The IEEE standard for protection relays refers to a collection of guidelines developed by the Institute of Electrical and Electronics Engineers. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. These types of devices protect electrical systems and components from damage when an unwanted event occurs, such as an electrical. IEC 60255-1:2022 specifies common rules and requirements applicable to measuring relays and protection equipment, including any combination of equipment to form a distributed protection scheme for power system protection such as control, monitoring and process interface equipment, to obtain. Protection relays are the backbone of modern power systems. Also principles of various protective relays and schemes including special protection.
