Figure 2.32-5 shows a trigger signal for data recording. Respective elements of protective

functions (ZS/ZG, OC, and DIFL) output their operation signals when respective elements

operate; and then, these signals are summarized to the trigger signal by a logic "OR". In

response to scheme switch [FL-Dir], the FL can record the data of current and voltage if the

fault occurs in either forward or reverse.
