Investig. [online]. 2015, vol.35, suppl.1, pp.104-109. ISSN 0120-5609.  https://doi.org/10.15446/ing.investig.v35n1Sup.53457.

This paper presents a proposal for the development of an automatic system correlation between two variables, one represented by the failures on the electrical distribution lines during a storm process and another one represented by atmospheric discharges (lightning) that happen in this process. Initially, in order to define if the failure is caused directly or indirectly by an electrical impact generated by lightning, a space-time correlation is proposed. With the obtained data a decision matrix is proposed, using an entropy method to assign weights to the failures in order to determine its severity and therefore its priority of attention. On the other hand, taking into account that the time window of observation is perhaps the most relevant parameter in the proposed correlation system, this article shows part of a simulation proposed for its calculation as well as the mathematical bases that were used as a support for it.

Palavras-chave : Lightning; correlation; failures in distribution lines; method of entropy; decision making.
