Abstract

CERON, Andrés F; ORDUNA, Iván F; APONTE, Guillermo  and  ROMERO, Andrés A. Overview of Asset Management for Power Transformers. Inf. tecnol. [online]. 2015, vol.26, n.3, pp.99-110. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642015000300014.

This article presents an overview of the conceptual framework related to the asset management of power transformers, and to the assessment of risks associated with transformer failures. The risk index is an essential tool for developing the management of this asset, especially because it supports the asset manager in the decision-making process. The risk index is composed by two indicators: i) consequence factor, which assesses the impacts that could arise in the event of equipment failure, and ii) the probability of failure, which is determined from the results of tests for transformer functioning, operating history, and failure history, among others. General aspects of asset management according to international standards are presented, to then deal with specific aspects related to evaluation of the transformer risk index, found in the literature.

Keywords : power transformer; asset management; risk index; laboratory tests.
