Redundant Ring for Substation Automation

Background 


A smart grid substation is composed of intelligent primary equipment such as voltage-meters and secondary equipment such as FTU (feeder terminal unit) and RTU (remote terminal unit). The modern substation enables communication between field secondary equipment and utility’s SCADA system. Reliable and intelligent communication network is a key component to the success of transmission and distribution of electric power to large areas.

 

Because of the special working environment of substations and the requirements of automatic system, the communication network in substation automation system must have:

● High reliablity 

● Data security 

Fast real-time response capability

 Endure harsh environments 



Solution


InHand InSwitch ISM sereis unmanaged industrial switches, featuring industry-leading ring recovery<5ms, providing reliable communications between field devices and utility’s SCADA system.
