Control of the
Internal Automatic
Reclosure by an
External Protection
Device
If the 7SA6 is equipped with the internal automatic reclosure function, it may also be
controlled by an external protection device. This is of use for example on line ends with
redundant protection or additional back-up protection when the second protection is
used for the same line end and has to work with the automatic reclosure function
integrated in the 7SA6.
