Method of measurement of partial capacitances for tested objects with three electrodes

The article is devoted to the development of a method measuring partial capacitances between electrically conductive structural elements capacitive tested object with three electrodes. developed involves applying resistive-capacitive grounding investigated insulation layer subsequent gradual adjustment value auxiliary resistor, through which grounded, at phase shift voltage on and capacity will be equal 0º. results calculations showed that in this case electrodes depends only circuit, does not depend electrical resistance caused by dielectric losses. After voltages substitution scheme followed similar re-adjustment for different capacitor, it possible form system equations, solution allows you determine unknown values capacities layers. can used each capacitance control require use 3-terminal immittance meters application-based cumulative measurement survey techniques
