PTP provides high-accuracy timing over an Ethernet network. ► Digital Relay-to-Relay Communications. Enhanced Mirrored Bits® communications can monitor internal element conditions between bays within a station, or between stations, using SEL fiber-optic transceivers. The relay shall support Precision Time Protocol version 2 (PTPv2). The Ethernet network and all traffic are fully duplicated with both copies operating in parallel. ► IEEE 1588, Precision Time Protocol. Provide seamless recovery from any single Ethernet network failure, in accordance with IEC 62439-3. Connect to substation or corporate LANs to transmit synchrophasors in the IEEE C37.118–2005 format by using TCP or UDP Internet protocols. Use file transfer protocol (FTP) for high-speed data collection. Interconnect with automation systems by using IEC 61850 or DNP3 protocol directly.
