Abstract
Electrical power systems are prone to faults that can cause equipment damage, service interruption, and safety hazards. Protection schemes are designed to detect abnormal conditions and isolate faulty sections, ensuring reliability and safety. This paper reviews major protection schemes in power systems, including overcurrent, differential, distance, and busbar protection, as well as relaying techniques and coordination strategies. Circuit models, relay configurations, and fault analysis methods are discussed with supporting tables and figures. The paper emphasizes the integration of protection schemes in modern smart grids and their importance in maintaining power system stability and reliability.
KEYWORDS: Power system protection, relays, fault detection, overcurrent, differential protection, distance protection, coordination
