Synchronizing more than 20 SIPROTEC 3 Devices
Here, the use case presented in chapter
3.4 Synchronizing more than 12 SIPROTEC 4 or SIPROTEC 5 Devices
expanded with additional SIPROTEC 3 devices. The minute pulse arriving at R1 is, in this case, also decoupled
by way of the electronic load disconnecting relay (K2) and forwarded to the protection devices.

NOTE
In this application, the battery of the plant that you connect to the contacts marked L+ and L- must be
integrated (connected in series to the switch of the electronic load disconnecting relay K2). Set the switch
threshold values for the binary inputs on the SIPROTEC 3 devices according to the battery voltage of the
plant.
