PDF nderstanding Water in Transformer Systems

water in transformer oil has been re-introduced over the past 15 years. The concept of relative saturation of water in transformer oil is not a new one and was originally championed by Frank Doble as early as the mid 1940s.Thus, this article discusses and details the relationship between RS and ppm.
