Abstract
An improved PCB Rogowski coil addresses the challenges presented by space constraints within circuit interrupters. The disclosed coil comprises a plurality of PCBs that are coupled together, in contrast with known coils constructed from only a single PCB. During a pre-assembly stage, three PCBs are coupled to one another in order to form a partial coil assembly structured to be mounted onto a circuit interrupter primary conductor. After the partial coil assembly is mounted onto the primary conductor, a fourth PCB is connected to the partial coil assembly via press-fit connectors to form a complete coil. In contrast with known PCB Rogowski coils which are structured to be mounted perpendicularly to the primary conductor, the disclosed modular PCB Rogowski coil enables a substantial portion of the PCB surface area to be mounted in parallel to the primary conductor and to thus occupy significantly less space than known PCB Rogowski coils.
