Low Power Transducers

Main applications

  • The low power current and voltage transducers can be used for a wide range of medium and high voltage applications where they replace the conventional measuring transformers for measurement and protection purposes.
  • The Voltage Transducers are based on resistive as well as resistive-capacitive dividers.
  • The Current Transducers are based on an iron core or an air core design and provide a secondary voltage which represents the primary current.
  • Connection capability for multiple protection and measuring devices.
  • Current Transducers provide a linear transmission up to short-circuit
    current.
  • Completely EMC shielded: Immune to RFI/EMI
