Abstract :
A power standard for calibrating high-accuracy wattmeters and watt-hour meters at 50/60 Hz is described. The technique is a modification of a previously described approach that utilizes a power bridge based on a current comparator. This standard was used in a recent international comparison of 50/60 Hz power.
