Protection functions
Description
Operation mode of the function
IED location respect to transformer, HV
(Winding 1) side or LV (Winding 2) side
Connection of the HV side windings
Connection of the LV side windings
Setting the phase shift between HV and
LV with clock number for connection
group compensation (e.g. Dyn11 -> 11)
Local phase current transformer ratio
correction
CT connection type. Determined by the
directions of the connected current
transformers.
Elimination of the zero-sequence current
Selects what restraint modes are in use
