Tapping tools
Abstract:
Electric power may be tapped straight from the high voltage transmission lines either for consumption to meet the needs of rural and remote areas, and telecommunication establishments located in remote sites; or as a scheme to enhance the capacity of another utility or grid along a trans-national or trans-continental transmission corridor. The importance and interests the technologies to accomplish this has generated necessitate the need for a review of the state of the art of this subject so as to delimit research actions and allow research interests to be appropriately promulgated. In the first part of this work the principle, conditions and methods for tapping from HVAC lines have been discussed. This paper completes the study by looking at tapping from the HVDC transmission systems. The principles on which tapping methods from HVDC system is based are presented; and various methods, existing and novel, for multiterminal operation or integrating small tapping into HVDC links are reviewed. The paper ends with a general discussion of tapping from HVDC, and concludes with a presentation of the future direction.
