Power Measurement
In times of power electronics Power Measurement (PM) is not only a multiplication of current and voltage but primarily an analysis of interfering high-frequency and broadband signals. Sinusoidal qualities, as once electric current and voltage, are displaced by pulse packages; power ratings do not have only 50 or 60 Hz any longer.
Beside the calculation of power for the fundamental oscillation and all signals, questions of harmonics, symmetries, flickers and start-up processes arise. Switching frequencies of drive mechanisms having several kHz require sampling rates of several hundred kHz and analogical bandwidths of input amplifiers. The demand of preciseness is far below 0.1 % and this should preferably be the case in the entire frequency spectrum and amplification range.
