IEC 60255-187-2, Functional requirements for busbar differential protection Protecting the smart grid: IEC 60255-181:2019 In 2012, an ad hoc
Protective relays are critical in power systems because they serve as decision-making devices that ensure the safe operation of power grid. They play a key role in power system protection.
Traditionally, protective relays were electromechanical devices utilizing induction disk, coils, contacts, and solenoid elements to determine protective characteristics.
