monitoring, protection, operation, and control can be realized if Synchrophasors from different locations within the power
system are networked to a central location.
The T60 offers PMU features over two communication standards, IEC61850-9-5 and C37.118. The complete Synchropha-
sor implementation for Firmware version 7.0 is shown in the figure below.

UR Implementation of IEC61850-90-5
Synchrophasor data as measured and calculated by phasor measurement units (PMUs) is very useful to assess the condi-
tion of the electrical power network. The IEEE C37.118-2005 standard defines synchrophasors and related message for-
mats to transmit synchrophasor data. Synchrophasor streaming via IEEE C37.118 has proven to work but the desire to
have a communication mechanism that is compliant with the concept of IEC 61850 has led to the development of
IEC61850-90-5. The IEC61850-90-5 standard defines the packet structure for multicast routing of streamed Sampled Value
(SV) and GOOSE messages known as the R-SV and R-GOOSE respectively.
