Power-Grade Switches Demystified — IEC 61850-90-4 Essentials at a Glance

Physical Layer: Security & Reliability

IEC 61850-3 / IEEE1613

• Electromagnetic Compatibility (EMC): High immunity to interference
• Environmental Resilience: Withstands high temperatures, vibration, and harsh conditions
• High Reliability & Stability: Designed for substation-grade environments

Network Layer: Interoperability & Stability with

IEC 61850-3-90-4

• Network Topologies: Supports star, ring, dual-network architectures
• PTP (IEEE 1588v2): Precise time synchronization for accurate event timestamping
• GOOSE / SV Transmission: Supports multicast and low-latency communication

EtherWAN Technology IG5 Rack Series、 IG5 L Rack Series、 IG5 SV Seriesare 10G Ethernet switches designed to meet power plant standards, ideal for on-site device connectivity. The IG5 SV Series also supports PoE terminal connections, a rare feature in the industry.
In energy storage applications, these switches work with system-level warning and protection mechanisms to improve grid dispatch flexibility and stability. They comply with IEC 61850 communication standards and EMC requirements for substations, enabling smarter grid protection and management. The 10G backbone network supports high-volume data transmission and ensures secure, reliable, and stable operation through its rugged design and redundancy features.
