Abstract
There is described a method for measuring an alternating current which is generated using inverters and is fed into an AC power system, wherein a zero crossing signal of the AC power system is predefined, and wherein, triggered by the zero crossing signal, the measured alternating current is periodically adjusted in such a manner that an adjustment value which is assigned to the zero crossing signal is predefined, a measured value which is assigned to the zero crossing signal being adapted to said adjustment value. This method makes it possible for the measurement signal detected by a measuring circuit to be periodically adjusted using an adjustment value even during operation.
