Abstract
A device () for the detection of current asymmetries in three-phase circuits (L, L, L) is provided. This device () has a first current measuring mechanism (S) for the measurement of first phase (L) and a second current measuring mechanism (S) for the measurement of a second phase (L). Furthermore, the device has a computing unit (ALU) which determines a current symmetry value (N; N) of the third phase (L) relative to the first phase (L) or second phase (L) from the measured first phase and from the measured second phase. Moreover, an associated method is also provided.
