Abstract
An isolation transformer is introduced into a matrix fault current limiter (MFCL) and is used to couple elements in trigger matrices and current limiting matrices. The isolation transformer can either be a voltage step-up or step-down configuration. In step-up configurations, the increased voltage supplied to the current limiting elements improves the quenching of the superconductor. In step-down configurations, current limiting elements are subject to lower voltage potentials thereby reducing the electrical insulation requirement between the trigger matrix and the current limiting matrix. In addition, the voltage amplification coefficient of each isolation transformer can vary for different columns of the current limiting matrix to maximize the current limiting performance.
