Abstract
An improved triggered arc flash arrester includes a shield apparatus disposed within an interior of an evacuated envelope and includes a first shield element and a second shield element. A plurality of conductors are partially disposed within the interior and are separated from one another by a gap. A first element of the shield apparatus is situated adjacent the envelope and is structured to protect the envelope from damage due to the high temperature plasma that results from an arc across the gap. A second element of the shield apparatus is interposed between the gap and at least a portion of the first element and is structured to protect the at least portion of the first element from damage due to an arc across the gap.
