METHOD FOR DETERMINING THE CONDITION OF A NON-AQUOUS FLUID AND APPLIANCE COLLECTING REQUIRED DATA FOR MONITORING AND DETECTION OF A FLUID CONDITION A method for determining the condition of a highly resistive fluid in transport and industrial equipment is presented. The method is suitable for determining the condition of a non-aqueous fluid comprising: a) applying a high frequency voltage signal between electrodes dipped in the fluid, b) measuring the fluid response to the applied signal and determining a fluid property, c ) compare the magnitude of the property determined relative to the magnitude of that property when the fluid is new to at least one property limit and compare the rate of property change determined as a function of a use variable with at least one rate, resulting in the determination of fluid condition where each step is conducted continuously, intermittently, repeatedly and in combination es thereof; and wherein the frequency is in the range of about 10kHz to 10 MHz.
