Abstract

This paper discusses an approach to evaluate the effect of distance on the transient recovery voltage (TRY) waveform resulting from a short-line fault (SLF). Since SLFs can take place at any distance from the breaker terminals, a detailed model of the line in proximity of the circuit breaker is necessary. The main contribution of this paper is to discuss a constant-parameter model that is both effective and simple to use. A second contribution is to describe how to perform SLF simulations to determine the worst case TRY. The described procedure is implemented by means of an example, where the TRY is assessed for a 230 kV breaker.
