Abstract
A current source is applied on the two diagonal corners of a power plane. By changing the current source to another pair of opposite corners, one can determine the associated zero voltage contour line. The intersection of the two zero voltage contour lines locates the position of the short fault. An analytical formula has been derived to give the potential distribution for the plane with rectangular shape. Excellent agreement with the exact short point validates the present inspection approach.>
