A computational approach for consumers refunding analysis due to equipment damages

This paper presents a computational strategy proposal for the analysis of refunding requests for damages. The activities involve studies and modeling of typical power distribution system, some electromagnetic disturbance phenomenon and a variety of household, commercial and industrial electro-electronic devices. Based on the discretization of the voltage and current waveforms resulting from the non-ideal operating conditions, this work shows a procedure to correlate the disturbances occurred in the networks with the dielectric and thermal stresses applied to the considered devices. These indicators are sequentially confronted with the focused equipment withstand capability limits so as to verify the possibility of damages. By applying the approach to specific studies the overall method and software utilization is highlighted. The results show good consistency regarding the emission of a judgment on the subject discussed here.
