Three Winding Transformer - Connection Information

Choose either ANSI or IEC.

Uniquely identifies the equipment item. The program automatically assigns a name, but you can change it, if needed. The name can be up to 30 characters long. Special characters such as &!%^\,? cannot be used in the name.

For three winding transformers, the program automatically assigns the names TW-1, TW-2, TW-3, and so on.

The bus that is connected to the main transformer winding, or the largest MVA winding. This bus must already exist on the one-line. You must be careful that the Primary Bus has approximately the same base kV as the transformer's Primary Rated kV. (However, EasyPower can model any off-nominal kV rating.)  For reference, the Primary Bus base kV is displayed next to the bus name.

Only three-phase buses are available to select. The base kV displays line-to-line (LL) voltage.

The bus that is connected to the secondary transformer winding. This bus must already exist on the one-line. You must be careful that the Secondary Bus has approximately the same base kV as the transformer's Secondary Rated kV. (However, EasyPower can model any off-nominal kV rating.)  For reference, the Secondary Bus base kV is displayed next to the bus name.

Only three-phase buses are available to select. The base kV displays line-to-line (LL) voltage.

The bus that is connected to the tertiary transformer winding. This bus must already exist on the one-line. You must be careful that the Tertiary Bus has approximately the same base kV as the transformer's Tertiary Rated kV. (However, EasyPower can model any off-nominal kV rating.)  For reference, the Tertiary Bus base kV is displayed next to the bus name.

Only three-phase buses are available to select. The base kV displays line-to-line (LL) voltage.
