Supervision of electric sub-station development by Armadeus Systems

The project

Our Client wanted a system to supervise its electrical transformation stations in order to reduce maintenance costs and increase service quality, while reducing the risk of breakdowns.

A number of sensors (temperature, humidity, light, acceleration) were installed in order to anticipate potential transformer failures and limit the number of maintenance visits.
In addition, Industrial Inputs/Outputs were able to control actions on the system.
The unit is able to communicate securely (encryption) and remotely with a monitoring server, either through ADSL or by connection to the cellular network.
