Voltage Fluctuation definition

Voltage Fluctuation or ‘Voltage Variations’ means series of voltage changes or a cyclic variation of the voltage envelope, the magnitude of which does not normally exceed the specified voltage ranges;

Voltage Fluctuation. , including voltage flicker, means a rapid voltage change in fundamental frequency voltages over several cycles. The rapid voltage changes could also be in the form of cyclic changes (voltage flicker). Note: Voltage Fluctuations are normally caused by start-ups, inrush currents or switching operations of equipment.

Related to Voltage Fluctuation

  • voltage means the root-mean-square value of electrical potential between two conductors.

  • Working voltage means the highest value of an electrical circuit voltage root-mean-square (rms), specified by the manufacturer, which may occur between any conductive parts in open circuit conditions or under normal operating conditions. If the electrical circuit is divided by galvanic isolation, the working voltage is defined for each divided circuit, respectively.

  • Normal Maximum Generation means the highest output level of a generating resource under normal operating conditions.

  • high voltage means the set of nominal voltage levels that are used in power systems for bulk transmission of electricity in the range of 44kV<Un 220 kV. [ SANS 1019];

  • low voltage means the set of nominal voltage levels that are used for the distribution of electricity and whose upper limit is generally accepted to be an a.c. voltage of 1000V ( or a d.c. voltage of 1500 V). [SANS 1019]
