Ice accretion has been a huge threat for the stable operation of transmission line. Icing monitoring devices used presently are active sensors with low working stability. Signals are transmitted in the electrical form, which are easily affected by the electromagnetic interference. In this paper, an online icing monitoring device of transmission line based on fiber bragg grating (FBG) sensor is designed, and is operated as a pilot unit on the 44# tower of 110kV Zhenzou line. Experimental results show that the online icing monitoring device operates stably, and the designed fiber bragg grating sensor has high linearity, good sensitivity and high accuracy.

In order to solve the problem of insufficient energy supply of the on-line monitoring device of the transmission line, a sensor energy acquisition scheme directly installed on the transmission line is proposed. In the current power supply, induction power supply is a kind of energy extraction method with better practical applicability. Since the monitoring devices and electronic equipment on the transmission line are often in a strong magnetic field and high voltage environment, designing a stable and reliable power supply is the guarantee for the stable operation of the monitoring devices and electronic equipment. This paper presents a structure of energy-absorbing iron core with two semi-circular magnetic cores, and studies the magnetic saturation problem in the inductive power supply and the design of the DC output circuit.

Bragg Grating Sensor

Galloping and ice shedding, two of significant dynamic damages to bundle conductors, are both typical three-degree-of-freedom vibrations, while few technique is studied on monitoring the torsion oscillation of the whole bundles and the sub-conductors. For the monitoring of the vertical, horizontal, and especially torsional oscillations, a novel type of spacer damper is developed, which can also detect the torsion motion of each sub-conductor, with consideration of the special configurations of bundle cables and integrated with fiber bragg grating sensors. Then, a distributed FBG network is introduced.
