OnixSat and Inmarsat developed a solution based on satellite connectivity to enable Cemig to increase availability and improve its remote controlling of reclosers.
Sandro Bernardes Oliveira, a telecommunications engineer at Cemig, commented: “The solution was specified by the Management of Telecommunications Solutions and Maintenance, in partnership with the Management of Distribution Assets Automation, and uses a serial/ ethernet converter and Inmarsat’s BGAN 9502 terminal to connect the reclosers to Inmarsat’s ultra-reliable L-band satellite network, in order to ensure the effectiveness of the commands issued to the reclosers by Cemig’s Centre of Operations.”
The Inmarsat satellite communications network has been crucial for assuring connectivity, reaching reclosers in very remote locations in the Cemig distribution network. Its coverage enables Cemig’s field equipment to send and receive data regardless of its location, and its 99.9% uptime ensures that they will always remain connected, even in adverse weather conditions.
With the BGAN terminal to install, and without a complex terrestrial infrastructure to deploy, the solution is easy to configure. Cemig’s technicians do not need to have an advanced knowledge of communication via satellite to implement the solution, because it is very easy to establish a connection with the Inmarsat satellite network.
