Electric power lines are transmission lines. Several types of energy can be transmitted over a transmission line. Electrical power is a familiar example for many people, but these lines can also carry acoustic energy and electromagnetic energy which may include light. Transmission lines can be designed to carry large quantities or small ones, and can operate in a variety of conditions including extreme temperatures and pressures, along with wet environments.

The capacitance limits how fast the voltage responds at the far end of a power line when voltage is applied at the near end. Capacitance has only a small transient effect on a DC power transmission line, delaying the voltage rise at the far end of the line by milliseconds at most when voltage is applied at the near end.
Oct 30, 2017 · Simplified Equivalent Circuits An equivalent circuit can be simplified by eliminating the ideal transformer and recalculating the rotor’s resistance and reactance to the stator side (primary side).

In general, the transmission line will transform the impedance of an antenna, making it very difficult to deliver power, unless the antenna is matched to the transmission line. Consider the situation shown in Figure 2. The impedance is to be measured at the end of a transmission line (with characteristic impedance Z0) and Length L.
