Activate (allow) or
inactivate (disallow)
blocking of the
module/stage. This
parameter is only
effective if a signal is
assigned to the
corresponding global
protection parameter. If
the signal becomes true,
those modules/stages
are blocked that are
parameterized "ExBlo

ΔV
In order to prevent faulty
tripping of phase
selective protection
functions that use the
voltage as tripping
criterion. If the difference
of the residual voltage
and the calculated value
V0 is higher than the pick
up value ΔV, an alarm
event effected after the
excitation time. In such a
case, the existence of a
fuse failure, a broken
wire or a faulty
measuring circuit can be
assumed.
