Current Transformers

VAC Magnetics' current transformers (CT) for electronic electricity meters, current monitoring, and protection applications

Image of VAC Magnetics' Current TransformersVAC Magnetics' CTs allow innovative and cost-effective solutions based on nanocrystalline materials from the VITROPERM® alloy family and have been proven to provide a robust and accurate solution in a wide range of meter designs. They offer technical advantages, such as a high level of linearity, low temperature dependence, and a compact design.

The share of energy from renewable sources has tremendously increased in recent years. This evolution leads to a complex electricity grid architecture, which must ensure safe electricity transmission and distribution, and a sufficient supply for all application areas. To guarantee a resource- and energy-efficient operation of the grid, so-called network management systems become necessary. CTs that enable continuous monitoring of the electricity usage are needed. VAC's CTs that combine modern materials and innovative engineering, provide a solution for fulfilling network monitoring demands. VAC offers various current detection options for monitoring, control, and protection.
