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

Secure Physical Layer

IEC 61850-3 / IEEE1613

• High-immunity EMC against interference.
• Withstands heat, vibration, and harsh conditions.
• Substation-grade reliability and stability.
 

Resilient Network Layer

IEC 61850-90-4

• Star, ring, and dual-network topologies.
• PTP (IEEE 1588v2) precise time sync and accurate timestamps.
• GOOSE/SV multicast, low-latency messaging.

EtherWAN’s IG5 Rack Series、 IG5 L Rack Series、 IG5 SV Series are 10G Ethernet switches designed to meet power plant standards, ideal for on-site device connectivity. The IG5 SV Series also provides PoE for terminal devices, a rare feature in the industry.

In energy-storage deployments, these switches integrate with system-level alarms and protection to enhance dispatch flexibility and grid stability. They comply with IEC 61850-3 and substation EMC requirements , enabling smarter grid protection and operations. A 10G backbone moves high-volume data , while rugged construction and built-in redundancy help ensure secure, reliable, and stable operation.
