3. Differential protection
Transformer differential protection T2WPDIF/T3WPDIF
The Transformer differential protection, two-winding T2WPDIF
and Transformer differential protection, three-winding
T3WPDIF are provided with internal CT ratio matching, vector
group compensation and settable zero sequence current
elimination.
The function can be provided with up to six three-phase sets of
current inputs. All current inputs are provided with percentage
bias restraint features, making the IED suitable for two- or
three-winding transformer in multi-breaker station
arrangements.
