Deif GPC-3 Designers Reference Handbook

Table to read parameter 9141 compared to a step-up transformer:
Vector group Step-up transformer types Parameter 9141
0 Yy0, Dd0, Dz0 0 °
1 Yd1, Dy1, Yz1 30 °
2 Dd2, Dz2 60 °
4 Dd4, Dz4 120 °
5 Yd5, Dy5, Yz5 150 °
6 Yy6, Dd6, Dz6 180 °
7 Yd7, Dy7, Yz7 -150 °
8 Dd8, Dz8 -120 °
10 Dd10, Dz10 -60 °
11 Yd11, Dy11, Yz11 -30 °
DEIF does not take responsibility that the compensation is correct. Before closing the breaker,
DEIF recommends that customers always measure the synchronisation themselves.
If voltage measurement is connected incorrectly, the setting in parameter 9141 will be wrong.
The setting shown in the table above does not include any phase angle twist made by meas-
urement transformers.
The settings shown in the table above are not correct if a step-down transformer is used.
These settings are shown later.
