Abstract

This paper presents a fast software to compute the three-dimensional (3D) leakage field in shell type power transformers up to 500 kV. The proposed software, Shell-RNM(3D), is based on the reluctance network method (RNM) and developed in EFACEC Energia. Shell-RNM(3D) is appropriated to assess stray losses, optimization of shunts and screen position, and hot spots localization. Also it enables to analyze and conclude optimal use of screens, changes in geometrical structure made of non linear materials, etc. A highlighted application of Shell-RNM(3D) for evaluating the stray losses on stepped shunts, as well as an advance of the setup for carried out experimental measurements by means of fiber optic are described.
