External selection of auto-reclose mode

The auto-reclose mode can be selected by use of the available logic function blocks. Below is
an example where the choice of mode is done from a hardware function key in front of the IED
with only 3 phase or 1/3 phase mode, but alternatively there can for example, be a physical
selector switch on the front of the panel which is connected to a binary to integer function
block (BTIGAPC).
The connection example for selection of the auto-reclose mode is shown in figure 112.

given.

Pulsing of the CB closing command and Counter

The CB closing command, CLOSECB is given as a pulse with a duration set by parameter
tPulse . For circuit-breakers without an anti-pumping function, close pulse cutting can be used.
It is selected by parameter
command pulse is then cut (interrupted). The minimum closing pulse length is always 50 ms.
At the issue of the Reclosing command, the appropriate Reclosing operation counter is
incremented. There is a counter for each type of Reclosing and one for the total number of
Reclosing commands.
