Abstract :
The authors developed an AC standard shunt (rated 10 A, 0.1 /spl Omega/), for frequencies from DC to 10 kHz, which has a highly stable resistance value and small phase angle error. By using this AC standard shunt, AC power and current may be measured with high accuracy. The stability and uncertainty of the shunt correspond to 3 ppm with regard to AC power measurement at 1 kHz.
