IEEE C37.118 Synchrophasor Protocol (synphasor)

The transmission format defined by IEEE C37.118 for reporting synchronized phasor measurements in power systems.

Protocol dependencies


The Wireshark dissector decodes synchrophasor frames as defined by IEEE C37.118-2005. Where the standard is ambiguous, the recommendations by the Power System Relaying Committee WG H11 are used. The dissectors tries to find the correct configuration frames and uses them to decode the data streams.

Preference Settings

The TCP and UDP ports the dissector is listening to can be changed in the protocol preference dialog.

Example capture file


Display Filter

A complete list of PROTO display filter fields can be found in the display filter reference.

Capture Filter

You cannot directly filter PROTO protocols while capturing. However, if you know the TCP port used (see above), you can filter on that one.
