Abstract
In order to determine amplitudes of measurement signals originating from an AC power supply and to determine the phase shift (ø) between measurement signals more simply, the measurement signals are processed in measurement signal operation devices to form auxiliary signals each having a constant AC amplitude and to obtain first measurement values (v, a, rssi, rssi, rssi), in particular, from amplification factors (v) that are applied to the measurement signal (m, m, m). The phase shift between two auxiliary signals (h, h', h′, h′) is further determined as a second measurement value, in particular, by means of the time difference (Δt) between the zero passages of the auxiliary signals (h, h′, h′, h′).
