A Framework For Asset Management in Electrical Systems, Part II: Case Study - Power Transformers

摘要

This document presents a case of study where the methodology presented in the part I is applied. Hence, the managing engineering life cycle in power transformers for short, medium and long term is assessed. The first section presents both the modeling and dynamic estimation of temperatures in transformers for short-term management. The next section presents the model to estimate the health condition, which is used to calculate the risk index in medium-term management. The last section describes the methodology to estimate the remaining life of power transformers in order to quantify the opportunity index of strategic assets is addressed. Finally, results to apply the methodology to two power transformers belongs to the local utility ENEL-Codensa S.A – ESP are presented.
