Sensors for the Medium voltage grid
Now there's an economical, proven way to gain visibility to distribution grid electrical measurements.
Attend our two webinars to learn how our Sensored Cable Accessories can help and automate the medium voltage grid:
The first webinar “Digitising the Medium Voltage Underground Grid” will provide an introduction and the second one “Enabling ENEL’s Smart Grid Development is about the experience of ENEL Power Utility.
3M™ Sensored Cable Accessories (SCA)
3M™ Sensored Cable Accessories (SCA) provide a retrofittable, compact and economical way for Distribution System Operators (DSOs) to gain visibility and data from their distribution grid with voltage and current measurements.
As the need and importance of measurement and data in the underground grid rises, 3M SCA provides a simple path to high accuracy solutions for assessing and improving fault detection, power flow and power quality. The advent of new regulations and integration of renewables into the medium voltage network, make the need for high accuracy measurements critical for assessing the health of your electrical grid and better managing the future of the network’s grid modernisation.

3M helps provide visibility into the medium voltage (MV) electrical infrastructure
3M Sensored accessories easily retrofit inside cable compartments, air insulated switches, gas insulated switches or on transformers inside substations. When you upgrade your existing medium voltage substation with our product, you gain high accurate sensing and overall insight into multiple nodes without the need to replace.
3M Sensored Cable Accessories: Sensing Things to Come
Right for now, right for tomorrow and no additional space needed within your grid.
Voltage and Current Measurement Made Easy
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 one product 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 Sensor System and cold shrink technology assure the easy and fast installation for a wide range of cable cross sections.
