Abstract:
A method for measuring a current level of an alternating current uses a current transformer having a measurement winding and a test winding. The resistance of the test winding is measured, the temperature of the test winding and therefore of the measurement winding is determined therefrom, and a value for a current level measured on the measurement winding is corrected using that temperature.
