Differential Protection: Differential protection, commonly deployed in transformers and generators, functions as a specialized safeguard by comparing incoming and outgoing currents within a specific component. This protection scheme relies on differential relays that continuously monitor these currents. If a discrepancy is detected between the incoming and outgoing currents, indicating an internal fault such as a winding short circuit or an insulation breakdown, the relay swiftly identifies this deviation. The relay's response is to isolate the troubled section, preventing the fault from affecting the rest of the system. By promptly isolating the affected area, differential protection minimizes the extent of damage and ensures the continuity of operations within the network. This protection mechanism is particularly effective in swiftly detecting and addressing internal faults, thus contributing significantly to the overall safety and reliability of transformers and generators within the power network.

Distance Protection: This function, primarily utilized in transmission lines, serves as a critical defence mechanism by utilizing distance relays to identify faults based on impedance changes along the line. These relays analyse the impedance variations caused by faults within the transmission line. By comparing the measured impedance to predefined settings, typically expressed as distance zones from the relaying point, distance protection determines the fault location along the line. When a fault occurs and is detected within a specific distance zone, the relay rapidly initiates protective actions to isolate the affected segment of the line while maintaining the remainder of the system in operation. This swift and precise fault localization capability minimizes the impact of faults, facilitating faster restoration and ensuring minimal disruption to the overall network. Distance protection's ability to accurately pinpoint faults based on impedance changes makes it a crucial element in safeguarding transmission lines and ensuring the reliability and stability of the power grid.
