Abstract

Superconducting fault current limiters (SCFCLs) are expected to improve the reliability of power systems. An SCFCL of a transformer type with adjustable trigger current level was proposed. Three SCFCLs of this type for 3-phase AC power source were designed and made. The trigger current level of each trial SCFCL can be adjusted to equal value, and the SCFCLs can be used as a 3-phase SCFCL. As preliminary tests, sudden-short circuit tests with a 20 kVA synchronous generator are carried out. Limiting tests of the 3-phase SCFCL at fault are carried out with the synchronous generator. The effect of 3-phase SCFCL and the characteristics of the synchronous generator are studied experimentally
