The research on the electrical conductivity of the FDO oil (dioctyl phthalate) during the Joule heating, based on Joule's law, was realized. Attempt was made to heat the oil without its flow in a stationary heater, with plane parallel electrodes oriented horizontally. On the basis of an analysis of the experimental results obtained, it was found that the method employed to the Joule heating in the HV electric field applied to the electrodes, seems very efficient while heating the FDO oil. It was suggested that in higher temperature range the conduction mechanism is associated with the motion of the hydrocarbon complexes, whereas in the lower temperature range the conduction mechanism is controlled by the motion of the FDO oil impurities.
