Zero-Voltage Point
Consider a single-phase AC power system consisting of two voltage sources (generators) and a transmission line. The complex voltages and impedances are shown in the image.
The source impedances are lumped (concentrated in one place), and the line impedance is uniformly distributed as a function of length (between the buses on either side, shown as vertical line segments).
There is a point on the line at which the voltage magnitude is zero relative to the system neutral. What percentage of the line impedance is between that point and the bus on the left side of the line?
The answer is 70.
