'voltage variation' is a correct phrase that is used in written English.
For example, you could use the phrase in the sentence "The circuit had an irregular voltage variation that disrupted its performance."
In experiments 2 9, the terminal conditions were chosen according to the analysis of the overall voltage variation during overdischarge (Fig. 1(c)).
Experiments 12 16 were performed to investigate the overall voltage variation of the battery during overdischarge, and a typical voltage curve was drawn (Fig. 1(a)).
The effect of current density on purge frequency and voltage variation is shown.
However, the power capability is easily affected by dynamic load, voltage variation and temperature.
Among these, voltage variation is of particular concern and needs to be addressed concisely.
Thus, the voltage variation due to added particle, can be used to identify the particle's mass.
The predicted battery surface temperature distribution and voltage profile are in agreement with infrared imaging and the measured voltage variation.
If it is installed in large quantities, voltage variation occurs with a risk of worsening electric power quality.
The main purpose of this paper is to investigate the major factors that affect the voltage variation on distribution feeders.
Further, the voltage variation and reactive power compensation is analysed with the incorporation of proposed ANFIS based UPFC controller.
The reliability figures were >94% for temperature variation (0 85 °C) and ±5% of core voltage variation.
