Abstract
The invention relates to a measuring arrangement () for measuring an electric current (I) in the high-current range, in particular in the current range of more than 1 kA, having a low-resistance current sense resistor () for measuring current in accordance with four conductor technology and a physically integrated measuring circuit () for measuring the voltage which is dropped across the current sense resistor (). The invention provides several pairs of voltage taps for measuring the electrical voltage which is dropped across the resistor element (), wherein the pairs of voltage taps are connected to the measuring circuit (). The invention further provides two busbar connections () for connection to two busbars (). Corrections of the temperature coefficient, the thermoelectric voltage and the offset and also a high sampling rate and resolution allow high-resolution measurement of a DC current in a high AC current.
