What is reactive power — and why does it matter? - Medium

WebReactive compensation in a transmission line is essential, as the reactive power generated is greater than that which is absorbed. Passive Compensation Shunt reactors and series capacitors can reduce the voltage rise if placed at suitable locations in the transmission line. WebReactive power, or VAr, is not really power at all but represents the product of volts and amperes that are out-of-phase with each other. Reactive power is the portion of electricity … Webeffect, the reactive power versus voltage characteristic should be specified separately from the reactive range. For example, in addition to a “0.95 lead to lag” reactive range requirement, the chart shown in Figure 2 could be used to specify the reactive power capability versus voltage characteristic.
