I've found the de (distance relative distance) and xl using the formula (u/2pi)*ln(de/gmr) and converted the unit. If a load equal to the characteristic impedance is placed at the output end of any length of line, the same impedance will appear at the input terminals of the line. The transmission line has a characteristic impedance, but this might not be the actual impedance you’ll measure in a real experiment. The question ask to solve for the impedance of a 3ph transmission line. The characteristic impedance is determined by z 0 = √ z lz h. The characteristic impedance determines the amount of current that can flow when a given voltage is applied to. Where r0 and x0 are the real and imaginary parts, respectively. It is probably not much more than a mathematical exercise, but you never know when it might be useful. The characteristic impedance \(z_\text{c}\) of a length \(\ell\) of transmission line can be derived from measuring its input impedance \(z_\text{in}\) once with the transmission line terminated in a short and a second time left open. The reason for this approach is due to the behavior of real electrical signals on a transmission line.
L and c are related to the velocity factor by: Characteristic impedance is a key factor for impedance matching, either for emc\emi consideration or maximum power delivery to the receiver. I've found the de (distance relative distance) and xl using the formula (u/2pi)*ln(de/gmr) and converted the unit. = z l −z 0 z l +z 0 (c.1) the expression for the input impedance z i has many forms. It is probably not much more than a mathematical exercise, but you never know when it might be useful. The characteristic impedance is the only value of impedance for any given type and size of line that acts in this way. The impedance will be equal (in general case) to a relation between maximums of tangential components of e and h fields along any line in z. Obviously, prior to connecting the transmission line, the vna is calibrated at its device under test (dut) port with a short, open and 50 ω load. If you are looking to transfer all the incident energy on a transmission line to the load end, terminate. The input impedance is simply the line impedance seen at the beginning (z=−a) of the transmission line, i.e.: When you have found the line impedance, you can measure the propagation velocity with sinewaves.
