The popularity of smart grid technologies for efficient energy management is being driven by the simultaneous increase in energy consumption and the large investments being made in infrastructure projects across different regions.
Introduction
A protective relay is a type of switchgear that identifies any issues in the electrical power grid and swiftly initiates the operation of the circuit breaker to separate the faulty part from the rest of the system. It is placed in the electrical system to oversee any irregular or defective situations in the circuit. Protective relays are crucial elements of contemporary electrical systems and are vital for safeguarding these systems. Protective relays identify faults or hazardous conditions and trigger the most suitable actions to avert damage and guarantee the safety of equipment and personnel. A protective relay is an intelligent device that gathers inputs, contrasts them with predetermined values, and provides output. The electrical parameters or inputs that can vary in faulty situations include current, voltage, power, frequency, pressure, temperature, flow, and vibration. Protective relays in the electrical system ensure a continuous electrical supply. Protective relays help minimise harm to electrical components and equipment during electrical failures. The rising demand for smooth and effortless electrical service has resulted in a greater need for protective relays within the electrical system.
