The impedance looking into a matched line
WebTuning stubs are segments of open-ended or short-ended transmission lines that are used for distributed impedance matching. Both open and short stubs can be used for impedance matching. From the transmission line theory, we know that open and short stubs have a pure imaginary input impedance. WebThe impedance of a transmission line with a length of 50 km is given as z = 0.08 + j0.48 22/km. At the end of the line, a power of 250 MW is drawn with a lagging power factor of cosy = 0.95 under 220 kV voltage. Under these conditions, find the voltage, current, and power factor at the beginning of the line. Problem 2.26P: A small manufacturing ...
