Abstract

The present invention relates to an AC current detector, having an iron core, current input coil, high-stability and low-temperature coefficient current output coil and reading coil, in serial connection with the testing current circuit through a current input coil, while the current induced on the secondary end of the iron core flows completely through the current output coil before the induced voltage on the coil is measured with a testing instrument, making such an arrangement lower the power loss while eliminating errors in the measurement of current caused by temperature surge, resistance temperature coefficient and impedance load effect, for measurement of AC current of maximum precision.
