    Abstract: A method for determining quality and condition of a highly resistive fluid in transportation and industrial equipment. The method applies a multitude of oscillating voltage signals at determined frequencies and offsets to electrodes immersed in the fluid and quantifies fluid response to the signals. The method monitors response of the fluid to a preferred three fixed electrical signals applied a high and a medium frequency signal with zero offset voltage and a low frequency signal with an offset voltage. For fluids in applications where change in the fluid's change in high-frequency response is substantially less than changes in medium- and low-frequency responses, the method can monitor response to only the medium-frequency, zero-offset- voltage signal and the low-frequency, non-zero-offset-voltage signal. The magnitude and rate of change of fluid responses, relative to initial or peak values, are used to essentially continuously determine fluid quality and condition while in use.
