title: A transmission line fault-location system using the wavelet transform
abstract: This paper describes the locating system of line-to-ground faults on a power transmission line by using a wavelet transform. The possibility of the location with the surge generated by a fault has been theoretically proposed. In order to make the method practicable, the authors realize very fast processors. They design the wavelet transform and location chips, and construct a very fast fault location system by processing the measured data in parallel. This system is realized by a computer with three FPGA processor boards on a PCI bus. The processors are controlled by UNIX and the system has a graphical user interface with an X window system
