Smart Ethernet Switch for Digital Substation

NR Electric has released the industrial-level PCS-9882 Ethernet Switch for the applications in digital substation. Function modules are designed based on the unique time tag to prevent mal-operations caused by the loss of external GPS signals. By using the static multicast management, data network traffic can be optimized. VLAN technology is introduced to achieve logically independent duplicated networks at different voltage levels.

Data flows are controlled by sorting MAC addresses and protocol types so as to avoid influences of network storms. The PCS-9882 Ethernet Switch has passed IEC61850 Level A test conducted by KEMA.
