Definition: The word "arcature" refers to a device that rotates around a central axis, typically in a vertical direction. It's an electrical component used in power systems for voltage regulation and control purposes, especially in electric transformers and transmission lines. Arcature is typically made up of a series of poles connected in parallel, with each pole serving as a primary circuit element (also known as the primary). The key feature of an arcature is its ability to regulate or regulate voltage across it, allowing for efficient power distribution within the system.
