Equivalent Circuits for a Short Circuited Transmission Line and Their Use in Circuit Breaker Testing

This paper covers the development of LC equivalent circuits for the simulation of a lossless short circuited transmission line. A total of eight different equivalent circuits are obtained through the application of circuit theory and residue calculus. Each of the circuits has its advantages and disadvantages depending upon the desired application. In this paper, the equivalent circuits are rated by their ability to simulate a short circuited transmission line in the testing of circuit breakers.
