4. Differential protection

Transformer differential protection T2WPDIF/
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 two or three 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.
