Operation principle
11.3.6.1
Auto-reclosing operation
Disabled and Enabled
Operation of the automatic reclosing can be set to Off or On via the setting parameters and
through external control. With the setting
Operation
=
Enabled
, the function is activated
while with the setting
Operation
=
Disabled
the function is deactivated. With the setting
Operation
=
External ctrl
, the activation/deactivation is made by input signal pulses, for
example, from a control system.
When the function is set
Enabled
and is operative the output SETON is activated (high).
Other input conditions such as 52a and CBREADY must also be fulfilled. At this point the
automatic recloser is prepared to start the reclosing cycle and the output signal READY
on the STBRREC (79) function block is activated (high).
11.3.6.2
Initiate auto-reclosing and conditions for initiation of a reclosing cycle
The usual way in which to start a reclosing cycle, or sequence, is to start it when a line
protection tripping has occurred, by applying a signal to the PICKUP input.
