voltage regulation

[′vōl·tij ‚reg·yə‚lā·shən]
(electricity)
The ratio of the difference between no-load and full-load output voltage of a device to the full-load output voltage, expressed as a percentage.

Voltage Regulation

 

(in power distribution networks), measures taken to maintain electric voltage within specified limits. In modern systems, all processes of voltage regulation in cases of changes in load (or the occurrence of breakdown conditions, such as a short circuit, in individual sections of the network) are performed automatically by special devices, mainly devices for automatic regulation of excitation in electric generators and synchronous compensators.

Voltage regulation

The change in voltage magnitude that occurs when the load (at a specified power factor) is reduced from the rated or nominal value to zero, with no intentional manual readjustment of any voltage control, expressed in percent of nominal full-load voltage. Voltage regulation is a convenient measure of the sensitivity of a device to changes in loading. See Generator, Transformer
