Methods and systems for managing dielectric properties of a pulsed power drilling fluid are provided. In one embodiment, the methods include introducing a drilling fluid into a drilling pipe that extends into a portion of a wellbore; separating the drilling fluid into a solids rich portion and a solids lean portion in the drilling pipe at a location proximate to a pulsed power drill bit; allowing the solids lean portion of the drilling fluid to flow through the pulsed power drill bit; and drilling at least a portion of a wellbore. In some embodiments, the methods and systems include passing the drilling fluid through one or more hydrocyclones. In some embodiments, the methods and systems include passing the drilling fluid through one or more centrifuges.
