A monitoring system was built for the landslide of the transmission tower in Maoxian, Sichuan Province, China. Two kinds of optical fiber sensors were used to measure surface displacements and deep displacements. Precipitation was measured by the automatic rain gauge. All these measured data were transferred back to control center by GPRS. There is a good positive correlation between the surface displacement...
Online monitoring of power devices' state is a very important part of the Smart Grid (SM) building plan. Icing on the overhead transmission lines cause great accidents and vast economic loss. In China, icing monitoring technology and relative research is a hot point. The current operating icing monitoring systems based on electrical measurement do not work efficiently because it cannot solve the problem...
Icing on overhead power transmission line is a serious problem that affects the secure operation of power system. This paper firstly analyses transmission line icing damage and the advantage & disadvantage of various current online monitoring techniques. Then, the implementation scheme of a novel method, which based on the sensor network of fiber optic sensor, is introduced. Through measuring...
