The G60 is provided with an optional phasor measurement unit feature. This feature is specified as a soft-
ware option at the time of ordering. The number of phasor measurement units available is also dependent
on this option. See the Ordering section of chapter 2 for details.
UR Synchrophasor Implementation
PHASORS are used within protection relays. If these phasors are referenced to a common time base they are referred to as
a SYNCHROPHASOR. A vastly improved method for tracking power system dynamic phenomena for improved power system
monitoring, protection, operation, and control can be realized if Synchrophasors from different locations within the power
system are networked to a central location.
The G60 offers PMU features over two communication standards, IEC61850-9-5 and IEEE C37.118. The figure shows
complete Synchrophasor implementation.

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 standards define synchrophasors and related message formats 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) known as
R-SV.
