Growing challenges
The energy market is undergoing significant change. The previously unidirectional power flows from high-voltage to low-voltage networks have shifted due to legally promoted and increasingly decentralised energy generation and supply. As a result, simple network monitoring is often no longer sufficient to ensure the stability of electricity grids. Moreover, since expanding the networks within reasonable cost and timeframes is almost impossible, they must be adapted to these new challenges in alternative ways.
Intelligent Supply Networks as a Solution
Modern telecontrol and substation automation technology enable the creation of intelligent supply networks. The combination of novel communication infrastructures with high security standards allows for effective and efficient network management. At the same time, commissioning and maintenance costs must not be overlooked, especially given the current pressure to reduce expenses.
Enabling Efficient, Tailor-Made Solutions: the Series5
This is where the universal configuration tool SAE setIT demonstrates its strengths, providing intuitive, convenient, and thus rapid configuration and commissioning of systems. The Lacroix SAE hardware components of the Series5—FW-5, FW-50, and FW-5000—are optimally adapted to the requirements of the new focus on feed-in management and local network automation. Together, these products form a proven and reliable foundation for building high-quality, cost-effective solutions that, most importantly, meet your specific needs.

Renewable energies
The German government’s climate targets will require significant adjustments, especially to existing infrastructure. Depending on the output of their plants, operators of decentralised energy resources (DER) must create the technical prerequisites for monitoring and controlling their facilities. With this in mind, Lacroix SAE offers efficient, configurable telecontrol solutions.

Secondary Unit Substations (SUS)
The decentralised feed-in of renewable energy sources increasingly demands monitoring and automation of local network stations. This is essential first to ensure stable networks with reliable voltage and frequency levels, and second to avoid costly equipment overloads. Lacroix SAE provides economical solutions that can be implemented quickly.

Low Voltage Network Monitoring
Using 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, high performance, and long service life characterize all SAE telecontrol and substation automation solutions. To meet the diverse requirements for monitoring, control, and automation of supply infrastructures and industrial systems, we developed the Series5: a product family with a common technical foundation and specifically practice-oriented core services.
