FACTS
FACTS systems are used to flexibly and rapidly regulate power flow, voltage and system stability in AC transmission networks. They increase the transfer capacity of existing grids, improve network stability, and reduce losses and disturbances. Different types of air‑core reactors are used depending on the system.
