ExBlo Fc
Activate (allow) or

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
parametrized "ExBlo

I2>
The Threshold setting
defines a minimum
operating current
magnitude of I2 for the 46
function to operate, which
ensures that the relay
has a solid basis for
initiating a current
unbalance trip. This is a
supervisory function and
not a trip level.

%(I2/I1)
The %(I2/I1) setting is the
unbalance trip pickup
setting. It is defined by
the ratio of negative
sequence current to
positive sequence current
(% Unbalance=I2/I1), or
%(I2/I1) for ABC rotation
and %(I1/I2) for ACB
rotation.
