Abstract

This paper describes a method of distribution transformers loading estimation, using the fuzzy logic technique of representation of loading levels of transformers by linguistic variables and their associated trapezoidal membership functions. The method was developed for some hundreds of distribution transformers of the Israel Electric Corporation (IEC). Based on this method, it is possible to estimate the lateral and segmented medium voltage (MV) feeder loads and losses for reconfiguration purposes
