Moisture levels in dry air, SF6 or alternative gas assets can lead to potential catastrophic failure and reduced asset life. EMT Moisture Pro is a fast, portable, accurate, smart dew meter for moisture determination in critical assets.

Adoption of SF6 alternative gases increases the maintenance and analysis burden on utility staff, requiring multiple analysers to fulfil test and analysis procedures. This requires increased levels of capital budget; increased time to undertake maintenance tasks; resulting in greater inefficiencies onsite. The EMT Zerowaste Rapide Eco+ solves this problem by fulfilling all measurement requirements in one, simple, portable device. Built on the existing market leading EMT Rapide+ platform, Eco+ is the world’s first 4in1 analyser for the measurement of SF6, Novec 4710, Novec 5110 and Dry Air insulating gas applications.

AFS corona generators are THE standard for foil extrusion and the packaging industry. It is not without reason that the largest machine manufacturers opt for AFS as their standard equipment. The initial investment cost of any system is only part of the total running costs over the life time of a machine. Reliability and high efficiency results in minimum downtime and loss of production. The failure of a corona treater system can result in a total plant shutdown costing far more than the difference in price between a low quality and higher quality treatment system.

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

Substations are transformer or distribution centers made of sheet steel in desired dimensions. They are suitable for use of all types of MV switchgears and LV panels. They are manufactured in the requirement number of sections and doors according to the project design. Strong construction made of sheet steel and profiles is painted with electrostatic powder paint or liquid paint for high corrosion resistance. In order to prevent the strong solar radiation in hot summer, the shell can be equipped with heat insulation material with low thermal conductivity, the most used fillers are: rock wool board, polystyrene foam, etc. Modular design in requested depth, width and length, in average 4 times lighter than a concrete version along with easy transport and commissioning are just some of the advantages of this solution. Compact substations are suitable for residential quarters, urban public utilities, renewable power plants, power distribution etc

VOLTAGE design and build power transformer stations of industrial scale

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.

Multiple EM 600 stations in combination with a cost-effective transfer system provide the additional benefits of the EM 700 series: higher degree of automation, no limit to the number of stations, modular and scalable, single- or double-sided processing

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

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.
