摘要：In the field of fault location within a power transmission network, there is

provided a method of determining a fault location (20) in a power transmission conduit(10) which comprises the steps of: (a) sampling at an original sampling frequency a signal(i(t), i(t), ic(t)) propagating through the power transmission conduit (10) to establish a firstdata set (i(n)) including a plurality of sampled signal characteristics; (b) interpolating thefirst data set (i(n)) to establish a second data set (i(n)) including an increased number ofsignal characteristics whereby the second data set (i(n)) has an equivalent samplingfrequency higher than the original sampling frequency; (c) identifying a fault wave signal(22) within the second data set (i(n)); and (d)utilising the propagation characteristics of thefault wave signal (22) to determine the origin of the fault wave signal (22) within thepower transmission conduit (10).
