  • Power meter with two detector elements for a power measurement even of extremely low frequencies
    Patent number: 9939473
    Abstract: The invention relates to a power meter with a two-path or multipath detector comprising at least two detector elements. Each detector element generates an output voltage. In order to detect an electrical power of an alternating electrical input signal, the sum and the difference of the output voltages of the detector elements are formed separately from one another.
