(Summary description)In order to meet the judgment current requirements of the anti-electric test, it is mainly started from reducing the insulation capacitance of the transformer. The following points can be taken:
1) Increase the insulation thickness between the transformer windings and between the windings and the core.
2) Use insulating materials with low dielectric constant.
3) To prevent the transformer from getting wet, choose materials with low water absorption.
4) Double-layer or multi-layer shielding is adopted to reduce the capacitance between groups.
