There are no 'powers of Orders' conferred on Deacons. They are authorized to assist the priest at the Altar,  proclaim Word and to do the works of Charity. Pope Paul VI made this abundantly clear in his 2009 Motu Proprio, "Omnium in Mentem." 
There is no Sacramental ordination to Diaconate. Granny Smith is doing it all as we chat.
