Abstract
The present invention relates to a grid monitoring system, in particular a grid monitoring system enabling real-time monitoring of grid variables, e.g. voltage and current, in electrical power systems, such as single or three-phase networks. The grid monitoring system includes a harmonic detection unit being adapted to subtract harmonics of an input signal before feeding the input signal to a plurality of signal generators in the harmonic detection unit.
