What is the term used when an open-ended transmission line experiences high voltage due to its inductance?

The correct term for the phenomenon where an open-ended transmission line experiences high voltage due to its inductance is known as the Ferranti Voltage Rise Effect. This effect typically occurs in long transmission lines, especially when they are lightly loaded or open-circuited at the ends.

In such cases, the reactive power generated by the line's capacitance can cause an increase in the voltage at the receiving end beyond the sending end voltage. This results from the inductive nature of the line, where the inductance leads to a delay in the current flow, resulting in a higher voltage being observed at the terminal point.

Understanding this concept is important in electric power systems, particularly during the design and operation of transmission lines, as it can influence voltage regulation and the overall stability of the network. Proper management of the Ferranti effect is crucial to ensure that voltage levels remain stable and do not exceed operational limits, which could lead to equipment damage or failures.

The other terms refer to different phenomena. For example, the skin effect relates to the tendency of alternating current to distribute itself within a conductor, while surge impedance loading refers to the maximum power transfer capability of a transmission line at a specific loading condition. Transformer saturation deals with the limitations of transformers when subjected to
