Energy supply is a significant resource for economic andsocial development. Statistics show that the lightningphenomenon is one of the most important causes of powersystems outage. On this context, the development of novelmethodologies for the analysis and study of distributionfeeder performance against direct and induced lightning hascontinually been imperative and wanted for researchers,utilities and society.With this purpose, traditional methodologies are usuallycarried out by manual processing. This paper introducesPrincipal Component Analysis (PCA) to extract patterns ofdifferent parameters useful to analyze the distribution feederperformance. Results show that PCA can easily extractpatterns, which can be employed to develop different studieslike sensitivity studies of flashover, back flashoveroccurrence, lightning stroke location.
