Detección de Fallas en Transformadores de Medida de 150 kV

摘要

This paper presents a case study applied to five measurement transformers, in which potential failures were detected and were temporarily withdrawn from service, until a real failure of great magnitude to occur. The technique of case studies presented, has been used direct observation combined with the techniques of infrared thermography and dissolved gas analysis, identifying correlations, to finally raise a working hypothesis allow to generalize their application.
