Synchronization using IRIG-B
Example of IRIG-B synchronization
The IRIG-B method is possible when a synchronization signal in the IRIG-B format is provided.
The synchronization signal is transferred using the IRIG-B000 module†.

Setting procedure
The user should make the following steps in respective IEDs.
1) Set
IRIG-B
for the setting [
Time Sync Src
]; then set
On
for the setting [
IRIG-SYNC
].
2) Check that the
IRIG-B
is shown under the ActivSyncSrc, as shown in Figure 5.7-6.

Setting year in IRIG-B
When the IRIG-B data is generated in the IEEE C37.118 / IRIG-B000 format, the user should
set
On
for setting [
USE_BCDYEAR
]. Conversely, when the IRIG-B data with absence the
C37.118† is generated,
Off
should be set for the setting [
USE_BCDYEAR
].
†Note: “Year” is informed from the IED clock itself when the C37.118 is absent.
Setting UTC/local time
When the IRIG-B data is generated in the UTC†, set
Off
for the setting [
USE_LOCALTIME
].
Conversely, when the IRIG-B data is generated in the local time‡, set
On
for setting
[
USE_LOCALTIME
]; set
Off
for the setting [
IS_UTC_base
].
†Note: We shall see the settings of the UTS in section 5.7.4.
‡Note: In the IRIG-B signal generator unit, the DST settings should be corresponded to
the DST settings of the IED. We shall see the DST settings in section 5.7.5.
