Mathematical Study on Traveling Waves Phenomena on Three Phase Transmission Lines – Part I: Fault-Launched Waves

A mathematical study on the traveling waves (TWs) propagation phenomena on three-phase power lines under fault conditions is presented in this article. This article is divided into two parts, and this part focuses on the analytical development of expressions that describe fault-launched TWs as functions of line and fault parameters. From the obtained mathematical representation of TWs launched by faults, TW-based applications can be designed in a more reliable way, justifying the relevance of the presented study.
