Landis+Gyr SGP+M

SGP+M is a system developed by Landis+Gyr and running in Brazil (and potentially other countries), it stands for Sistema de Gestão de Perdas e Medição (System for Management of Losses and Metering). It is divided into Primary Concentrators (Concentrador Primário or CP) and Secondary Concentrators (Concentrador Secundário or CS).

Note that I don't access to the hardware described here. All of my research was done through observation and research.


Known Operating Locations

  • Rio de Janeiro, Brazil


Metering Module

Metering Module

The Metering Module (Módulo de Medição) is installed inside the CS, each utility client has one dedicated to them (or 2/3 if they have a two-phase or three-phase system).

This module has a built-in smart meter system, contactor for remote shutdown, and a phototransmitter and photoreceiver for communication with the CS computer.





Secondary Concentrator

Secondary Concentrator

The secondary Concentrator houses 12 Metering Modules, a CPU/Radio (metal box on the right) and a main MCCB. The Metering Modules talk with the CPU through a shared optical interface. The CPU contains the software/harwdare to communicate with each meter and a built in radio that communicates with the Primary Concentrator through some proprietary FHSS stuff briefly mentioned in the manual.
