Patent ID: 7844436

Claim:
A method of localizing load coils within a multi-section transmission line between two endpoints, wherein a section of the transmission line is defined as a load coil or a cable section of a specific cable type, the method comprising the steps of: performing a measurement of a Single-Ended Line Testing (SELT) parameter at one of the two endpoints, wherein the measurement provides a measurement of characteristics of the transmission line at a number of frequencies; generating a model of the multi-section transmission line based on a parameter vector θ including parameters describing transmission properties of each section and a length of a plurality of individual cable sections as unknown independent parameters; determining from the model, an approximation of the measured SELT parameter; and determining a length of at least one cable section to thereby localize at least one load coil within the multi-section transmission line by minimizing a criterion function that represents a deviation between the measurement of the SELT parameter and the approximation of the SELT parameter determined from the model.
