Differential protection for:• Two- and three-winding transformer• Short line (considering the maximum current range)• Bay (for maximal three ends, considering the maximum current

range)

Differential- and full motor protection for:• Motor • amplitudes adaptation, vector groups adaptation, rotating field

adaptation and zero current correction are integrated• 4-section characteristic of biased differential protection• improved sensitivity in the case of earth faults with integrated

biased earth current differential protection (with measuring of neutral point current)

• Overexcitation- and und Inrush restraint (with 2. und 5. harmonics) • Stabilisation against current transformer saturation• Many additionally functions
