Parallel-Resonance-Type Fault Current Limiter [PDF]
IEEE Transactions on Industrial Electronics, 2013 This paper proposes a new parallel-LC-resonance-type fault current limiter (FCL) that uses a resistor in series with a capacitor. The proposed FCL is capable of limiting the fault current magnitude near to the prefault magnitude of distribution feeder current by placing the mentioned resistor in the structure of the FCL. In this way, the voltage of the

Analysis of the DC Fault Current Limiting Characteristics of a DC Superconducting Fault Current Limiter Using a Transformer [PDF]
Energies, 2020 Recently, a lot of interesting research has been conducted to solve the fault current problem of the DC system. In long-distance transmission, DC transmission is more economical than AC transmission. The connection of power grids with a DC system can also better control the power flow and provide high stability.
