Superconducting Fault Current Limiter

, 2018
The superconducting fault current limiter concept explains two types of superconducting materials firstly resistive SFCL, Secondly, Inductive-SFCL. We also study some applications of SFCLs which is used to limit the fault - current that occurs in power system.

A novel concept of fault current limiter based on saturable core in high voltage DC transmission system

AIP Advances, 2018
To develop mechanical circuit breaker in high voltage direct current (HVDC) system, a fault current limiter is required. Traditional method to limit DC fault current is to use superconducting technology or power electronic devices, which is quite ...
