We have developed a method which might prove useful for studying the properties of ions in viscous liquids. Results obtained with an “Esso” transformer oil of 0.33 poise viscosity at room temperature are given to illustrate the method.
As a result of the extensive studies of high-field conduction and flashover in dielectric liquids it is becoming clear that the mechanism of electrical breakdown in such materials is related to the pre-breakdown charge flow. At present it is not known whether the current gives rise to significant heating such that failure occurs due to a thermal run-away1 or whether space-charge accumulation due to...
The current-voltage d.c, characteristics of several saturated acyclic hydrocarbons (n-C5H12, n-C6H14 and n-C6H16) have been studied in a coaxial electrode arrangement previously described and providing a high field-gradient between the inner (thin wire) and the outer electrode. The liquids were tested after various stages of purification, and under both polarities of the cell. Before any measurement...
