New Types of Sensors for Smart Grid

Sensors and sensor networks have an important impact on meeting environmental challenges. In this chapter, the use of fiber optic sensors (FBG: fiber‐optic Bragg grating) for building smart transmission network, and the use of magnetic sensors to build non‐contact measurement of current to realize specific purposes, are presented. The novel applications of advanced magnetic sensors in smart grid include point measurement of transient magnetic field, non‐contact fault location of transmission lines, non‐contact operation state monitoring and electronic current transformers. The icing monitoring and power system surveillance with FBG fiber optic sensor are presented.
