Now there's an economical, proven way to gain visibility to distribution grid electrical measurements
How can you gain insights into the status of underground environments? What’s the best way to maintain and extend the life of existing infrastructure? How do you replace assets as needed in a cost-effective manner? Can you get the best of both worlds: enhancing current infrastructure while preparing for future, data-driven capabilities?
How do you “feed” increasingly data-hungry consumers (especially Millennials)? How do you prepare for new services like home energy management, pre-paid billing, and real-time energy usage information? Key Insight: The days of the passive energy consumer are rapidly coming to an end.
How you integrate Distributed Energy Resources (DERs)? What are the system implications of the Era of “Prosumer”? - According to a 2017 report from the IEA (PDF, 3.45 MB): “… Record performance in 2016 forms the bedrock of the IEA’s electricity forecast, which sees continued strong growth through 2022, with renewable electricity capacity forecast to expand by over 920 GW, an increase of 43%. This year’s renewable forecast is 12% higher than last year, thanks mostly to solar PV upward revisions in China and India.
What does the future of urban areas look like? In the words of an Energy.gov report: “As smart cities become more prolific – they are already appearing in a number of cities from South Korea to Spain to the US – the grid will be increasingly relied upon to handle multidirectional communications between many different entities and to balance the innovations that already have, and will continue, to develop. The grid’s integral role in the success of… smart cities is already helping to drive research and development of the advanced grid, and will continue to do so.”
Outages here have widespread impacts. With distributed intelligence, i.e. high-accuracy sensing in MV environments, you gain critical insights.
The ideal business case for Grid Modernization is one that combines extending the life of current assets in a cost-effective manner… while preparing for future grid opportunities.

Electrical Network Design and Construction,
Enel Distribuzione and 3M partnered in 2013 to collaborate on the development of the Smart Grid. The medium voltage (MV) grid intelligence at that time was concentrated on just a few nodes.
To create the foundation for broadly distributed intelligence in the MV grid.
The 3M solution consisted of a pre-calibrated, highly accurate, passive current and voltage sensors, embedded into an indoor termination. The sensored termination was suitable for retrofitting a large variety of existing MV switchgear without the need to
upgrade structures. A modular system was utilized to enable application extension to plug-in interfaces.
Reduced Operation & Maintenance (O&M) costs and reduced penalties due to service interruption. Estimated yearly savings above $200 M in full deployment. More than 30,000 units installed in Italy. Pilots begun in Romania, Colombia, and Brazil.
The 3M™ Sensored Cable Accessory QX-Generation 2.0 enables you to measure critical parameters (voltage, current, phase angle) in an underground MV electrical network. This solution incorporates highly accurate Voltage and Current measurement integrated into a medium voltage accessory: which means you get precise measurements without modification of the installed equipment. Additionally, the sensors are passive components thereby not requiring an external power source for sensing.
3M patented connection system and cold shrink technology assure the easy and fast installation for a wide range of cable cross sections.
