The invention discloses an electrode system for composite dielectric interface quadrature electric field measurement. The electrode system for composite dielectric interface quadrature electric field measurement comprises an electrode system used for providing a vertical electric field or a quadrature electric field for a composite dielectric interface during a test process; and a pressure control system used for continuously providing required interface pressure for the composite dielectric interface during an electric field exerting process and measuring the pressure exerted on the composite dielectric interface during the test process. Rotary nuts on rotary screws are used for adjusting pressure exerted on the dielectric. Researches on various electrical performances of the composite insulating dielectric in different pressure conditions are realized. Aluminum foil electrodes are attached to an interface. One end of a high-pressure electrode aluminum foil is made to contact the positive electrode of a high-pressure aluminum cylinder while the other end is placed on the insulating composite interface and well pressed. One end of a grounding electrode aluminum foil contacts a grounding electrode while the other end is placed on the insulating composite interface and well pressed. A quadrature electric field is thus provided for the insulating composite interface. Simulation of real electrical characteristics of real cable joints and the cable composite insulating interface is then achieved.
