IPC: G01R22/00
Filed: 1981-03-14
Abstract: PURPOSE:To make it possible to measure the reactive power highly accurately by providing a frequency detector using a crystal oscillator and a frequency to voltage converter. CONSTITUTION:A detected voltage ev corresponding to a negative voltage through a transformer 11 and a phase shifter 13 is multiplied by a detected voltage corresponding to a consumption current having the same phase as that of the ev from a current transformer 12, in a multiplier circuit 14, and the power is computed. Meanwhile, the detected voltage from the transformer 11 is applied to a D type filp flop through a comparator 21 whose reference is a zero voltage of the frequency converter 15. Said FF22 is cleared by a clearing signal outputted from a counter 24 when a clock from the crystal oscillator 23 is counted up to a specified number, and generates a Q output having a specified width at a specified level proportional to frequency of the voltage ev. Then a voltage which is accurately proportional to the frequency ?of the voltage ev is generated from the frequency to voltage converter 16 formed by an integrator 25. Said voltage and the voltage corresponding to the power operated by the circuit 14 are processed in a multiplier 17 and an integrator 18 and a voltage which does not include the frequency component corresponding to the reactive power is taken out. Thus the reactive power is measured highly accurately.
