    Power transmission of high-voltage direct current (HV dc) by overhead lines presents a new concept with which the industry has had little experience. Radio noise and corona loss values were recorded on a full-scale test line and statistically analyzed in relation to prevailing weather conditions. Comparison was made to radio noise readings taken on a nearby ac line. Results cover the analysis of a... View full abstract»

    For termination of rubber-insulated cable, it has been found practical to simply expose the factory insulation between stress cone and terminal for uncontaminated outdoor locations. In severe contamination exposure, however, the factory insulation surface and conventional tapes have been found susceptible to deterioration from leakage-current, resulting in tracking and subsequent flashover.

    An induction machine, fitted with two independent sets of windings on the stator, and two suitably interconnected sets of rotor windings, can be used as a variable speed machine in which the slip power from the rotor circuits is transferred by induction to one set of stator windings. From these it can be returned to the supply via a low power frequency converter which handles slip power only. View full abstract»
