Application of the catenary method and FBG sensors to monitoring ice thickness of power transmission lines

ByL.-M. Li, Z.-M. Liu, Z.-G. Zhang & C.-L. Liu

At present, in the field of engineering, FBG is mainly used in monitoring points of high precision, a high speed real-time monitoring performance, suitable for engineering of the key parts of monitoring and at a moderate cost. A FBG sensor with OPGW or OPPC can constitute a communication network, provide a material basis [4] for real-time remote strain and temperature information monitoring and form an effective real-time remote monitoring system [5]. We propose a model of monitoring the power transmission line’s icing thickness by using the temperature and strain of the line, and then give some experimental results.
