Professional Answer: The Ferranti effect is a phenomenon where the receiving-end voltage of a long transmission line can be higher than the sending-end voltage, especially under light load or no-load conditions. This is caused by the line's capacitance, which draws a leading charging current that creates a voltage rise along the line.

This effect is most prominent in long transmission lines because their length and high voltage levels lead to a more pronounced capacitive effect. For our customers working on long-distance projects, this is a critical consideration. To counteract the Ferranti effect, power systems often use equipment like shunt reactors, which are designed to absorb reactive power and help stabilize voltage levels. Our company provides a variety of tools and accessories that support the installation and maintenance of such equipment.
