Growing challenges
The energy market is changing. The previously unidirectional power flows from the high-voltage to the low-voltage network have changed with the legally promoted and ever-increasing decentralised generation and supply of energy. As a result, simple network monitoring is often no longer sufficient to ensure the stability of electricity grids. In addition, since it is almost impossible to expand the networks at a reasonable cost and time, they need to be adapted to the new challenges in a different way.
Intelligent supply networks as a way out
Modern telecontrol and substation automation technology enables the creation of intelligent supply networks. The combination of novel communication infrastructures with high security standards means that effective and efficient network management can be achieved. At the same time, the cost of commissioning and maintaining a system should not be ignored, especially in times of increasing cost pressure.
Makes efficient, tailor-made solutions possible: the series5
This is where the strength of the universal configuration tool SAE setIT comes into its own, allowing intuitive, convenient and therefore fast configuration and commissioning of the systems. The Lacroix SAE hardware components of the Series5 – FW-5, FW-50 and FW-5000 – are also optimally adapted to the requirements of the new focus on infeed management and local network automation. Together, these products provide a proven, reliable foundation for building high-quality, cost-effective solutions that, most importantly, meet your needs.

Renewable energies
The German government’s climate targets will require significant adjustments, not least to the existing infrastructure. Therefore, depending on the output of the plant, operators of decentralised energy resources (DER) must create the technical prerequisites for monitoring and controlling their plants. With this in mind, Lacroix SAE offers efficient, configurable telecontrol solutions.

Secondary Unit Substations (SUS)
The decentralised feed-in of renewable energy sources makes the monitoring and automation of local network stations increasingly urgent. Firstly, to ensure stable networks with reliable voltage and frequency bands. Secondly, to avoid costly equipment overloads. Lacroix SAE offers economical solutions that can be implemented in a short time.

Low voltage network monitoring
The use of SAE remote control technology in low-voltage measurement enables precise and reliable monitoring of power grids. By integrating intelligent communication systems, it ensures real-time data acquisition and efficient grid management. This technology enhances fault detection, optimizes energy distribution, and supports the integration of renewable energy sources. As a result, utilities can improve network stability and reduce operational costs.

Substation automation
Sophisticated functionality, a high level of performance and a long service life are features of all SAE’s telecontrol and substation automation solutions. To meet different requirements for monitoring, control and automation of supply infrastructures and industrial systems, we developed the series5: a product family with a common technical basis and specifically practice-orientated core services.
