Application Manual
The second part of the function invokes the basic autorecloser function, which determines
whether / when to reclose / lockout etc.
The third part of the function distributes the autorecloser outputs to the phases currently
active, as determined by the first part of the function. Outputs from the function consist of
per phase breaker open / close commands, and lockout signals.
3.4.3 Input function blocks (SDAIGGIOs)
The input section, consists of six modular supporting functional blocks called
SDAIGGIOs, collates various signal phase trip / pickup signals from different single phase
protection functions. It uses the logic described below to determine which phases are to be
activated for this reclose cycle, and tailors its outputs to be fed to the autorecloser / output
functions.
