which is crucial for early warning and health surveillance of cable damage, thereby enhancing the intelligent and detailed management of power systems. The original contribution is the application of flexible sensing arrays for early detection and health monitoring of cable damage, providing significant support for cable maintenance and replacement decisions.
