Measurement data acquisition from medium-voltage switches

Man-in-the-Middle-Solution for medium-voltage switchgear for Siemens

For several years now, WITT Solutions has been developing and supplying a bespoke measurement data acquisition system operating as a ‘man-in-the-middle’ system for Siemens – at both its Berlin and Mexico sites. This innovative solution is used to process and digitise sensor signals from medium-voltage switches.

How it works: The measurement box acts as a smart interface: it captures analogue signals from the switches’ sensors, processes them and converts them into digital formats. This enables precise monitoring and control – essential for modern energy infrastructure.

Technical highlights:

  • Flexible signal processing: Adaptation to different sensor types and signal types
  • Modular hardware: use of Intentional Instrument cards and custom-designed adapter cards for maximum compatibility and scalability
  • Reliable data transmission: real-time digitisation for efficient integration into control and monitoring systems

The benefit for you: With our solution, you benefit from seamless integration into existing Siemens systems – designed to meet the highest standards of precision and reliability.

For those interested in the technical side:

Applications: Medium-voltage switches in power distribution networks and industrial plants

Signal types: Support for analogue and digital sensor signals

Hardware: A combination of standard and proprietary adapter cards for maximum flexibility


Why WITT Solutions? Experience, precision and partnership: Siemens has relied on our expertise in bespoke measurement and control solutions for many years.
