The system, designed to be installed on the secondary side of the power transformer and on low-voltage feeder lines, integrates several key components: the SBT4V-5C Low Voltage Supervisor, the SBT-TDM network Analyzer, the SBT-VTN Neutral Voltage Monitoring, and the SBT-CDS Data Concentrator. Its architecture enables the acquisition of critical data from both the transformer secondary and feeder lines, providing a comprehensive view of the low-voltage network’s performance.

With this solution, utilities and network operators can significantly improve line energy balance, phase balance, power quality monitoring, and fault or anomaly detection—including issues such as technical losses, theft, or tampering.

In a context where advanced low-voltage monitoring is considered a key factor in the transition towards smart grids, SACI takes the lead.

Within this architecture:

• SBT4V-5C collects and analyzes the main electrical parameters of the three-phase network, detecting imbalances, overloads, or transformer anomalies and transmitting data to remote systems.
• SBT-TDM monitors key electrical parameters at the transformer’s output lines, offering a detailed view of network status and power quality.
•   SBT-VTN, the neutral voltage monitor, ensures system safety and reliability by detecting insulation faults, current leakages, or defective connections.
•  SBT-CDS, the data concentrator, enables real-time monitoring, detection of energy losses, and optimization of power quality.

The implementation of this system not only improves operation and maintenance, but also helps to reduce costs, outages, and risks, providing reliable real-time supervision of low-voltage circuits. This solution supports regulatory compliance, lowers operational expenses, and optimizes predictive maintenance and diagnostics of electrical infrastructures.

With this initiative, SACI reinforces its commitment to digitalization, sustainability, and energy efficiency, offering utilities, industries, and infrastructure managers a strategic tool to face the challenges of the low-voltage networks of the future.
