Abstract

The paper presents an original global finite element model developed to understand and quantify the complex phenomena of energetic transfers and overpressures taking place within a transformer vessel during and after a short-circuit. The proposed model is built in order to be used as a CAD tool for power transformers design and protection against explosion and oil fire
