document: A transmission line fault-location system using the wavelet transform 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
