The following table provides the phase shift in degree lag based on the selected transformer type.
Format
16-bit unsigned integer
Range
0 to 359
Unit
Degrees
Default
330 (Dy-11)
For example, if the transformer type selected is Dy-11, select the transformer angle as 330°. That is, the LV
system lags by 330° with respect to the MV system.
