Abstract :
The impact of flow electrification in transformers is highlighted, using experimental studies on pressboard pipe models and a multilayer sectional model of a 400 kV transformer. The need for an analytical approach to calculate the potential distribution under actual flow conditions is discussed. The development of a computer program and its application to predetermine the electric stresses in oil-paper interface are described
