Abstract:
This project presents the design and implementation of an automated low-voltage power
distribution line monitoring and alerting system aimed at improving fault detection, reporting, and
response time in Uganda’s power distribution network for the undeserved regions. The system
leverages an Arduino-based microcontroller integrated with current sensors (ACS712), a voltage
divider circuit, and a SIM800L GSM module to detect and report key anomalies such as outages,
short circuits, and phase imbalances in real time. Transformer loading and efficiency were also
calculated periodically to assess performance and support preventive maintenance. Alerts were
displayed locally using a 16x2 LCD and remotely via SMS. The system was simulated in Proteus
and validated through hardware testing under various fault conditions. It offers a low-cost, scalable
solution to enhance grid reliability in underserved areas, aligning with national electrification
goals.
