Linear Dy5 Transformer
Purpose
Three-phase transformer in Dy5 connection.
Library
3-Phase Transformers
Description
Implements a linear three-phase transformer with two windings in Dy5 connection
using three Linear 2-Winding Transformers. The magnetization inductance
and
the core losses
are modeled as linear elements. Their values are referred to the
primary side.
Parameters and Dialog Box
-
Leakage inductance
- A two-element vector containing the leakage inductance of
the primary side
and the secondary side
. The inductivity is given in
henries (H).
-
Winding resistance
- A two-element vector containing the resistance of the
primary winding
and the secondary winding
, in ohms (
).
-
Winding ratio
- The ratio
between the number of turns of the primary
and secondary winding.
-
Magnetization inductance
- The magnetization inductance
, in henries (H).
The value is referred to the primary side.
-
Core loss resistance
- An equivalent resistance
representing the iron losses in
the transformer core. The value in ohms (
) is referred to the primary side.
-
Initial currents wdg. 1
- A two-element vector containing the initial currents on
the primary side
in amperes (A). The currents are considered positive
if flowing into the transformer. The default is [0 0 0].
-
Initial currents wdg. 2
- A three-element vector containing the initial currents on
the secondary side
in amperes (A). The currents are considered
positive if flowing into the transformer. The default is [0 0 0].
