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

Threshold
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.
Only available if: Device Planning: 51Q.Mode = 46
0.01 - 4.00In
0.1In
[Protection Para

%(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). Phase
sequence will be taken into account automatically.
Only available if: %(I2/I1) = Use
2 - 40%
46[1]: 40%
46[2]: 20%
