This letter presents a parameter-free fault location algorithm on a two-terminal double-circuit transposed line with unsynchronized terminals. The presented algorithm is formulated using positive-sequence components of measurands at both terminals. The salient features of the proposed method are that it is non-iterative and does not require pre-fault data. Also, it considers distributed parameter model of a line unlike existing techniques, which adopt lumped model of a line. Simulation results using EMTP-RV platform alongside the results with field data of Power Grid Corporation of India Limited (PGCIL) are presented. The test results established the validity and accuracy of the proposed algorithm.
