ABB Relion 670 series - Identification

Considering the safety margins mentioned previously, the minimum setting (Is) is:
I

= 1.3 × I
min
EQUATION288 V3 EN (Equation 458)
The IED setting value IN>> is given in percent of the primary base current value, IBase.
The value for IN>> is given by the formula:
( ) 100

IECEQUATION17003 V1 EN (Equation 459)
Transformer inrush current shall be considered.
The setting of the protection is set as a percentage of the base current (IBase).
Operation: set the protection to Enabled or Disabled.
Pickup: Set operate current in % of IB.
IN>>Max and IN>>Min should only be changed if remote setting of operation current
level, IN>>, is used. The limits are used for decreasing the used range of the IN>> setting.
If IN>> is set outside IN>>Max and IN>>Min, the closest of the limits to IN>> is used
by the function. If IN>>Max is smaller than IN>>Min, the limits are swapped.
MultPU: The set operate current can be changed by activation of the binary input
MULTPU to the set factor MultPU.
