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« sec.
