Experimental validation of magnetic shield type fault current limiter circuit model

A circuit scheme of a Magnetic Shield Type Superconducting Fault Current Limiter is developed. The circuit parameters are determined by means of the energy conservation law after the discretized field problem inside the device is solved. In order to validate the model a basic prototype of the limiter is tested. Experimental and numerical waveforms of current and voltage across the device under different operating conditions are compared. The equivalent circuit obtained can be introduced in a power system simulator to evaluate how a Magnetic Shield Type SCFCL interacts with a power network.
