In an ungrounded system, what is the return path for the capacitive coupling between the high voltage line and the earth to maintain the flow?
In an ungrounded (or isolated grounding) power system, there indeed exists capacitive coupling between high-voltage lines and the earth, forming a capacitive current path. This phenomenon occurs because the electric field between the high-voltage conductors and their surrounding environment, including the ground, causes uneven charge distribution, resulting in what is known as "earth capacitance."Return Path Through Capacitive Coupling Earth Capacitance: Each high-voltage line has a certain amou
