TRUJILLO-GUAJARDO, L.A.  e  CONDE-ENRIQUEZ, A.. Educational Software Tool for Protection System Engineers: Distance Relay. Ing. invest. y tecnol. [online]. 2012, vol.13, n.2, pp.215-225. ISSN 2594-0732.

In this article, a graphical software tool is presented; this tool is based on the education of protection system engineers. The theoretical fundaments used for the design of operation characteristics of distance relays and their algorithms are presented. The software allows the evaluation and analysis of real time events or simulated ones of every stage of design of the distance relay. Some example cases are presented to illustrate the activities that could be done with the graphical software tool developed.
