Nexans will welcome Oliver Sauerbach, project manager of the AmpaCity project at RWE, who will present the experience with the AmpaCity system where the worlds longest superconducting power cable has been integrated in a medium voltage grid infrastructure in the city centre of Essen in Germany.

Sterlite is also taking key initiatives in facilitating the transition of the power transmission industry towards high-end new age conductors that offer better operational efficiencies by enhancing ampacity (power carrying capability) and reducing transmission losses.
The disadvantages of these types of protection include inability to easily add or remove cables from trays, cost, long term resistance to the environment (UV exposure and moisture), ampacity derating requirements and maintenance issues.
You can think of it as a solar solution for the ampacity challenged.
Summary: At Middle East Electricity 2009, leading German company LIOS Technology will present its full range, including the very latest Distributed Temperature Sensing (DTS) systems and Real Time Thermal Rating (RTTR) solutions for ampacity predictions of energy transmission assets, including:
Using DTS, utility companies will be able to accurately monitor electrical capacity - known as Ampacity -- by using actual rather than estimated temperature data, enabling optimal circuit management.
He covers standard rating methods for power cables, and the thermal effects of ampacity reduction, cable crossings, thermal backfills, buried cables and real-time rating analysis, multiple cables in air, and pipe-type cables with slow dielectric fluid circulation.
Fuses used in a solar system must have high ampacity to resist arcing in a battery circuit.
When the current exceeds the rated ampacity of the electrical components, the inductor must be shut down and relined.
Ampacity on the line was increased by 121 percent, with a 36 percent reduction in weight, using only the existing structures.
Available features on the new electronic trip unit include two dials for simplified setup during installation, including an ampacity dial with seven ANSI ratings on each frame; tighter tolerances on protection curves from thermal magnetic breakers; a status indication light to provide user situational awareness; a test port for secondary injection testing; and a tamper-protection clear cover with a slot for a wire seal.
