Korenix Substation-rated JetNet 5628G Exceeds the IEC 61850-3
& IEEE1613 Standards for Power Substation Applications!

Substation utilities continuously encounter the challenge of providing reliable power to the end-users. Due to several reasons, such as equipment failures, unfavorable environmental conditions and accidents, power disturbances and outages in substations occur and often result in long service interruptions. Thus, substations should be properly controlled and monitored by networking systems to provide a high reliability, availability of substation communications under critical environmental conditions.

IEC61850-3 / IEEE1613 Outstanding Requirements for Power Substation Control and Protection
In substation environments, there are many EMI & Environmental Phenomena, such as electric, magnetic interference, high energy power surge, lightning strikes, electrostatic discharges, vibration, shock etc. which may cause errors or equipment damage in electronic communications. Besides, the climatic conditions found in substations can be extremely varied. The monitoring rooms of substations may be sheltered from some climatic threats such as, wind, rain, but there are often no climatic controls for temperature. Thus, networking devices within these environments must be capable of  operating reliably across a highly variable and uncontrolled temperature and humidity.

When it comes to Ethernet network construction for substation automation, the utility companies generally require the IEC 61850-3 and IEC 1613 compliant networking devices. The IEC 61850-3 and IEEE 1613 standards specify environmental and EMI immunity requirements for providing error-free network equipment operation in substations. IEC61850-3 defines the standard for the "Communication Networks and Systems in Substations", whereas IEC1613 defines the “Standard Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations”.

To construct flexible Ethernet network in substation environments with long and mid-range distance transmission, most substations also require using fiber and/or copper cabling. For short distance Ethernet interconnectivity, copper is being used as a way of cabling, whereas for remote transmission throughout large substation areas fiber is given priority to. Hence, utility administrators generally require using a mixture of these cabling types for providing long-haul, high speed and high bandwidth transmission. In highly critical substation environments, the networking devices should provide reliable data transmission without data loss or collision. Therefore, a network redundancy is a must in utilities for ensuring high network reliability. At last, for substation use, there are a least of management and security requirements that switches must provide, including Multicats filtering, QoS, VLAN, Access Control List etc.

JetNet 5628G series Exceed the IEC 61850-3 & IEEE 1613 standards
Korenix JetNet 5628G Gigabit modular managed switches have successfully passed all required tests for communications networking devices in substations and obtained the highly valuable IEC61850-3 and IEEE1613 environmental certifications.

Korenix substation hardened switches further provide even more advanced operation with  their outstanding design and management features. Equipped with 3 modular slot design, they provide users with maximum flexibility through easy field installation in power utility substations. The switches provide patented MSR technology and can recover link failure in just 5 milliseconds. With the exclusive MultiRing technology, users can aggregate up to 12 fast Ethernet and 2 gigabit rings into a single switch and ensure network reliability in applications with increased bandwidth and expended system.

JetNet 5628G has the capability of forwarding Data, GOOSE, SCADA message without any loss or collision and supports the IEEE 1588 Precision Time Protocol for providing precise time synchronization.

Furthermore, JetNet 5628G fulfills the high-end management requirements of IEC61850-3 substation standard by providing LLDP and JetViewPro, 8 QoS, 256 VLAN, IGMP Snooping, DHCP, LACP, and other advanced management and security features to ensure the high quality and reliable network communication.
