Description

technical field [0001] The invention relates to the technical field of discharge source location, in particular to a test frame for a discharge source location test. Background technique [0002] In the power system, partial discharge or spark discharge is a precursor to the aging and failure of insulating materials. At the same time, the high-frequency radiation electromagnetic waves generated by the discharge will also cause electromagnetic interference to transmission and distribution lines, communication equipment near substations, and TV broadcasting signals. . Therefore, in order to find the aging part of the insulating material early, avoid insulation failure and avoid interference to the surrounding electromagnetic environment, it is necessary to locate the location of the discharge source. [0003] However, the existing test device for the discharge source location method is not accurate enough for the verification of the location algorithm, and there is a large di...
