Radio remotely controlled system of electric network subsidiary, Tg.Mures Romania - realizations and prospects

The authors describe how, during the last decade, 20 kV remote radio-controlled power system utilization has become indispensable for Romanian electric utilities. The system will be extended in the future, in a combined configuration, including either reclosers or switch-disconnectors. The used reclosers have to be introduced in existing remotely radio controlled systems. As reliability is absolutely necessary in secure radiocommunication support, the authors were recommended a 450 MHz frequency trunking communication system. Decentralization of the remotely controlled system, accorded autonomy of the territorial distribution maintenance center of SD Mures. (5 pages)
