Abstract :
In order to make the best decisions about managing the serviceability of a huge aged transformer population, it is imperative to understand the condition of the equipment. Functional-based methodologies that consider the assessment of the condition of transformer insulation on the relevant safety margins are discussed based on practical experience. Possible benefits of on-line diagnostic techniques and effective area of application of dielectric characteristics are presented
