<strong>Volt</strong>/Var Fundamentals‣ Switching capacitors on will reduce the electriccurrent (I) on the line, which will:‣ Reduces the electrical losses (I 2 R)‣ Reduces the amount of energy (kilowatt-hours) required tosupply the existing load and reduces the peak demand on thesystem‣ Indirect control of feeder voltage through CapacitorSwitching which raises the feeder voltage to:‣ Increases the real and reactive load (depending on the kind ofdevice)‣ However, this increases losses in distribution transformers4
<strong>Volt</strong>/Var Fundamentals‣Change in voltage leads to a correspondingchange in power consumption:‣a 1% change in voltage causes a change in kWusually ranging from 0.2% to 1.5%‣Effect of change of voltage on reactive power iseven more significant :‣1% change in voltage causes a change in kvarusually ranging from 2% to 6%The change in load will decay over time, but not to the value before thechange in voltage. The amount and time constant of decay depend on thecharacteristics of the circuit. **KEMA PES Conference June 2005/IEEE Transactions on Power Systems, Vol. 10, No. 2, May 1995; pp. 709-7155
