Abstract

A method determines deviations between actual measured current values and setpoint current values in a number n (n≥2) of parallel-connected current-regulated circuit paths for the connection of a load with an energy source. A measurement of the total actual current value flowing from the energy source to the load is effected by a precision current measuring device with a low accuracy tolerance, and the measurement of partial currents in the circuit paths is effected by standard current measuring devices with a greater accuracy tolerance, in relation to the precision current measuring device. By an adjustment of the partial currents in the circuit paths, while maintaining a constant total current, values are obtained for a n-dimensional equation system corresponding to the number of circuit paths, the resolution of which, in the knowledge of the accurate total actual current, gives the deviations in the actual values of the partial currents.
