Perform power system simulations of selected faults and observe how a given protection principle (overcurrent, impedance, and differential) works. Set the relays for a given power system. Verify by
LECTURE NOTES ON ELECTRICAL POWER SYSTEM
For operation of CB a relay is necessary. A protective relay is a device that detects the faults and initiate the operation of the circuit breaker to isolate the defective element from the rest of the system.
POWER SYSTEM PROTECTION
Protective relays and schemes are essential components of electrical power systems, designed to detect and respond to abnormal conditions to protect equipment and ensure system reliability.
