摘要： The invention relates to a measuring arrangement (12) 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 (1) for measuring current in accordance with four conductor technology and a physically integrated measuring circuit (17) for measuring the voltage which is dropped across the current sense resistor (1). The invention provides several pairs of voltage taps for measuring the electrical voltage which is dropped across the resistor element (4), wherein the pairs of voltage taps are connected to the measuring circuit (17). The invention further provides two busbar connections (13, 14) for connection to two busbars (15, 16). 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.

The current (I) perpendicularly enters or leaves the connections parts (2, 3) via their outer surfaces. In addition, the voltage taps are attached to the inner side of the U-shaped resistor (1), and contact the connection parts (2, 3) close to the transition to the resistor element (4).

摘要： The invention relates to a measuring resistor (1), in particular a low-resistance current-measuring resistor, comprising two terminal parts (2, 3) that consist of a conductor material for introducing and discharging a current, and a resistor element (4) that consists of a resistor material, wherein the resistor element (4) is arranged between the two terminal parts (2, 3) in the direction of the current and current flows through the resistor element (4). According to one variant of the invention, the measuring resistor (1) has several pairs of voltage-measuring contacts (7) for measuring the voltage falling across the resistor element (4) in order to be able to compensate metrologically for inhomogeneities in the current density. In contrast, according to another variant of the invention, one pair of voltage-measuring contacts (7) is arranged at a location at which the measuring resistor (1) exhibits neither a capacitive behavior nor an inductive behavior, such that the current flowing through the measuring resistor (1) and the voltage across the voltage-measuring contacts (7) are substantially in phase.

摘要： The invention concerns a current measuring device for measuring an electric current (Ip, In) according to the four-wire technology with a low resistance current measuring resistor (RCu1, RCu, R0). The invention also provides for a compensating resistor (Rp) consisting of a fixed resistor connected in parallel with the resistor element (R0) of the low-resistance current measuring resistor (RCu1, RCu, R0) in order to at least partially compensate for the temperature dependence of the resistance value, so that the current measuring device has two current paths, namely a main current path through the resistor element (R0) on the one hand and a secondary current path through the compensating resistor (Rp) on the other hand.
