Protective Elements
Parameter Description Setting range Default Menu path
ExBlo Fc 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 Fc=active".

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).
Phase sequence will be taken into account
automatically.
