Witt Solutions GmbH – Your Specialist for Measuring and Testing Systems
Within the scope of Professional Power Monitoring (PPM), we manufacture and sell measurement and test technology for medium voltage up to 50 kV AC/DC and currents up to 50 kA for the power supply of railway infrastructure as well as industrial applications. Our products are based on decades of experience and are complemented by new, modern intelligent 4.0 technologies. In order to guarantee our high-quality standards, we manufacture in our own factory in Germany with a high degree of verticality. In the field of personal and building protection, we offer products that meet the requirements of DIN EN 50122, 50123 50124, 50526 and the high standards of the German Federal Railway Authority.
What We Offer:
- Monitoring of energy potentials and equipotential bonding by means of ground short circuits to avoid contact voltages:
When operating direct current 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.
- Monitoring of energy potentials and equalization of potentials by voltage limiting devices (VLDs) to prevent corrosion:
We are proud to have been approved by the German Federal Railway Authority for EscS 701 (SBE voltage limiter) since 2003 and for EscS 7 (EKS1000 earthing short-circuiter) since 2016, thus meeting the high requirements of DB Netz AG. True innovation is when proven things are reinvented. With the new generation of products, we not only meet the latest standards, but also systematically follow the path of modularization and digitization. Thanks to modern interfaces, we provide a wide range of measurement data and status information or can receive parameters on request.
- Determination of earth potentials at any point.
- Wiring monitoring (e.g. insulation monitoring, theft, etc.):
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. We offer several measuring devices for this purpose. Starting with a simple check of the cable insulation up to fault location. An accuracy of up to 5 % can be achieved here.
- Monitoring of the traction voltage:
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.
- Centralized data collection as a basis for e.g. stray current monitoring
Excerpt from Industrial Applications:
- At Siemens, no medium and high-voltage switch leaves the factory without our measuring systems being involved in the tests.
- In the laboratory of BSH GmbH, dishwashers and washing machines with measuring devices were developed.
Our Quality, Your Potential.
We are aware of our responsibility as a supplier of measuring and test systems. We know that our systems only meet the requirements of our customers if we ourselves can guarantee a high level of quality. We realise this in the form of modern manufacturing, testing and inspection procedures, such as quality portals and automated test procedures.
