Técnicas para el diagnóstico de transformadores de potencia: Una revisión crítica

Abstract

Power transmission systems involve an essential relationship in the productive and social sectors of a country. The power transformers are one of the main components in the power systems; these systems allow exporting energy in high voltage over long distances. Failure of a power transformer can lead to a partial or total collapse of an electrical system. There are several procedures for maintenance and diagnosis of such equipment. In this paper, a critical review of eight of the main diagnostic techniques of power transformers is made, including its description and historical evolution, taking into account that currently, those methods can be applied online or those that probably will be applied.
