Feature

Overview

Accurate and timely information is essential for power distribution system control. EtherWAN provides a product line of serial converters and Ethernet switches that provide reliable communications systems for this application, as shown in the following example: FDCC (Feeder Dispatch Control Center) is connected through communication devices to FRTU (Feeder Remote Terminal Unit) in each substation and then connected to FTU (Feeder Terminal Unit) on different distribution lines. FTUs deliver the communication status and electricity distribution data back to the FRTU and all of the collected information will be returned to the FDCC.

When an outage occurs in the distribution system, dispatchers need to know precise locations in order to fix the problem in a timely manner. However, if a connection fails important information will not be transmitted to the FDCC. EtherWAN’s FT5702 2-port RS232/422/485 Fiber Modem provides the reliability of uninterrupted serial to Ethernet communications, because of its Self-Healing Ring feature. The FT5702 offers single-mode or multi-mode with SC, ST, plus WDM fiber optic options for both LAN ports and an alarm relay that indicates the occurrence of any disconnect.

EtherWAN’s FT5702 is tested and compatible with IED equipment manufactures such as SIEMENS, ABB, SEL, GE…etc. The FT5702 also supports DNP 3.0 protocol transparency.
