Abstract

This paper is aimed at presenting the fundaments towards a computational methodology to assist in the establishment of electro-electronic device performance analysis of consumers refunding. The strategy is based on the calculation of appliance dielectric and thermal stresses with different power system disturbances. Such strategy consists on a first orientation to support studies, analysis and reports about the decision of refunding consumers in such a complex subject. The approach is based on a time domain modeling and computational implementation of different electronic devices and power network elements into the ATP program to simulate the power system disturbances and the equipment performance. In this work, a typical TV device is taken to illustrate the proposed methodology. The dielectric and thermal stresses here considered are related with the occurrence of voltage swells, oscillatory transients and high-frequency impulse related to lightning strikes.
