Function

Current measurement transformer intended to convert a primary AC current up to 300 A into a standard 5 A secondary signal for connection to measuring and monitoring equipment.

Primary functions:

  • measurement of AC current in power distribution circuits

  • electrical isolation between primary conductor and secondary measurement circuit

  • retrofit installation on existing conductors without circuit interruption

Typical applications:

  • energy meters with 5 A current inputs

  • power monitoring and sub-metering systems

  • electrical distribution boards in commercial and industrial installations
