The D60 Line Distance Protection System is provided with an optional phasor measurement unit feature.
This feature is specified as a software option at the time of ordering. The number of phasor measurement
units available is also dependent on this option. Refer to the Ordering section of chapter 2 for additional
details.

monitoring, protection, operation, and control can be realized if Synchrophasors from different locations within the power
system are networked to a central location.
The D60 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
