Modern . power system are growing fast with . more generators. , transformers and large network in the system. whenever a fault occurs there is a need for the protection of these system. Here we discussed the use of superconductor as protective device for surge current protection. Superconductors conduct electricity, offering zero resistance below certain temperature. We study different types of superconductor as fault current limiter and their working. By. J DAVID MANOHAR. (. 08A31A0232). NECESSITY OF SUPERCONDUSTOR.
