How to connect protection inputs to relay protection
The objective of relay protection is to quickly isolate a faulty section from both ends so that the rest of the system can function satisfactorily.

The preparedness of relay protection refers to
Relay protection is the discipline of designing schemes that detect faults, coordinate relays, and isolate equipment without outages. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.

Function of Line Relay Protection
They act as the first line of defense by detecting and isolating faults or abnormal conditions on power lines to prevent damage to equipment and ensure the safe and reliable operation of the network.
