如何向该传输线模型添加变压器？

我希望有知识渊博的circuitikz大师能帮我解决这个问题。我需要添加一个变压器Vl，但恐怕我不知道它实际上是如何工作的。任何帮助都非常感谢。

Transmission line model

\begin{circuitikz}[scale=1.0]
   \draw
          (0,0) to [short, o-] (1,0)
          (6,0) to [short, o-] (0,0)
          (6,0) to [open, v_<=$V_{m}$] (6,2) % load voltage
          (5,2) to [short, l=$P_{ml}+jQ_{ml}$, -o] (6,2) % load power

          (0,0) to [open, v^<=$V_{l}$] (0,2) % generator voltage
          (0,2) to [short, o-, l^=$P_{lm}+jQ_{lm}$] (1,2) % generator power
          (1,2) to [C, l^=$j\frac{b_{sh,lm}}{2}$] (1,0) % shunt susceptance
          (1,2) to [R, l=$R_{lm}$] (3,2) % line resistance
          (3,2) to [L, l=$jX_{lm}$] (5,2) % line reactance
          (5,2) to [C, l_=$j\frac{b_{sh,lm}}{2}$] (5,0); % shunt susceptance
\end{circuitikz}

像这样？

MWE 中的所有坐标均对应于变压器的坐标......

\documentclass[border=3mm]{standalone}
\usepackage{circuitikz}

\begin{document}
    \begin{circuitikz}[scale=1.0]
% transformer
\node[transformer,left=5mm] (T) {};
\draw   
    (T.A1)  to [short, -o] ++ (-0.5,0)
    (T.A2)  to [short, -o] ++ (-0.5,0)
    (T.B1)  to [short, -o] ++ (0.5,0)       coordinate (in+)
    (T.B2)  to [short, -o] ++ (0.5,0)       coordinate (in-)
    (in+)   to [open, v<=$V_{l}$] (in-)                                     % generator voltage
    (in+)   to [short,  l^=$P_{lm}+jQ_{lm}$] ++ (1.5,0)     coordinate (c1+)% generator power
            to [short,C,l_=$j\frac{b_{sh,lm}}{2}$] (c1+ |- in-)             % shunt susceptance
    (c1+)   to [R, l=$R_{lm}$]  ++ (1.5,0) % line resistance
            to [L, l=$jX_{lm}$] ++ (1.5,0) coordinate (c2+)                 % line reactance
            to [short, l=$P_{ml}+jQ_{ml}$, -o] ++ (1.5,0)   coordinate (out+)
%
            to [open, v^<=$V_{m}$] (out+ |- in-)            coordinate (out-)% load voltage
    (c2+)   to [C, l_=$j\frac{b_{sh,lm}}{2}$] (c2+ |- in-)   % shunt susceptance
%
    (out-)  to [short,o-] (in-); % shunt susceptance
    \end{circuitikz}
