Choosing the correct protection relay for your MV application is not just about brand—it’s about matching functionality with your system’s risk profile. Directional overcurrent protection, earth fault, differential protection, and recloser logic all serve different roles.
At OXCART, we implement modern relays from brands like Siemens (SIPROTEC), Schneider (Easergy), and ABB (Relion) depending on system requirements. Our selection is based on IEC 61850 compliance, scalability, and interoperability with SCADA systems.
This blog explains the difference between electromechanical, digital, and numerical relays, and how to create coordination curves for system selectivity. Learn how proper relay selection reduces false trips, improves fault clearance time, and enhances system resilience.
