- Steps 4–f, 4–g and 4–h can also be done phase wise.
* - UBase is considered as 400 kV and VT ratio as 400 kV/110 V
The voltage inputs U
L1
, U
L2
, and U
L3
refer to the bus voltages and U
TapL1
refers to the tap voltage of
phase L1.
** - This step should be done only during Factory Acceptance Test (FAT). At field, the testing should be
done with the stored field values.
To calculate PUDIFL1 in steps 4-f, 4-g and 4-h, use the following equations:
