Custom Current Transformers

At Stangenes Industries, we manufacture two types of current transformers: wide band current transformers and pulse current transformers. All of our current transformers can be constructed in a broad array of configurations and sizes, available directly in stock. Our wide band current transformers provide a maximum peak current range from 500 to 10,000 amps and a maximum RMS current range from 5 to 65 amps, based on model. Our pulse current transformers provide a maximum peak current range from 500 to 50,000 amps and a maximum RMS current range from 5 to 400 amps, also based on model.

Our current transformers offer complete isolation for the circuit to be measured, creating no ground currents. Possessing a electrostatic shielded construction, our top-notch transformers are equipped with an internal 50 ohm termination for coaxial cable matching and contain a variety of hole sizes to fit most conductors and voltages. In addition, both types of transformers offer a high, (+/-) 0.5 percent accuracy.

Offering a wide range of premium magnetic products, we invite you to contact Stangenes Industries today to learn more about our superior line of wide band and pulse current transformers.

General Information

Stangenes Current Transformers are available in many sizes and configurations directly from stock. Custom sizes and configurations can be designed to meet nearly any requirement.

For measurement of pulse and AC currents over a wide range of amplitudes, pulse lengths, and frequencies.

Stangenes Current Transformers have:

  • Complete isolation from the circuit to be measured (no ground currents)
  • Shielded construction
  • Internal 50 ohm termination for coaxial cable matching
  • High accuracy (±0.5%)
  • A variety of hole sizes to fit most conductors and voltages
Wide Band Current TransformersAccuracy: ±0.5% initial pulse response for all models. Specifications for transformer ratio, accuracy, and droop are at open circuit. Rise time and bandwidth are when terminated with 50 ohms. All models are electrostatically shielded and have a 50 ohm output impedance.
