Description

technical field [0001] The invention relates to a suspension discharge test model suspension discharge detection and positioning device and method, in particular to a suspension discharge test model suspension discharge detection and positioning device with high detection sensitivity, high accuracy, multiple detection methods, and mutual verification of detection results The invention and the method belong to the technical field of partial discharge simulation model. Background technique [0002] Under normal circumstances, the insulation performance of power equipment operating in the grid can withstand the operating voltage. Due to the influence of manufacturing and installation processes, there may be bubbles, impurities, cracks, etc. inside the insulation of electrical equipment. Under the action of high-voltage alternating electric field, the electric field strength inside or on the surface will be too high, and periodic partial discharge will occur inside the insulatio...
