Protection Signaling Equipment (PSE) forms the critical communication backbone for transmission line protection schemes in modern power systems. This technical guide explores the migration from legacy Digital (E1/G.703) interfaces to Optical Ethernet interfaces over MPLS networks, explaining the technical rationale, implementation challenges, and practical considerations for utilities and EPC contractors. This guide provides comprehensive technical…

Feeder Protection Signaling
High-voltage power systems like 380kV transmission lines are the backbone of modern grids. They carry electricity over long distances, and any fault (like a short circuit or flashover) the system must detect it instantly and isolate it to protect equipment and keep the grid stable. That’s where feeder protection signaling comes in. In this post,…
