Abstract
A method of sensing alternating current in a cable having at least a pair of longitudinal conductors each of the pair carrying a current equal or unequal in absolute value to the other in mutually opposite directions, is comprised of disposing a coil with its lateral plane adjacent the cable in a position whereby electromagnetic fields caused by the currents intersect primarily different portions of the coil and induce current in the coil, and detecting the induced current in the coil.
