Role of Circuit Breakers, Fuses, and Protective Relays in Electrical Safety – MISP-21

Electrical systems play a crucial role in modern industries, residential areas, and commercial establishments. However, with the growing complexity of electrical networks, ensuring safety and reliability has become a top priority. This project titled “Role of Circuit Breakers, Fuses, and Protective Relays in Electrical Safety” explores the significance of these essential protective devices in preventing electrical accidents, equipment damage, and power system failures.

The study focuses on how circuit breakers, fuses, and relays function as vital components in fault detection and interruption mechanisms. It explains how they protect electrical systems against overcurrent, short circuits, voltage fluctuations, and ground faults. Additionally, the project highlights the comparative advantages of modern protective technologies such as digital relays and smart breakers used in automated systems.

By analyzing real-world case studies and technical standards, this project helps students understand how effective protective coordination ensures system stability, operational safety, and equipment longevity.
