Modeling continuous windings under transients with TLM and ATP

Abstract

This work presents the performance of the well-known program ATP-Alternative Transient Program applied to the simulation of continuous windings of transformer under the incidence of a voltage surge. The motivation for this analysis lies in the fact that once ATP is widely applied for circuit simulation in several conditions, it is expected that it can also be applicable to this problem that is of significant importance for transformer designer. If so, thanks to wide ATP availability designers will have available an easy and user friendly tool for helping in their designs. Basis of analysis is in new experimental data obtained by the authors as well as some other data presented in previously published paper, in which experimental data have also validated applicability of the TLM- Transmission Line Modeling Method for the same problem, known as a classical one for concerns of voltage insulation for transformer designers.
