This paper reports the findings of a novel approach to the study of the growth of water tree structures in silicone fluid under electric stress. Fibres of different types of materials were attached to a plane earthed electrode immersed in an aqueous salt solution. A layer of silicone fluid, floating on the water contained a point electrode to which high voltage was applied creating an asymmetric electrical field, in the liquid, terminating at the fluid/water interface. The frequency of the applied voltage was varied from 25Hz to 14kHz. The ionic content of the water at the bottom of the test rig beneath the fluid was also varied by dissolving different types of salts in it. Efforts were made to find the maximum rate of growth of the water tree structures. The frequency of the applied voltage had a definite influence on the formation of water trees, as did the type of ions in the water.
