摘要：
This electrical tree test method is a method for testing for electrical trees in an insulating member including mica insulation provided around an electrical conductor, and comprises: an assembly attaching step (S03) for attaching an electrode setting assembly to the outside of the mica insulation; an impregnation step (S04), after the assembly attaching step, for impregnating the mica insulation with synthetic resin; a removal step (S05), after the impregnation step (S04), for removing the entire electrode setting assembly except an electrode structure; a power supply connection step (S06), after the removal step (S05), for connecting the conductor and the electrode structure to a power supply in order to apply a voltage between the conductor and the electrode structure; and a voltage application step (S07), after the power supply connection step, for applying a voltage between the conductor and the electrode structure.
