Transformers
The transformers to be used in design are defined in this section. You can enter transformer sizes for various voltage levels.
| Option | Description |
|---|---|
|
kV |
The primary and secondary kV of transformers are displayed in the list. To add any new kV level not in the list, click Add New and enter the primary and secondary voltages for the transformers. To delete any voltage level, delete all the spreadsheet entries for the level. |
|
Base kVA |
Transformer self cooled rating in kVA. |
|
Z% |
Percent impedance of transformer. |
|
Type |
Insulation/cooling medium, such as oil, gas, dry, and so on. |
|
Class |
Cooling class designation. |
|
Temp |
ANSI temperature rating of the transformer. Various combinations can be selected and are dependent upon the type of transformer. Dual ratings such as 55/65 increase the overload capability of the transformer by 12 percent. |
|
Cooled Rating (kVA) |
Forced cooled rating /overload rating in kVA. |
|
Pri FLA |
Primary full load amps. |
|
Pri Brkr/Fuse Amps |
Amp value used for selecting primary side protective device. |
|
Sec FLA |
Secondary full load amps. |
|
Sec Brkr/Fuse Amps |
Amp value used for selecting secondary side protective device. |
