Abstract
A high-voltage electrical connector includes a strategically placed barrier that acts as an arc shield to reduce the ionization of materials during load break switching, reducing or preventing flashover. An electric stress graded interface design also reduces switching flashover and reduces the fault close energy. Mating features on the piston-contact element and inside the surrounding container accurately guide the piston-contact element as it travels along the container.
