GRTU – Smart Grid
Description
The GRTU-SG is a modular automate intended for supervision and control of medium and low voltage electrical networks (MV/LV).
This automate allows a complete supervision of a MV/LV distribution substation.
Its modular design offers you the possibility to adapt its functionality to each specific need of a distribution substation within a single and same enclosure.
The GRTU-SG brings new solutions to operators to improve the network’s energy efficiency and brings solutions to distributed power generation issue (Photovoltaic, wind power, …)
The GRTU-SG supports modern communication channels such as Ethernet, GPRS, …
