Abstract :
The state of water in insulating oils was studied using infrared ray spectroscopy. It was found that there are many kinds of water clusters in the materials: monomer (H2O), dimer(H2O)2, trimer(H2O)3, and polymer(H2O)n. Under electrical stress, the states of water were changed by applying different electrical fields. The dimer state had no effect on the conduction, whereas trimer contributed to the conduction when the water content was higher
