Fault current limiters (FCLs) of 5000-15000 A holds the largest market share, owing to their large scale application in power transmission and distribution (T&D) utilities, manufacturing sectors, and railway. Thus, these FCLs can protect the grid from excessive fault currents when the load is large and make it easily stable, protect sensitive equipment, and minimize overall downtime in large-scale power networks.
To control these high, short-circuit currents, T&D utilities and manufacturing industries use a class of FCLs of 5000-15000 A that protect transformers, switchgear, and circuit breakers by preventing electrical faults from reaching them.
