Short-circuit current limiter based on TPSC

Increasing the ratings of equipment or even replacing them are not the best methods for solving the excessive short-circuit current, which is due to the increasing short-circuit capacity of transmission system. Adopting TPSC with externally linked series reactor, the short-circuit current limiter with its high reliability, availability, and its successive application to 500 kV substations in South California of USA, helps the FACTS technology break the fault current limitation in high voltage transmission system.
