The latest form of lightning arresters which involves an entirely new principle for protection against lightning, is that known as the Electrolytic or Aluminum Arrester. This arrester is used chiefly on high tension transmission lines. The above illustration is a cross section view of the device, the "inverted dishes" are called aluminum cones. Arresters of this type should prefer...ably be installed out of doors. Digitized by VjOOQIC 35 every overhead circuit connected with the station.
