Departmental Laboratory

The Power System Protection Laboratory at Green University equips students with comprehensive insights into the principles and technologies of modern electrical protection systems. Through advanced experiments, students explore the operation of under/over-voltage, current, and frequency protection schemes essential for grid stability. The lab includes hands-on training in alternator synchronization with phase sequence protection and transformer thermal monitoring using sensor-based systems. Students delve into the characteristics and coordination of protective relays, including Inverse Definite Minimum Time (IDMT) relays, both in hardware and Simulink-based environments. Real-time simulation of three-phase fault detection and symmetrical/unsymmetrical fault analysis in MATLAB/Simulink enhances analytical proficiency. The laboratory also emphasizes automation through the study of auto reclosers and microprocessor-based power factor improvement (PFI) units.
