TESTING THE OPERATION OF HIGH <I>T<sub>c</sub></I> SUPERCONDUCTING FAULT CURRENT LIMITER IN A REAL SYSTEM
Abstract
This paper presents the effects of an inductive type high-temperature superconducting fault current limiter (HTS FCL) on a three-phase system have been investigated both theoretically and experimentally in the case of a shunt and a subsequent series fault. Calculations have been performed for different cases including those when currents in the faultless phases would increase. This may lead to an incorrect operation of the automatic protection elements even in the faultless phases. The calculations based on the method of symmetrical components. To investigate the real physical processes, a measuring instrument was constructed to measure the transients due to the fast acting HTS FCL.
