Current comparator for both AC and DC ratio measurements with 10-8-level accuracy
Hidekazu Muramatsu, Yuta Kainuma, Hiromitsu Kato +11
Accurate measurements of alternating current (AC) and direct current(DC) ratios are fundamental to electric power metrology. However, conventional current comparators for AC and DC…
