Title :
A novel method of current scaling for AC watt and watthour
Author :
Edwards, Shannon
Abstract :
A novel method for precision scaling of currents for use in AC watt and watthour measurements. The technique pays particular attention to keeping the effect of the magnitude and phase errors of the scaling well below 1 μW/VA or 1 μWh/VAh in the watt and watthour measurements.
