Under the guidance of Schneider Electric, this Major Qualifying Project aimed to replace traditional inductive coils in ground fault and arc fault circuit interrupters. The project sought to utilize resistive shunts or other sensing components for fault detection. The team designed, simulated, and constructed a successful prototype that employed metal film shunt resistors for ground fault detection and a ferrite bead serving as an inline inductor for arc fault detection. Additional consideration was given to the thermal behavior of the sensing components using an infrared camera. Testing demonstrated that a thermal differential between components will not cause erroneous tripping of the breaker.
