Superconductors As Surge Current Protectors

Modern Power Systems are growing fast with more generators, transformers and large network in the systems. The installation, running and maintenance costs of the power system equipment are more. Whenever a fault occurs, there is a need for the protection of these systems. Power System Protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the isolation of faulted parts from the rest of the electrical network. Superconductors are one of the last great frontiers of scientific discovery. Here, in this paper we discuss the use of Super Conductors as protective devices for Surge Current Protection. Superconductors conduct electricity offering zero resistance below certain temperatures. We study different types of super conductor fault current limiters and their working.
