AbstractIn this thesis a new analytical technique for the evaluation of fault initiated transients has been developed. The technique is very general and is applicable to both the transposed and untransposed polyphase multi-conductor lines of any configuration, and, can take into account the frequency dependence of the parameters of the system. On the basis of this technique the following types of faults can be easily studied: (a) shunt faults (b) series faults (c) simultaneous shunt or series faults or their combination at one or multiple locations. The post fault transient behaviour of ehv ac transmission line has been simulated by using digital computer. The faiilt transient response at the relaying points are presented for a number of interesting cases. This information is of particular interest for the design and development of super-speed protective schemes ehv lines. The phenomenona of fault induced overvoltage has also been investigated briefly. The results for fault induced overvoltage show excellent agreement with Kimbark's field test results. Digital simulation of the transient behaviour has been achieved by a very efficient programming technique.
