Voltage selection for line arrangement

As shown in Figure 4.6-16, input-voltage signals are required in response to the line and bus-

bar arrangement. Incidentally, the input-voltage signals supplied by the VTs are applied to the

IED via the transformer module (VCT†); hence, the input-voltage signal should correspond

with the required relay-element. On this account, settings are provided in the SYNCHK_Ry

Figure 4.6-18 Voltage signals selected using scheme switches

†Note: For the actual terminal arrangement and signals injected, see chapter

description: Transformer module for AC analog input.

Figure 4.6-18 illustrates that the signals injected are distributed using scheme switches:

[SyncRy1-VR], [SyncRy1-VI], [SyncRy1-VR], and [SyncRy1-VI]. Examples below show how to

apply a voltage signal for the required relay-element.

Setting example

Figure 4.6-19 depicts an example of a busbar arrangement and S43P logic programmed by the

user. In this case, only the SYNCHK_Ry1 function is used; therefore, the user need only select

the signal provided by the S43P logic for the SYNCHK_Ry1 function.
