Custom Design Toroidal Current-Sensing Transformers

Our toroidal current-sensing transformers measure current flowing in power lines and busbars. Also called instrument transformers, they can be furnished with protective insulation by means of taping, resin dipping or epoxy potting. They can also be cast in epoxy and encapsulated neither alone or grouped together for multi-phase applications. We offer an expanding line of standard design current transformers as a cost-effective solution for many applications. Additionally, we design current sensing transformers to customers' own specifications.

Voltage Generating Types
Electronic power monitoring equipment sometimes relies on a current transformer to produce a voltage signal. This is accomplished with a relatively high turns ratio (typically 1000 to 2000) with a load resistor mounted across the winding. This type of current transformer is often mounted directly onto a PC board. Besides flying leads, we can supply the transformer mounted vertically or horizontally in a carrier with pins for PC mount.

Please see standard design current sensing transformers for reference. Please call us to discuss your application, or simply
