Abstract

In this paper we present a new arrangement implementing a novel self-limiting transformer. We have developed a 1-phase model. We used a 3-limb transformer for one phase and we surrounded 2 limbs of the three, the primary and the secondary coils, with a common perfect closed YBCO loop. In this way we could realize the active magnetic short circuit which gives a new possibility for novel applications. Its operation is based on the principle of the magnetic flux conservation in a closed loop. This is a well-known physical law but so far not applied in this way. We used perfect closed YBCO wire loops with parallel turns. The paper presents the results of our experiments and opens new advanced applications of the perfect YBCO loops made of HTS wire. We considered the efficiency and significance of the perfect closed loop made from YBCO wire.
