Using their exclusive interface design of 7+3G combo ports and the RSR ring redundancy technology, the switches provided connectivity to cameras and assured reliable high-speed video transmission to the remote location without causing data failure or loss. Through their smart firmware functionalities and the ruggedized design with -40~70°C wide operating temperature, the switches resisted the extreme conditions on electrical utilities while providing high performance video surveillance of the field sites.
Surveillance of electrical substation facilities becomes of higher importance today as it enables utility workers to operate more efficiently while remotely monitoring substations for safety and maintenance and helping prevent accidents such as electrocution around electrical facilities and downed power lines. Thus, receiving real-time video of the substation plants' operation is crucial when designing utility automation system. Substations are widely distributed; therefore extended fiber connectivity is often required to ensure longer distance data transmission. Besides, as the conditions around utilities are unfavorable with temperature variations, high level of electromagnetic radiation, equipment with increased rigidity are required to operate without system failures.
An electrical substation company in Russia, a trustworthy partner of PLC Systems (Korenix's diamond distributor) chose to use JetNet 5010G series managed gigabit switches for their guaranteed connection reliability, easy maintenance and unique, flexible and cost-saving interface design.
Around 300 JetNet 5010G-w gigabit switches have been installed on sites of substation facilities. Using 7 Fast Ethernet ports the switches connected to video cameras to collect the captured images from a selected field. Using 2 out of 3 Gigabit SFP Combo ports, the switches were able to connect with each other and using the Korenix Rapid Super Ring technology, form redundant Gigabit fiber rings by the connected SFP transceivers. With the RSR technology which provides only 5ms recovery time and seamless restoration, the video streams were transmitted reliably without packet loss, topology change and data transmission latency.
The switches also were noticed for their intelligent firmware capabilities. The LLDP which is integrated in the switch and the Korenix's JetView Pro software provided users with easy maintenance, as they enabled them to discover and manage all the connected JetNet 5010G-w devices in the network infrastructure automatically from the remote location. Besides, to improve the data transmission performance, the switches also used the QoS for data prioritization, IGMP snooping for one-to-many video transmission, VLAN for video traffic isolation, etc.
Last but not least, the ruggedized enclosure of the JetNet 5010G-w has been another most important factor for the system installing company to choose Korenix. The IP31 grade design as well as -40~70°C operation range provided resistance against vibration, shock and temperature variations ensuring users that they can operate under harshest conditions - something that is typical in substations.
With intelligent firmware and software features and exclusive interface design, the switches became the perfect cost-effective solution for reliable video surveillance of this electrical substation.
Why JetNet 5010G for Electrical Substation Surveillance:
