Measuring device for use in control device utilized for transmission of power from photovoltaic system into energy supply network, has evaluation unit determining whether inductor is located in saturated state based on measurement signal

The device has an acoustic sensor (18) arranged in vicinity of an inductor to be monitored for detecting an acoustic signal transmitted by the inductor. A band-pass filter (22) filters out a frequency range in which the inductor is strongly emitted in a saturation state. An evaluation unit (24) dete...
