Claim 1
Independent Claim
113 words
A METHOD OF MEASURING THE VOLTAGE OF A HIGH VOLTAGE SOURCE, WHICH COMPRISES: (A) MEASURING THE FLOW OF ELECTRIC CHARGE THROUGH AN ELECTRICAL CONDUCTOR, SAID CONDUCTOR BEING IN HEAT EXCHANGE RELATIONSHIP WITH A NON-FLOWING DIELECTRIC LIQUID, (B) IMPOSING A NON-UNIFORM ELECTROSTATIC FIELD IN SAID DIELECTRIC LIQUID IN THE VICINITY OF SAID CONDUCTOR WITH SAID HIGH VOLTAGE SOURCE WHEREBY THE RATE OF TRANSFER OF HEAT FROM SAID CONDUCTOR TO SAID DIELECTRIC MEDIUM IS CHANGED, AND (C) MEASURING THE FLOW OF ELECTRIC CHARGE THROUGH SAID CONDUCTOR AFTER THE IMPOSITION OF THE ELECTROSTATIC FIELD IN ORDER TO DETECT THE CHANGE IN FLOW OF ELECTRIC CHARGE RESULTING THEREFROM AND THEREBY DETERMINE THE VOLTAGE OF SAID VOLTAGE SOURCE.
