| Description:
Responsible for standardPC37.238 that specifies
a common profile for use of IEEE 1588-
2008 Precision Time Protocol (PTP) in
power system protection, control,
automation and data communication
applications utilizing an Ethernet
communications architecture. The profile
specifies a well-defined subset of IEEE
1588-2008 mechanisms and settings aimed
at enabling device interoperability, robust
response to network failures, and
deterministic control of delivered time
quality. It specifies the preferred physical
layer (Ethernet), higher level protocol used
for PTP message exchange and the PTP
protocol configuration parameters. Special
attention is given to ensuring consistent and
reliable time distribution within substations,
between substations, and across wide
geographic areas.
