ABSTRACT:
A method and means of monitoring the quality of a fluid dielectric capacitor by measuring the Kerr signal of a dielectric fluid which has the desired dielectric and breakdown properties and continually measuring the Kerr signal of the same fluid dielectric while in use to determine if there is any degradation of the fluid in use. The means for measuring the Kerr signal is by projecting a high intensity light beam such as from a laser source through the dielectric fluid of a capacitor between two of the plates and detecting the amount of light passed through the dielectric which is an indication of the condition of the dielectric liquid.
