This paper investigates the impact of the installation of cable fault indicators in combination with pagers in the underground part of a medium voltage power distribution network, on this network's reliability indices. For this purpose, a brief description of the examined network, as well as a description of the methodology which determines the network data, is given first. Information about the devices...
The paper presents a collection of slides about network transformation that requires the evolution of multiple network layers in the same timeframe. Network usage is application driven, and there is a great deal of uncertainty in applications demand and user behavior. Operators face critical choices in network architecture and technology that can have great impact on their business goals. A unified...
Due to a wave of investment in the 1960's-70's, a large amount of switchgear in W-Europe is now 30-45 years old. The number of ageing phenomena is increasing, and indicates that for certain types the end of service-life is showing up. Theoretically then, the switchgear should be replaced. In practice, however, service-life extension can be an option to reduce the required investment cost. Minimum...
Third-generation (3G) wireless networks provide for both increased circuit-switched voice capacity and high-speed packet data capabilities which promise greater access to rich multimedia content delivered to handheld or mobile devices. New data-centric high-bandwidth services will evolve the backbone to a data/Ethernet-dominated network. With such an evolution, the problem facing wireless service...
