Synchrophasors Directory
Table 15.15 shows an example SYNCHROPHASORS directory. Synchrophasor
data recording is enabled when synchrophasors are enabled and EPMDR := Y.
The filename includes a time stamp based on the first data frame in the file. The
data in the file conforms to the C37.118 data format.
Software Protocol Selections
The relay supports the protocols and command sets shown in Table 15.16.
C4_10001.TXT 4-samples/cycle Compressed ASCII event report; read-only
C8_10001.TXT
a
8-samples/cycle Compressed ASCII event report; read-only
E4_10001.TXT 4-samples/cycle event report; read-only
E8_10001.TXT
b

a
In the SEL-487B, this is replaced with C1210001.TXT which provides a 12-samples/cycle Compressed
ASCII event report.
b
In the SEL-487B, this is replaced with E1210001.TXT which provides a 12-samples/cycle event report.
