Communication between MV UPS and MV Switchgear

There is a high-speed optical communication link between the MV UPS's system controller and the
switchgear. The purpose of the link is to read and write information from/to the I/O modules installed in
the MV switchgear. The breakers' status, current, voltage, and commands (open/close) to the circuit
breakers (S , S , S ) are transmitted through fiber optic.
