In a power system, what does the term 'protection relay' refer to?

Step 1: Understand that a power system is a network that delivers electricity.
Step 2: Know that faults are problems in the electrical system, like short circuits.
Step 3: Learn that protection relays are special devices used in power systems.
Step 4: Realize that these relays monitor the electrical system for any faults.
Step 5: When a fault is detected, the protection relay sends a signal.
Step 6: This signal tells the circuit to stop the flow of electricity.
Step 7: Stopping the electricity helps prevent damage to the system.
