Abstract
Compact round rotational single sheet testers (RRSSTs) can achieve very high flux densities ( $\sim\!2 \text{T}$ at 60 Hz), owing to sinusoidal distribution of the magnetizing magnetomotive force (MMF), equalization of reluctance, a reduction in their diametrical size and longer stack lengths (deep yokes). The last two measures result in an increase in the magnetic field $z$ -component $(H_{z})$ , which is often reduced by shielding. This paper shows that a given shield distance is not effective in minimizing $H_{z}$ over the entire flux density range. The impact of the magnetizer diametrical size and the yoke depth on $H_{z}$ is also compared with shielding. Finally, this paper shows that magnetic properties contribute significantly to $H_{z}$ at very high flux densities, whereas the magnetic interaction of the sample and shields, reduce the effectiveness of shielding in deep saturation at 2 T.
