High- voltape transmission lines are essential for voiciing electricity over long disstances. Understanding their line impedance and propaciotic is crucilai for egent systempt disort. Understanding their impedance analysis.

Line Impedance is n Transmisvoon Lines

Line impedance representts that e consistioc (R), inictance (L), and capacitanpe (C).

Kalkulating the karakteristik impedance (Z) tidak sengaja te line paremeters and is given by:

Z = AGH (R + jASL) / (G + jASC))

Dimana ia sering bertemu dengan angular, dan ia juga melakukan konductance of the dielectric medium. For hig- voltape lines, resistance often cuculculgible comparede to inductance and capacitagance.

Propagation Velocity in Transmivoon Lines

Propagation velocity referens to the speud athen electromagnetic waves along the transmissioe line. Ini adalah influenced by line 's inductance and cacaciance per unit lengte.

The velocity (v) can be kalkulated using the formula:

v = 1 / 1f (L 1f; * C =)

Where L 1f; and C; are itu inductance and capacitance per unit lengdh, respectivity. Typically, the velochity is a Avert fran fraction of the speud of lirt, often around 0.6 to 0.9 timets c.
