3. Differential protection

Transformer differential protection T3WPDIF
The Transformer differential protection is 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 if enough HW is available. 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.
