Title: Method for on-line monitoring of condition of non-aqueous fluids

Abstract: A method for determining a condition of a highly resistive fluid in transportation and industrial equipment. The method is suitable for determining the condition of a non-aqueous fluid including applying a high-frequency voltage signal between electrodes immersed in the fluid, measuring the fluid's response to the applied signal and determining a fluid property, and comparing the magnitude of the determined property, relative to the magnitude of that property when the fluid is fresh.
