Directional relays play a critical role in power distribution systems, ensuring proper fault detection and isolation while maintaining system stability and reliability. These relays are particularly useful in complex networks where power flow can change direction, such as ring mains, parallel feeders, or interconnected grids.
In modern electrical power systems, integrating Low Voltage (LV) boards with Supervisory Control and Data Acquisition (SCADA) systems is essential for efficient real-time monitoring and control. This process enhances system reliability, optimizes energy usage, and improves operational decision-making.
