Method and system for surface discharge test electrodes for simulating slightly non-uniform electric field conditions

The invention discloses a surface discharge test electrode method and system for simulating slightly non-uniform electric field conditions, and the method comprises the steps: extracting a surface structure of a to-be-researched region according to the overall structure of electrical equipment; according to the surface structure, calculating an electric field component of the to-be-researched region and an electric field non-uniform coefficient of the surface region; designing a test electrode of which the size is the same as that of the creepage structure of the to-be-researched area; calculating a surface electric field component and an electric field non-uniformity coefficient of the test electrode according to the surface structure of the test electrode; and according to a preset test electrode effectiveness discrimination formula, comparing the electric field components of the to-be-studied area and the test electrode with the electric field non-uniform coefficient of the creepage area, and according to
