摘要：
A portable instrument for measuring large direct currents based on a Rogowski loop, is described. All functional operations are carried out by digital equipment. Results of an analysis are given which show that such instruments can be constructed with an accuracy class of 0.05 and higher. This enables them to be used as standard measuring instruments for calibrating fixed systems without the need to dismantle them.
