Witt Solutions GmbH – Your Specialist for Monitoring Systems in Railway

We offer customized measurement, monitoring and test technology for DC applications of railway infrastructure, which really fit your needs.

All of our Professional Power monitoring products (PPM) are based on decades of experience and are complemented by new, modern intelligent 4.0 technologies. We manufacture in our own factory in Germany. It goes without saying, that all of products in the field of personal, building and railway infrastructure protection meet the requirements of DIN EN 50122, 50123 50124, 50526 and the high standards of the German Federal Railway Authority.

What We Offer

Earth Potential Monitoring

When operating direct current (DC) railways with return lines through the rails, the different earthing resistors give rise to voltages that can be dangerous for people and buildings. These measuring instruments monitor the potentials of the connected earths and evaluate the voltages produced. The device is designed to be mounted on a top-hat rail and requires no auxiliary voltage. The power supply is provided by the input voltage to be monitored.

Short-Circuit System & VLD

We are proud to say that we have the biggest portfolio of self-resetting short-circuit devices and Voltage liming devices (VLD) in the German market. We are able to determined earth potentials at any point. The standardized systems from WITT Solutions GmbH can be individually adapted. This high flexibility is ensured by a modular and safe measuring system.

Also our systems have been approved by the German Federal Railway Authority and meet the high requirements of DB Netz AG for the safety of German railway infrastructure.

Cable Monitoring (e.g. Insulation Monitoring, Theft Protection)

The monitoring of a cable is a special task, because in addition to the actual use of the cable, additional information must be determined in order to check the functionality of the cable.

WITT Solutions GmbH provides different monitoring systems for the respective railway task:

  • Insulation monitoring
  • Position detection of the fault or interference
  • Cable temperature monitoring

Traction Voltage Monitoring (TVM)

These devices are used to monitor DC voltage values. Typical application is the distance-dependent monitoring of overhead line voltage in a DC railway system. This becomes necessary, for example, if the voltage should fall below a certain value or lie within a certain threshold value before the individual line sections.

Stray Current Monitoring (SCM)

Stray current is that part of the return current that does not return through the return line but through the ground or through a tunnel or structure to the substation. Corrosion occurs on metallic materials. In general, insulation is therefore formed between the return conductor and the earth. Due to aging and environmental influences, the insulation can become defective, resulting in stray current effects.

If you have a DC related problem in the field of railway, we have the Solution! For more information, visit our website or give us a call!
