| Abstract: | In order to solve the problem of health monitoring of high - voltage transmission tower,a PVDE piezoelectric sensor is designed. The sensor can detect the natural frequency of high - voltage transmission tower. By comparing the measured natural frequency with the natural frequency in health, the high - voltage transmission tower damaged or not can be distinguished. Test results show that the PVDF piezoelectric sensor works well,so it can be used for the actual information collection. |
