Current transformer

Current transformer

Our active standard current transformers based on the current comparator principle. With an indicator winding the magnetic flux in the iron core is measured and fed back into the iron core to make the magnetic flux zero. This way we can grant a 10 ppm uncertainty for ratio and phase and this over a very broad working range.     The application of our standard current transformers include range extension for capacitance and tand measurements (cable drums or power capacitors), as reference for current transformer measurements as well as calibration and metrology purposes.
