High-voltage dividers - Import export

The CSN® type RCVoltage Dividers consist of a proven reliable and high accuracy resistivecapacitive voltage divider. These are used for voltage measurement for control and protection systems in HVDC links and research institutes. The base for our Voltage Dividers are metal wire resistor webs that have been embedded in epoxy resin under vacuum. In this way, optimal protection against external influences can be achieved. Depending on the installation requirements (outdoor or indoor application), special designs of the voltage dividers adapted on the site requirements are used. The insulation medium (air, N2, SF6) can be easily adapted to the special requirements of the application. Our CSN® RCVoltage Dividers are characterized by

The CSN® HECT, HEVT and HECT/VT by Schniewindt combines proven sensor technology and opticaldigital data transfer according to the standard IEC 6185092, creating a future orientated solution for applications in high voltage AC substations. The required values to be measured are recorded in analog signal form by conventional sensor elements (R/C high voltage divider for voltage measurement and Rogowski coil for current measurement) on HVline potential and transferred to the RemoteDataModule (RDM) mounted in the head construction of the instrument transformer. The RDM converts the recorded data into a digital serial protocol and transmits them via optical fiber to the Merging Unit (MU), located in the control room. The distance between instrument transformer and MU can be up to 1 km. The MU transfers the data protocol of three instrument transformers into the protocol according to IEC 6185092. For signal output

We provide and implement solutions for high-voltage underground and overhead lines. Therefore, we offer supervision and/or installation for cables, conductors and related accessories, granting for the entire system. All the works are performed by highly qualified and certified workforce.

The Metzner EM 300 platform offers further convenience in high-voltage cable processing through a quick change of process tools and faster cycle times. Depending on the requirements, the HV cable processing machine can thus be equipped with different tools for cable processing. This means that the EM 300 can be used for several processing steps and is prepared for a wide range of processes. In addition, with the EM 300 we protect your investment by offering improved expandability that enables “plug-and-play” integration of future new applications.

Metzner has a clear understanding of the future and transforms existing processes into fully automated system solutions. Workstations that were previously operated separately are now combined into fully automatic production lines. The starting point of an automatic processing line is the cable that is wound on a reel. The end result is a finished cable with a completely assembled plug system
