Build systems that prevent hazards and quantify performance—over/under-voltage, overcurrent/earth-leakage, surge/arc protection, temperature/speed/vibration monitoring, and gas/smoke/fire detection. Develop relay- and MCU-based protection (MCB/ELCB/RCD, differential/overcurrent), power/energy meters, calibration rigs, and IoT alert dashboards with logs. Learn fault detection, isolation, and standards-aligned testing. Ideal for diploma/BE final-year—kits include parts, code, circuit, report, and support.
