Solid core transformer

Core balance transformer ΔIC & ΔIP

Available from Ø 15 to Ø 300 mm

Available from diameter 15 to diameter 300 mm

TCT designs, manufactures and sells measuring core balance transformers, as per your needs, and for the strictest applications. The balance core transformers are used in low voltage, mainly by manufacturers of monitoring stations and by electrical panel installers. These transformers are adapted to all kind of primary passages (bars or cables).

The range of our core balance transformers is available with FeNi or Nanocrystalline magnetic cores, available in diameters from 15 to 300mm with a transformation ratio of 600/1 and 1000/1 for a primary current until 600A. The range is also available with a ratio of 8000/1 on certain models.

TCT offers a range of customizable core balance transformers, on request. Thereby, the connecting system, the fastening system, the sealable protection cover, the centering system and the transformation ratio can be adapted to your needs.
