Abstract
A method and apparatus for simultaneously measuring current flows through fasteners in a multi-structure composite joint is provided. The method comprising inserting a printed circuit board between at least two structures, the printed circuit board being etched with at least one Rogowski coil sensory circuit the at least two structures being joined with at least one fastener extending through the at least one Rogowski coil sensory circuit in the printed circuit board; detecting current in the at least one fastener; transmitting the detected current from each fastener to a corresponding passive integrator circuit for capturing transient pulses and integrating the pulses into an output; and transmitting the output to a processing unit.
