Current Sense Transformers

Current Sense Transformers are designed to detect and measure current flow in an isolated conductor or a primary winding and produce a proportional alternating current in a secondary winding. The frequency range is 2 Hz to 1 MHz with a current rating of 125 mA to 4000 A. The three types are Invasive, Non-Invasive (Solid Core), and Non-Invasive (Split Core).
