The insulation between the lengths of duct and the insulation between each length and ground serve two purposes. One of these purposes is to prevent the eddy currents induced in a particular duct from circulating between that particular duct and the adjacent ducts and also between that particular duct and the grounded supporting structure for the ducts, thus preventing the undesirable heating which tends to result from such circulating eddy currents. The other of these purposes is to direct faults that occur to the duct to ground via a path extending through a ground return bus.
