Therefore there is an urgent need to limit the fault current
levels because of which the installed circuit breakers are
interrupting currents out of their rated breaking capacity
as a consequence of which they are bursting. Until now,
many devices such as split bus bars, transformers with higher
impedance, and fuses have been used in industry to reduce the
peak value of fault currents. However, the use of these devices
has limitations, in that they can damage the reliability of the
power system or increase power loss . SFCL presents an attractive prospect in limiting the fault current very effectively
without additional power losses during normal operation and
at the same time improving the transient stability of the
system.
