The three-core power cable shares one single shielding with three phase cores. Since it requires a lower voltage insulation and is generally less expensive, the three-core power cable has been widely used in the electrical energy transmission project below 35kV. A known problem for sensing the current of a three-core power cable is that in steady state the total current of three phases is zero, and...
In this paper, an integrated fault diagnosis method is proposed to deal with fault location and propagation path identification. A causality graph is first constructed for the system according to the a priori knowledge. Afterward, a correlation index (CI) based on the partial correlation coefficient is proposed to analyze the correlation of variables in causality graph quantitatively. To achieve accurate...
Multiple InSAR techniques are increasingly being developed for earth observation. However, among them, persistent scatterers-based InSAR (PSI) techniques fail to obtain enough measurement points (MPs) in rural mountainous area due to the lack of persistent scatterers (PSs), such as ma-made structures, rocks, and outcrops, etc. In this paper, Distributed Scatterers-based InSAR (DS-InSAR) algorithm,...
This paper uses CT to gain the energy directly from the high-voltage power line, which is to address the problem of power supply for monitoring system of dynamic increasing capacity in high voltage side of transmission line. The draw-out power coil can induce voltage from the transmission line whose current ranges from 50 to 1000A. Then after rectifying, filtering, voltage reduction and voltage stabilization,...
It had been U.S. Environmental Protection Agency(EPA) suggested the 16 polycyclic aromatic hydrocarbons(PAHs) must take priority of control due to potential harm to people's health. The extensive amount of data show the part of PAHs source from the utilization of the coal. During the coal conversion process, PAHs released may be divided into two categories according to their formation pathways. One...
