Electrical Engineering ⇒ Topic : T-section
A network is said to be T-section when it looks like a T. The asymmetrical and symmetrical T-sections are shown in Figure 1 (a) and Figure 2 (b), respectively.
In an asymmetrical T-section, the total series impedance is Z1 + Z3 whereas in symmetrical T-section the total series impedance is 2Z1. The shunt impedance in both the cases is Z2.
Figure (1) T-section.
Figure 2 (a) and Figure 2 (b) show the unbalanced and balanced T-section, respectively of symmetrical configuration. The unbalanced and balanced asymmetrical configurations can also be shown in the same way. The balanced T-section is also called as H-section.
Figure (2) Symmetrical configuration of T-section.
