Abstract
A method for deconvoluting a time dependent impedance spectrum and using the deconvoluted time dependent impedance spectrum as an indicator of the performance condition of a working fluid is disclosed. Also disclosed is a method to determine the viscosity ratio of a working fluid using the resistance ratio obtained from frequency dependent impedance data.
