Show affiliationsThe development of an electronic power factor meter to replace conventional electrodynamic types is described. The design is based on an analogue-to-digital converter (ADC) provided with ratiometric facilities. A signal proportional to the peak voltage (Vm) is applied to the reference input voltage of the ADC, while another signal proportional to the product of the peak voltage (Vm) and power factor (cos phi ) is applied to the analogue input. The result is a power factor reading.
