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