Structural Health Monitoring (SHM) is a novel and continuously developing branch of science and technology that draws attention of scientists all over the world. It creates opportunities to detect, localize and identify structural damage of various types such as: line breakage, permissible sag, bolt loosening, fatigue cracking or insulator contamination. On the other hand the methods used to estimate the remaining operational time and self-healing are still at the proof-of-concept level. All these issues should be addressed by the Smart Grid Technology and also are pointed out by the Electric Power Research Institute [1]. The authors of this paper carried out a wide literature review related to structural health monitoring of overhead power transmission lines and their supporting structures. Based on this devices existing in the field are also presented and discussed. Last, but not least, authors’ concept of an electric power line monitoring system based on fibre sensors is introduced. The authors suggest the application of distributed sensing networks with Fibre Bragg Grating (FBG) sensors or Brillouin sensors to measure strains induced by icing, temperature or current loads. Based on the data collected various useful safety factors can be calculated, i.e. the icing level or remaining current load related with the permissible safety distance between power lines.
