The algorithm applies continuous wavelet Transform (CWT) to locate the dominant charge transient frequency and then fast Fourier transform (FFT) to extract coefficients to be used in the fault location scheme. The fault location scheme managed to identify the correct path of fault location towards the position of the fault using the transient signal recorded from secondary side of the LV substation transformers. The results from intensive simulations and experiments in actual distribution network are also presented in this paper. The final results show that the fault location scheme is able to locate and identify the correct fault location successfully. 2014-03-09T04:50:35Z 2014-03-09T04:50:35Z 2013-10 Article International Review of Electrical Engineering, vol. 8(5), 2013, pages 1520-1531 1827-6660 http://www.praiseworthyprize.com/IREE-latest/IREE_vol_8_n_5.html http://dspace.unimap.edu.my:80/dspace/handle/123456789/32440 en Praise Worthy Prize S.r.l.
