Abstract
A device for the measurement of audio-frequency power, voltage and current is discussed. The full range of power factors are accommodated (cos φ=0 to 1). Voltage and current measuring ranges are 15-600 V and 0.1-10 A, respectively. When cos φ=1, the permissible error of the power measurement is from 50 to 150 p.p.m. over the frequency range of 40 Hz to 10 kHz (including the line power frequency)
