The protection algorithm is prepared for applications where a transformer is included in the protection zone, in which case special measures are taken such as inrush restraint or vector group compensation.
The Line Differential is prepared to selectively detect high impedance internal faults while offering high immunity against external faults with CT saturation.
Two independent current differential stages are available: one unrestrained stage for fast tripping of low impedance faults and one restrained stage more sensitive to faults with low differential currents.
