9.5 Verifying the communication
GUID-D10769FC-6C70-48A3-A1D8-FAFCCA82A3BE v2
Connect your PC to the substation network and ping the connected IED and the Substation Master
PC, to verify that the communication is working (up to the transport layer). Make sure that the optical
fibers are connected correctly.
After checking the communication, it is time to verify the IEEE C37.118/1344 communication over
both TCP and UDP protocols.
One way to verify the communication up to the application layer is to use a protocol analyzer
connected to the substation bus, and monitor the communication. Alternatively, the PMU Connection
Tester tool can be used to verify the IEEE C37.118/1344 communication. The section
Setting the
TCP/UDP client communication explains how to set the PMU Connection Tester parameters in order
to establish an IEEE C37.118 connection with the PMU.

GUID-289E2E92-431E-45FE-B586-A723588B98A1 v1
After setting both PMU configuration and the TCP client configuration (As explained in sections
Setting the PMU station communication (PMU Report), Setting the PMU station communication
(PMU configuration) and Setting the TCP/UDP client communication) and making sure that the
Ethernet communication is set up, click Connect on the PMU Connection Tester tool.

• Now it should be possible to see the streaming synchrophasor data. In the Graph tab, observe
the Frequency, data Reporting Rate, Phasor names, and Phase angles of the reported
synchrophasors. Observe the real-time frame details of the Data Frame in the bottom of the
window.
