An example of the use of sources is shown in the following figure. A relay can have the following hardware configuration:
UR
B30, B90, C70, F35, N60, T35
C60, D60, G30, G60, L30, L90, M60, T60
This configuration can be used on a two-winding transformer, with one winding connected into a breaker-and-a-half
system. The following figure shows the arrangement of sources used to provide the functions required in this application,
and the CT/VT inputs that are used to provide the data.
