Abstract： Ultra–high frequency （UHF） sensor technology is widely applied in this field due to its strong anti–interference capability and high sensitivity. This study aims to optimize the performance of UHF sensors in online monitoring of partial discharge in cables， focusing on improving sensor selection and installation layout to adapt to cable structural characteristics. It also involves developing targeted anti–noise interference and signal identification techniques for the monitoring system， as well as innovating data processing algorithms to enhance feature extraction efficiency and localization accuracy. The results demonstrate that the proposed optimization scheme significantly improves the overall performance of the UHF monitoring system， providing effective technical support for enhancing the reliability of high–voltage cable condition assessment and the safety and maintenance level of smart grids.

Keywords： ultra-high frequency sensor; cable partial discharge; online monitoring system; monitoring optimization; anti-interference technology
