Distribution Automation Terminals
GP3415
The GP3415 integrates line protection and communication equipment management in a modular plug-in chassis with flexible configuration and independent protection modules. It is suitable for substations, indoor and outdoor switching stations, distribution rooms, disconnector rooms and box-type substations.
Collects, processes and analyzes real-time distribution-network measurements and remote-signaling data so the dispatch center can monitor network conditions and make operating decisions. Remote control enables equipment operations from the control center, shortening fault-handling time and reducing labor intensity.
