The protection system operates to isolate faulty sections of the electric grid to reduce <br />damage and disturbance to the balance of the system and to ensure safety to the public and staff. <br />Over the last two decades, the digital revolution made a significant impact on the electric power industry, <br />including the development and advancement of protective relays (relays) and automation equipment in <br />electrical substations. Consequently, there has been a migration from electromechanical relays towards <br />microprocessor -based relays and controls. This has been the case since electromechanical relays are <br />prone to electrical and mechanical failures, require frequent maintenance, and have setting limitations <br />compared to microprocessor -based relays. Microprocessor -based relays perform the same protection <br />operations, but with higher precision, reliability, and transparency. The complexity of protection schemes <br />
