Description

The WITT Bridge is the measurement platform for direct current and traction power systems: it features a multi-layered, modular design, underpinned by high safety standards. This is precisely what makes it the foundation for Traction Power 4.0 – because it is this combination of modularity and safety that enables bespoke solutions, even where particularly stringent safety requirements apply.

Traction Power 4.0 – the right solution for every system

Whether it’s a light rail system, an underground railway, a charging station or a battery buffer, whether it’s a new build or a retrofit: no two regional rail traction power systems are alike, and each has its own specific requirements for insulation and cable monitoring. At the same time, the same strict specifications apply to all of them – from standards such as EN 50122 to operator-specific guidelines. Rather than developing a separate solution for every application, WB components are based on a modular design principle: standardised basic functions that can be expanded to include additional measurement channels and sensors. The result is bespoke protection that is just as easy to operate as a standard solution – the foundation for Traction Power 4.0 in your system.

WITT Bridge measurement technology: reliably analogue, digitally connected

At the heart of every WITT Bridge component is the combination of a genuine analogue measurement stage and high-quality digitalisation – providing reliable protection, even at high voltages. Standardised functions, consistent modularity and end-to-end measurement data acquisition make WITT Bridge components the building blocks of your bespoke Traction Power 4.0 system.

Thanks to flexible processes and intelligent measurement, control and regulation systems, we adapt to your specific requirements. All critical thresholds are monitored in real time, and the relevant measurement data is available to you at all times for your own analyses. The result: a transparent basis for decision-making that ensures greater safety and operational efficiency – Traction Power 4.0 in practice.

Manufacturing takes place in Brandenburg – either as one-off items or in small batches – and the products are used worldwide. WB components are specially designed for demanding railway environments and perform key functions: measurement, regulation, control and data transmission.

Made in Germany: Manufacturing and quality assurance under one roof

WITT-Bridge components are manufactured entirely in our own production facility in Brandenburg – from component manufacturing and electromechanical assembly right through to commissioning under realistic operating conditions. Because our systems monitor installations where a failure in an emergency could compromise passenger safety, quality assurance is not merely a downstream testing step for us, but is integrated into every stage of production: An automated test system with 128 channels, reference measurement cards from National Instruments and our own signal generators reliably test even complex scenarios – all embedded within our processes. For you, this means documented, traceable quality that goes far beyond the minimum legal requirements, and devices that can be integrated directly and seamlessly into your existing system.
