dielectric (adj)

A capacitor stores electrical charge (and thus also electrical energy) and comprises two conducting surfaces separated by a dielectric.

Electrical discharges (sparks) travel from an electrode (tool, usually positive) to the workpiece, which is separated from the electrode by a non-conductive medium, the dielectric fluid (oil, deionised water).
