Low Voltage Distribution Network Analyzer

The need for operators to manage their networks more efficiently by means of an effective digitalisation of the system, as a complementary method to traditional network reinforcement, makes it necessary to provide alternative monitoring solutions to fixed monitoring, because it is not always possible or profitable to install it.

At Merytronic, together with Ariadna, we have developed a portable solution for monitoring LV networks, consisting of LV DNA device, a portable data logger, together with the analytics provided by Ariadna Smart IoT platform.

This solution offers several advantages, such as robustness, ease of use and cost-effectiveness compared to fixed installations of monitoring systems, but it also offers a very important advantage: portability. It allows the focus of analytics to be placed on the points where it is considered necessary to have more information on the behaviour of the network.

Main functionalities of the Low Voltage portable monitoring system

• Portable network analyser
• Electrical Losses
• Measurement of Transformer and Feeder Load
• Solving Supply Quality Problems

Fraud detection solution

One of the main objectives of a modern, digitalized network is the efficient detection and reduction of non-technical losses. Based on the data recorded by the LV-DNA device, Ariadna Smart IoT platform allows to make energy balance calculations at various network levels from a single environment:

• Transformer and feeder balance
• Energy balance at feeder level
• Power Loss analysis: kWh per Transformer and feeder
• Shunt tampered meter detection

This solution contributes to enhancing DSO by increasing grid efficiency, minimizing energy wastage, and reducing CO2 emissions. It also works to decrease the overall costs of the system and enhance safety.
