Selecting Current Sensors and Transformers· PDF filehighest flux density that will be seen by the sensor or transformer. Exceeding 2000 Gauss for most AC current sensors means that the output becomes non-linear vs. the current being sensed and the output voltage is no longer strictly proportional to the input current. Higher secondary turns helps keep the flux density below this limit.
