A wattmeter based on phase measurements with few µW/VA uncertainty

Slomovitz, Daniel - Faverio, Carlos - Trigo, Leonardo - Izquierdo, Daniel

Resumen:

The proposed wattmeter is based on separate measurements of voltage, current and power factor. This last parameter is calculated from the phase angle between voltage and current. To achieve uncertainties around 1 part in 10⁶, many error sources have been analyzed. New methods are used for scaling (120 V to 1 V and 10 A to 10 mA), and for reducing the effect of waveform distortion.
