Current transformer is designed to create a secondary current that is proportional to the primary current. Current transformers are defined according to their conversion ratios, accuracy classes and power ratings. Accuracy class varies depending on the ares of use for the transformer. Classes are divided into oiled and dry types.

Maintenance, testing and installation of these transformers are performed by our company with the assistance of quallified personnel.
