Voltage provided by regulators is changed using a tap-changing switch to adjust the number of secondary windings. Bypass switches allow a regulator to be removed for normal service without interrupting the downstream load.\nNOTE Subtypes include: Single Phase Overhead, Two Phase Overhead, Three Phase Overhead, Three Phase Pad-Mounted.
