Abstract :
The primary standard of the loss angle unit containing special capacitors and a transformer bridge, has been developed at VNIIM. Different methods for reproduction of the unit are used, the measurement results agree within 0.1 /spl mu/rad at the frequency 1 kHz. The measurement uncertainty is /spl plusmn/0.2 /spl mu/rad, k=2.
