DC‐presaturated fault current limiter for high voltage direct current transmission systems

open access: yesHigh Voltage, 2021
The authors present a 500 kV real‐dimension DC‐presaturated fault current limiter (PFCL) with a steady‐state rated current of 2 kA for limiting large fault current of 8 kA with high rate of rise. These characteristics of the fault current can be a threat
