Table 2.34-2 summarizes the reclosing operations and the modes in the ARC function. The

ARC function can operate for both a single CB arrangement and double CBs (1.5CB)

arrangement; hence, the ARC function is grouped into two logics: ARC1 for CB#1 and ARC2

for CB#2. Note that multi-shots scheme is only available for 1CB arrangement (CB#1). The

'ORIGINAL' is provided for the user's programing.

Operation is applicable

Breaker system

The ARC function can operate in several breaker systems, as shown in Figure 2.34-1. For the

1.5CB arrangement, the ARC1 and ARC2 logics operate separately; the user can select

different reclosing scheme (Figure 2.34-1.b). In parallel lines, the ARC function can take

several reclosing schemes when the communication application (COMM_APPL) is available

(Figure 2.34-1.c).
