Shields, John Q.
Abstract :
An absolute measurement of loss angle has recently been completed at NBS. The measurement utilized a special toroidal cross capacitor in which the effects of dielectric films are greatly attenuated. The resulting unit of loss angle has an estimated uncertainty of 0.02 ¿rad at an optimum frequency of 1592 Hz.
