Application Example
During a “Switch-OnTo-Fault” condition, the User is usually requested to make the embedded protective function
tripping of the faulted line faster, instantaneous, or sometimes non-directional.
Such a “Switch-OnTo-Fault” application can easily be realized using the
Adaptive Parameter
features mentioned
previously. The standard time overcurrent protection element (e.g.: 51P) should trip instantaneously in case of
SOTF
condition,. If the
SOTF
logic function »SOTF ENABLED« is detecting a manual breaker close condition, the relay switches
to
Adaptive Set 1
if the signal »SOTF.ENABLED« is assigned to
Adaptive Set 1
. The corresponding
Adaptive Set 1
will
become active and than »
t = 0«
