CrispTech is an Australian distributor of industrial communications products and national distributor of Moxa products. They discovered that the reliability or Moxa's IEC-61850-3 Ethernet switches that was suitable for their demanding power distribution requirements. Moxa's PowerTrans PT-7828 and PT-7710 series Ethernet switches are specifically designed to operate reliably in varying electric utility substation environments. The entire product line has passed IEC 61850-3 and IEEE1613 certification testing conducted by KEMA, a well-known independent laboratory for consulting, one-stop testing and certification services in the energy and utility markets.
Electric power distribution is the final step in the delivery of electricity to consumers. A typical distribution system consists of a complex power utilities network, with correspondingly complex wiring requirements. Moxa’s breakthrough TurboChain redundancy technology simplifies the creation of multiple redundant connections over a widely dispersed power distribution network. With TurboChain, PowerTrans Ethernet switches can be daisy chained together from one Ring Main Unit (RMU) to another, with each chain connected to the substations. If a chain segment fails, the blocked path will rapidly activate within 20 milliseconds for high network availability.
The PowerTrans PT-7828 layer 3 Ethernet switches also support Open Shortest Path First (OSPF), which uses link state instead of hop count to determine the network route. Guangzhou's DA project was able to reduce wiring costs and increase network efficiency by taking advantage of the PowerTrans series powerful suite of features
