Condition logic (Signals 'ARC1_SPAR_COND', 'ARC1_TPAR_COND')

The 'Condition' logic issues the above signals depending on the setting [ARC1 MODE] and the

tripped phases (i.e., signal 'TRIP-ANYPH' and others). This logic is available when the setting

[ARC1 MODE] = SPAR, TPAR, or SPAR&TPAR.

Link judgment (setting MPAR-MODE and signals 'MPAR_LINK')

With regard to the power transmission between terminals, the 'Link judgment' logic issues the

healthy phases that are left during a fault in parallel lines. This logic is available when the

settings [ARC1 MODE] = MPAR and [ARC-MANOLK] = TPAR or SPAR&TPAR.
