要約(日本語): This report presents the effect of measuring system on the fault location system, developed by one of the authors, using Wavelet transform implemented by the hardware(FPGA). The measuring system is a condenser type potential divider. This divider includes an inductor which usually has nonlinearity. Considering the nonliarity, we analyse the input surge voltage to the divider which is described by Laguerre function of the time and also the output voltage from it. Both input and output waves are transformed by Wavelet transform. The difference between the zero-crossing points of input and output waves can be seen very small. As a coclusion, we can say that the output wave is possible to use for the input of the fault locating system by means of Wavelet transform.
