Abstract: Power electronic development determines the introduction of nonlinear devices in electric power systems. Introduction of nonlinear devices increase current harmonics in transmission and distribution power systems. Distribution transformers and feeders increase power losses and their nominal parameters are reduced. The present work introduces a procedure to evaluate maximum permissible load in single phase distribution transformers with the introduction of a new type of nonlinear load which changes daily demand graphs.

Keywords: current harmonics; stray losses; statistical inference; daily demand graphs (search for similar items in EconPapers)
