ABSTRACT:
A method and localization unit for localizing load coils within a transmission line. The load coil localization is achieved using a measurement of a Single-Ended Line Testing (SELT) parameter for the transmission line and an approximation of the SELT parameter obtained from a model of the transmission line. The model is based on a parameter vector θ including parameters describing the transmission properties of each load coil and cable section and the length of a plurality of individual cable sections as unknown independent parameters. The location of at least one load coil is determined by substantially minimizing a criterion function that represents a deviation between the measurement of the SELT parameter and the approximation of the SELT parameter obtained from the model. The load coil localization method and unit can be used for both symmetric and asymmetric transmission lines.
