The Synchrophasor Stream Splitter is used to generate multiple data streams from a single synchrophasor stream source. This service based application consumes an incoming stream of synchrophasor data (e.g., from a substation with limited bandwidth where sending multiple streams would be impractical) and redistributes the stream as many times as needed.

All common synchrophasor protocols are supported (e.g., IEEE C37.118, IEC 61850-90-5, F-NET, SEL Fast Message, Macrodyne and BPA PDCstream). This tool does not disaggregate streams into points - it resends exactly what was received. Manager and console applications can be run remotely - active configuration can be downloaded, edited and uploaded from management tool. Configuration is stored as an XML file. Full support for incoming and outgoing UDP, TCP, IPv6, and IPv4 in all combinations.

For TCP proxy point, configuration frames are cached and sent to clients upon request. For UDP rebroadcasts, configuration frames will automatically be sent once per minute unless source connection is already doing this.

Using multiple instances of this service can allow you to safely traverse security zones with synchrophasor data by making sure connections are initiated from the higher security zone regardless of the direction of data flow.
