Primary Side of a Two-winding Transformer
>>Basics>Circuit>Transformers>Single-Phase Systems
The component represents a transformer based on the Spiro model. The use of this macro
makes only sense with at least one macro of the secondary side. Using the Primary Side and
Secondary Side of a Two-winding-Transformer allows a simple construction of a Single-Phase
Transformer with more windings.
The terms primary and secondary are not to understand in the strict sense. It means only to
combine exactly one macro of the primary side with at least one macro of the secondary side.
For each coil make sure a network path exists to the ground node. The macro does not provide
an access to the initial value of currents, these are assumed to be zero. Within the dialog you
can define the leakage inductances, the equivalent resistances for iron losses and the winding
resistances for the primary side.
