Abstract (en)

[origin: EP0246820A2] A pad-mounted electrical distribution transformer (10) including an electrically grounded tank (12), an electrical element in the tank, and a draw-out surge arrester assembly (200) which extends into the tank. The draw-out surge arrester assembly includes a housing (202), and a draw-out device (204) removably disposed in the housing. The draw-out device includes a fuse (292) connected in series with the surge arrester, between the electrical element and grounded tank, with the fuse being sized to isolate the surge arrester from the electrical element, should the surge arrester fail to recover properly from a voltage surge.
