SEG Electronics offers line differential protection with fiber optic communication, because it is the best way to protect an overhead line or cable. Speed is important for differential protection because it is the most selective protection. Since communication between the devices occurs via fiber optic connections, data transmission is extremely safe.

Our relays offer a wide range of protection and supervision elements. Integrated recorders and logging functionality assist the user in detecting transformer aging and analyzing failures.

Enhanced communication capabilities are the basis for the integration into automation systems.
