Abstract

High-power short-circuit test results and numerical simulations of a 15kV–24MVA distribution-class High Temperature Superconductor (HTS) Fault Current Limiters (FCL) are presented and compared in this paper. The FCL design was based on the nonlinear inductance model here described, and the device was tested at 13.1kV line-to-line voltage for prospective fault currents up to 23kArms, prior to its installation in the electric grid. Comparison between numerical simulations and fault test measurements show good agreement. Some simulations and field testing results are depicted. The FCL was energized in the Southern California Edison grid on March 9, 2009.
