Synchronizing up to 20 SIPROTEC 3 Devices
In this application example, the hardware configuration is nearly identical to that in chapter
more than 12 SIPROTEC 4 or SIPROTEC 5 Devices
. At 20 (2 × 10), only the number of protection devices that
can be connected is higher because the SIPROTEC 3 inputs put less of a load on the Sync-Transceiver switching
output. SIPROTEC 3 devices do not have a separate time-synchronization input. Instead, they use the binary
inputs for this. In addition, SIPROTEC 3 devices, in contrast to SIPROTEC 4 or SIPROTEC 5 devices, only process
minute pulses.

NOTE
Set the switching threshold values of the binary inputs at the SIPROTEC 3 devices to the lowest value
because the drive level is only 24 V due to the Sync-Transceiver.
