Abstract

Short circuit detection is performed on a plate structure (10) in which a group of first electrical conductors (32) are nominally electrically insulated from, and cross, a group of second electrical conductors (48). In particular, a magnetic current-sensing operation is performed on at least part of the conductors to produce current data indicative of how much, if any, current flows through each of at least part of the conductors. The current data is then examined to determined whether there appears to be a short circuit defect at any location where one of the first conductors crosses one of the second conductors.
