The Application of the Optic Sensor in the Monitoring on the Transmission Lines

Abstract:

Three technologies of insulator online monitoring based on optic fiber sensors is described in proposed paper, including optic fiber sensor salt density technology, optical fiber composite insulator monitoring technology and optical sensor insulator surface electric field detection technology. According to measuring insulator surface ESDD, the internal stress and the temperature distribution of the composite insulators and insulator surface electric field values. these technology can monitor the operation performance of insulator. These techniques that improve the existing insulators monitoring methods has a strong innovative and practical application prospects.
