Abstract
A measuring arrangement for redundantly determining a quantitative value of a current flow includes a first and second current-measuring modules connected in parallel, where the first current-measuring module includes a first analogue input and a first current measurement resistor and a voltage-measuring unit to determine the value of current flowing into the analogue input and through the first current measurement resistor, the second current measuring module includes a second analogue input and a second current measurement resistor and a voltage-measuring unit to determine the value of current flowing into the second analogue input and through the second current measurement resistor, and includes a control unit that detects a gradual change in voltages determined by the voltage-measuring units, and when gradual changes in the voltages that are counter to each other occur, a current-measuring module is excluded from the determination of the quantitative value of the current flow.
