Low Voltage networks Portable Advanced Monitoring with the DNA Solution

New Challenges Faced by Electric Utilities

Low Voltage (LV) networks are undergoing a rapid transformation driven by the energy transition, the electrification of demand, and the integration of distributed generation. This context presents new challenges for electric utilities, which must reduce energy losses, improve operational efficiency, ensure supply quality, and optimize infrastructure planning.

In this scenario, real-time monitoring and advanced data analytics become essential tools for proactive, safe, and efficient network management.

LV DNA: a Portable Solution for Low Voltage Network Digitalisation

The LV DNA solution from Merytronic, combined with advanced analytics from the Ariadna Smart IoT platform, offers an effective response to these challenges. It is a portable monitoring device specifically designed to provide a detailed and accurate view of the behavior of LV networks—without the need for major investments or fixed monitoring infrastructure.

With its compact, rugged, and autonomous design, LV DNA enables rapid field deployment, capturing real-time data and transmitting it remotely via cellular communication. It complies with IEC 61010 CAT IV 600V and EMC 61326 safety standards, making it suitable for installation at any point in the LV network with full confidence.

Key Technical Advantages of LV DNA

Portability: Enables targeted monitoring of specific areas of the network without requiring permanent installations. Ideal for temporary interventions or diagnostic campaigns.
Compact, Autonomous Device: No external components needed. Includes connectors for voltage and current measurement, screen, LEDs, Ethernet, Bluetooth, GPS, and 2G/3G/4G cellular modem.
Simultaneous Monitoring: Can supervise up to 8 lines simultaneously (including the service line), thanks to 8 sensor connection ports using Rogowski coil technology.
Intuitive Interface and Instant Deployment: Plug & Play configuration integrated with the Ariadna platform enables fast, error-free setup, starting data recording immediately upon field installation.

Advanced Functionalities with IoT Analytics

Through integration with the Ariadna Smart IoT platform, data captured by LV DNA is processed using advanced algorithms and artificial intelligence, providing key functionalities such as:

Load balancing in transformers and lines
Power quality analysis, compliant with IEC 61000-4-30 and EN 50160 standards
Real-time visualization and alarms, with SCADA integration

Additionally, when cross-referenced with Smart Meter data:

Identification of network topology
Energy and loss balancing, distinguishing between technical and non-technical losses
Detection of electricity fraud, using AI models to identify irregular connections or meter tampering

Operational Impact and Strategic Benefits

The LV DNA solution not only enhances network analysis and diagnostics but also delivers tangible benefits across multiple areas:

Energy Efficiency

Reduces network losses and associated emissions, improves infrastructure planning, and supports the integration of new loads and distributed generation.

Safety

Prevents overloads, earth leakages, and risks from illegal connections. Enhances the safety of installations, technical staff, and the general public.

Cost Optimization

Reduces the number of field incidents and time per incident, while extending asset lifespan. Also enables more accurate billing by minimizing non-technical losses.

In summary, the LV DNA solution is a strategic answer for utilities aiming to modernize their low voltage networks quickly, efficiently, and accurately. Its portability, integration with IoT analytics tools, and advanced detection capabilities make it an essential tool for building smarter, safer, and more sustainable grids.
