FaultFinder — Intelligent Low-Voltage Grid Monitoring PCB

Report
Designed the complete PCB architecture for FaultFinder, a compact field-deployable device for real-time fault detection and localization on 240 V AC low-voltage distribution networks. Developed the high-speed analog front-end with a non-contact TMR current sensor, dual wireless connectivity, onboard AI signal processing, AC-DC power conversion, battery management, and protection circuitry. Designed entirely in KiCad, including detailed 3D modeling for connector alignment and mechanical integration.
