GRTU

Description

The GRTU is a compact Remote Terminal Unit (RTU) used to optimise the quality and the service in the electricity Networks.  It provides full remote control and command of the network/customer electrical MV cubicles. The GRTU is fully certified to ensure the compatibility and the interoperability with the existing DMS supervisory station, e.g. LYNX, for management and full control according to most of the international industrial communication standards. More than thousand GRTU units are currently in installation phase in Brussels (Belgium).

The  automatisation and  the remote control of the electrical MV cubicles optimise the quality and the service in the electricity Networks.

Dedicated to be installed in the electrical network/customer cubicles, the GRTU unit realizes the integration of the essential functionalities needed for distant control and commands.  The GRTU is a modular, compact and off-the–shelf unit.  It ensures the compatibility and the interoperability with the existing DMS  supervisory station, e.g. LYNX (*1) for management and full control according to the industrial  communication standards.
