Procedure to Evaluate the Impact in Distribution Single Phase Transformers, Due to Massive Insertion of New Nonlinear Load, Which Changes Daily Demand Graphs

Abstract

Power Electronic development determines 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. Present work introduces a procedure to evaluate maximum permissible load in single phase distribution transformers with massive introduction of a new type of nonlinear load which changes daily demand graphs.
