Abstract
Complex studies have led to the development of powerful methods to assess the health of the insulation system, and even the entire transformer, by periodically analyzing samples of the transformer oil. By far the most important of these diagnostic methods is dissolved gas analysis (DGA), which was introduced in the 1960s. Our ability to measure and interpret the dissolved gases has improved tremendously over the last 50 years.
