ABSTRACT:
A method for detecting and locating constrictions in electrical conductors of predetermined normal cross-section. A test or reference resistance reading is made and stored pursuant to application of a test current, a stress current is applied, heating any constriction in the conductor, a resistance reading is taken immediately after the heating has taken place and the respective resistance readings are compared to determine the presence or absence of a constriction or weak spot. The disclosure also includes an exemplary circuit to implement the method. In an alternative embodiment, a second test current is applied immediately after the stress current.
