Ring type CTs for busbars


These CTs are specially designed on a case-by-case basis for each specifications document. Several parameters, including the size of the enclosure, the size and type of the conductor, the insulation voltage and the primary current have to be considered to define the most suitable product.

Some can be insulated for low voltages, others require a screen to be connected to the primary conductor and others require a compensation winding to avoid any influence between phases closed to the neutral point.

Each request undergoes a special study based on your specifications.

Sadtem now has a large reference list for these kinds of transformers, in thermal power stations as well as hydraulic projects and nuclear power plants. Feel free to contact us to find out which product offering is best suited to your request.

Here are some examples of plans and completed projects:
