Current Transformers

High Precision Current Measurement

Current Transformers for 50 Hz/60 Hz energy meters require core materials with highest permeability and linearity.

Benefits:

  • Low phase & amplitude error over wide temperature range
  • Wide current range (6 A up to 200 A)
  • Shielded versions
  • Very compact DC-tolerant versions for IEC meters
  • ANSI types from 20 A to 320 A
  • Phase-amplitude-error characteristics available
  • ANSI meters
  • IEC meters
  • Monitoring & protection

General Characteristics

  • Alternative types for PCB mounting or wire connection
  • Innovative packaging offering high flexibility for customized versions
  • Low phase & amplitude error over wide temperature range
  • Wide current range (6 A up to 200 A)
  • Shielded versions
  • Very compact DC-tolerant versions for IEC meters
  • ANSI types from 20 A to 320 A
  • Phase-amplitude-error characteristics available
  • High linearity for easy meter calibration

Smart electronic electricity meters are being installed in households and the industry worldwide. We supply leading smart meter manufacturers in the IEC and ANSI markets with VAC current transformers and support our customers very successfully for more than 20 years.

Innovative and cost-effective solutions based on nanocrystalline materials from the VITROPERM® alloy family have been proven to provide a robust and accurate solution in a wide range of meter designs. Our current transformers offer many technical advantages, such as a high level of linearity, low temperature dependence and a compact design.

High accuracy, consistent high quality and innovative designs set new standards worldwide for precision current measurement. In addition to our standard current transformers for operation up to 400 A we also offer modular solutions, such as three CTs in one housing for simplified assembly in poly-phase meters or versions with built-in shielding for protection against external magnetic fields. With advanced design software we simulate phase and amplitude errors reliably, so our customer can achieve the optimum meter performance with our standard or customized solutions.
