The change in output voltage that occurs when the load (at a specified power factor) is reduced from rated value to zero, with the primary impressed terminal voltage maintained constant.
A measure of how well a rectifier battery plant can control the steady state DC output voltage under two extreme conditions: (1) Vo at no load current with the input AC voltage at the designed maximum value, called Vomax; (2) Vo at full load current with the input AC voltage at the designed minimum value, called Vomin. %Regulation = ((Vomax - Vomin) /(Vomax + Vomin)) x 100 Note: "±" is used to distinguish the above regulation formula from the classical equipment formula defined as: %Regulation = ((Vonl -Vofl) / Vofl) x 100 where fl = full load, nl = no load and Vin is kept at rated value.
A measure of the ability of a generator or power supply to maintain a constant output voltage from no-load to full-load operation. Expressed as a percentage of full-load voltage; the better the regulation, the lower the percent.
a process to maintain the terminal voltage within required limits despite variations in input voltage or load
This indicates the variability in the output voltage. Better units will produce a nearly constant root-mean-square (RMS) output voltage for a wide range of loads.
Control of voltage within prescribed limits. Under Std 1547, a Distributive Resource is not to attempt to regulate voltage at the point of common coupling nor to cause the voltage on other parts of the EPS to exceed standard limits.
A means of maintaining the equipment voltage at a constant level. Domestic AC power is distributed at a nominal 120V but this can vary depending on the load and other factors in the distribution. A voltage regulator adjusts for those variations to provide a constant 120V at the equipment.
Voltage regulation is a measure that states the difference between maximum and minimum steady-state voltage as a percentage of nominal voltage.
For a transformer, the change in secondary voltage which occurs when the load is reduced from rated value to zero, with the values of all other quantities remaining unchanged. The regulation may be expressed in percent (or per unit) on the basis of the rated secondary voltage at full load.
The change, in percentages, of the output voltage from no load to full load.
The process of maintaining an essentially constant output voltage over variations in input voltage or load.
In electrical engineering, particularly power engineering, voltage regulation is the ability of a system to provide near constant voltage over a wide range of load conditions.
