This invention provides a method for removing dibenzyl disulfide, which can remove dibenzyl disulfide from an insulating oil to be injected into an electrical equipment at room temperature with a compact apparatus. The method comprises a dibenzyl disulfide removing step of bringing an insulating oil to be injected into an electric equipment into contact with an adsorbent, which adsorbs dibenzyl disulfide at room temperature, to remove dibenzyl disulfide contained in the insulating oil, and an insulating oil injection step of injecting the insulating oil, from which the dibenzyl disulfide has been removed, into the electric equipment. Cette invention porte sur un procédé pour retirer du disulfure de dibenzyle. Le procédé permet de retirer du disulfure de dibenzyle d'une huile isolante à injecter dans un équipement électrique à température ambiante à l'aide d'un appareil compact. Le procédé consiste à retirer le disulfure de dibenzyle en mettant une huile isolante à injecter dans un équipement électrique en contact avec un adsorbant qui adsorbe le disulfure de dibenzyle à température ambiante ce qui élimine le disulfure de dibenzyle contenu dans l'huile isolante ; et à injecter dans l'équipement électrique de l'huile isolante de laquelle a été éliminé le disulfure de dibenzyle.
