Current Transformers

Current transformers are used to transform high currents to standardized values for control equipment as relays and meters.

The primary winding in a current transformer is incorporated in the line and carries the current flowing in the network. The magnitude of the secondary current is dependent of the ratio of the transformer.

Our offering

  • IMB

    IMB oil-minimum current transformers are based on a tank type (hairpin) design with over 60 years of ABB experience. It is the most sold current transformer worldwide.

  • TG

    Cores and secondary windings are located inside the head of the transformer. High voltage insulation is entirely obtained in SF6 gas instead of paper-oil.

  • MOCT

    The MOCT system satisfies current sensoring needs for revenue metering or protective relaying in a wide variety of applications.
