Figure 73 - Typical Circuit Three-Terminal Application

To use TWFL in the case above 3 sets of equipment are necessary: 3(RPV311 +
RA333). One set for each terminal (Figure 74).
In this application, it is necessary to configure two transmission lines in the TW Fault
Locator tool, which means to create two powerline configuration files. The first
powerline configuration file is regarding line A -> B with length and k1 equal to L1 =
L1' + L1'' (Figure 74), and the second powerline file configuration regarding the
section C -> B with length and k1 equal L1'' + L2 (Figure 74).
In order to locate the fault is necessary to combine the fault location of both
situations describe above.
