IRIG-B00X
IRIG-B
Requirement: An IRIG-B00X time code generator is needed. IRIG-B004 and
higher will support/transmit the “year information”.
If you are using an IRIG time code that does not support the “year information”
(IRIG-B000, IRIG-B001, IRIG-B002, IRIG-B003), you have to set the “year”
manually within the device. In these cases the correct year information is a
precondition for a properly working IRIG-B.
Principle - General Use
The IRIG-B standard is the most used standard to synchronize the time of protection devices in medium voltage
applications. The protection device supports IRIG-B according to the IRIG STANDARD 200-04.
This means that all time synchronization formats IRIG-B00X (IRIG-B000 / B001 / B002 / B003 / B004 / B005 / B006 /
B007) are supported. It is recommended to use IRIG-B004 and higher which also transmits the “year information”.
The system time of the protection device is being synchronized with the connected IRIG-B code generator once a
second. The accuracy of the used IRIG-B code generator can be increased by connecting a GPS-receiver to it.
The location of the IRIG-B interface depends to the device type. Please refer to the wiring diagram supplied with the
protective device.
