Abstract

A phase angle/ power factor meter with matching output for computer interface is proposed. Usually, a set of instruments composed by a voltmeter, an ammeter and a wattmeter, is used as the power factor (PF) standard system. The PF is then calculated from that value being, in a derived magnitude. Using the proposed phase angle meter, the phase angle can be read directly based on the measurement of the time signals between current and voltage zero crossing. The voltage and current are sampled from the main supply. The number of pulse between the current and voltage zero crossing, will go through a 3-digit up counter. The 7-segment digital read-out will display the phase angle.
