ABB 500PSM03 Line distance protection relay

ABB 500PSM03: Product Overview

The 500PSM03 is a line distance protection relay from ABB’s REL 500 series, designed for high-voltage transmission and distribution networks. This advanced relay provides distance protection, fault detection, and automation control for overhead lines and cables, ensuring grid stability and minimizing outage times. It is widely used in substations, renewable energy plants, and industrial power systems to safeguard against phase-to-phase and phase-to-ground faults, while supporting compliance with stringent grid codes.
