Single-Phase Smart Protection Unit for Domestic Loads. Electrical Fault Protection

Bachelor Thesis , 2019 , 39 Pages , Grade: A

Engineering - Power Engineering

In Domestic Electrical Power Systems, protection schemes are essential for the protection of equipment and lives, as well as for providing a reliable and continuous supply of energy. In this thesis, a single-phase fault protection unit for domestic loads is proposed. This proposed scheme uses intelligent components, mainly: a microcontroller, Global System for Mobile Communication (GSM), relay, current transformer, and circuit breaker to implement a smart electrical fault protection system.

The design is simulated and analyzed with the Proteus Design Suit Software, and a prototype is designed and tested. The successful implementation of the smart protection system prevents damage to domestic appliances.
