Protective scheme for series-compensated transmission lines

The problem of determining fault position on a series-compensated power line is considered and a novel measuring scheme based on definite integrals of relaying current and voltage is described. Attention is given to the effect of travelling-wave distortion of relaying signals in designing a prototype single-phase relay. Details of the equipment construction are given together with laboratory tests on a lumpedparameter line model and digital-computer simulated tests on a distributed-parameter line model.
