This work is of high practical importance to the society and country in general. The selected protection principle affects the operating speed of the protection, which has a significant im-pact on the harm caused by short circuits. Further, the duration of the voltage. ABSTRACT: Relay coordination is a means by which a relay closest the point of fault operates, but in the event of failure the backup relay operates in sequence to provide backup protection. It involves the use of protective relays to detect abnormal conditions, such as faults or disturbances, and initiate appropriate actions to isolate. The first uses a powerful but traditional approach with a microprocessor relay, the second a point-to-point (P2P) process bus architecture, and the third a process bus solution based on the IEC 61850 standard.
