The use of fault initiated travelling-wave components in the protection of power lines can provide for faster relay operation. This paper describes the development of several new techniques based on the high frequency travelling-wave information contained in the post-fault voltage and current signals for the protection of teed circuits. The techniques developed have been incorporated in a generalised algorithm for application as a high speed direct-intertrip distance scheme. The underlying principles entailed in the techniques presented in this paper have been outlined on the basis of fault data derived from a single phase line model since this offers maximal simplicity. The authors have chosen to present their findings in two parts; the first paper will be devoted to outlining the underlying principles governing the various techniques and will use data derived from a single-phase model in order to preserve simplicity, whereas a companion paper will describe the extension of the techniques to a three phase system, and will include the performance of the techniques with respect to double circuit lines and teed circuits having a feed-around path.
