Abstract :
The paper describes a transportable ac power and energy standard developed at VNIIM. Based on a thermal principle, the instrument performs ac-dc transfer and absolute power and energy measurements in the frequency range from 40 to 500 Hz. The ac-dc transfer accuracy is better than 10 ppm at unity power factor and better than 30 ppm at 0.5 power factor.<>
