“…Two voltage taps were attached to one coated conductor to measure the AC loss; a lead loop for the voltage taps was wound spirally around the entire mono-layer conductor. The AC loss energy of an entire mono-layer conductor per unit length per cycle is obtained as (5) where is the distance between the voltage taps, which is 100 mm in the samples;…”

AC losses in power transmission cables composed of coated conductors could be potentially small. A strategy to approach their potentially small AC loss was studied. AC losses in mono-layer conductors for cables were calculated numerically in order to show the principle for AC loss reduction: use of narrower coated conductors and/or decrease in space between conductors reduce the magnetic field component perpendicular to the wide face of coated conductors, and they are effective for AC loss reduction. This principle was confirmed experimentally by using short monolayer conductors. Based on the principle, 1 kArms-class three-layer conductors were fabricated, and AC loss of 0.054 W/m at 1 kArms was achieved in a three-layer conductor whose outer diameter is 19.6 mm. The influence of a magnetic substrate on the AC losses in a single coated conductor and a mono-layer conductor for a cable was studied numerically.

“…Over the last few years, high temperature superconductors have matured, especially due to the technical progress achieved in the manufacturing of these materials, and are now on the verge of industrial scale production. Furthermore, several superconducting cables [1][2][3][4][5] as well as superconducting fault current limiters [6][7][8] for power systems have been tested during the last years in real grid applications worldwide and are now on the threshold of commercialization. The experience gathered in these tests shows that all technical requirements are fulfilled so far and a high reliability of these new power devices can be achieved.…”

In recent years significant progress has been made in the development of high temperature superconducting (HTS) power devices, in particular cables and fault current limiters. Several field tests of large scale prototypes for both applications have been successfully accomplished and the technologies are getting closer to commercialization. In this paper the German AmpaCity project will be introduced and its objectives will be described. Furthermore, the conceptual design of the HTS cable system and the major developments which have been achieved so far, as well as the current status of the project will be reported.
