Description

technical field [0001] The invention belongs to the technical field of space charge measurement using an electroacoustic pulse method, and in particular relates to a multipurpose high-voltage electrode for space charge measurement. Background technique [0002] As a key component of electrical and electronic devices, insulating media have electrical and aging properties that directly affect the reliability and life of equipment. Studies have shown that space charge is an important factor causing polymer electrical aging, which can directly reflect the degree of polymer electrical aging, mechanism damage, trap density and its distribution. Especially for organic media used in radiation environments, high-energy rays will lead to rapid degradation of media performance and shortened life, which in turn affects the operational reliability and life of electrical equipment and vehicles. Electrons of various energies are the most important radiation sources that lead to electrific...
