WebSep 27, 2014 · Armature reaction on a zero leading power factor load Hence at zero p.f. leading, the armature reaction strengthens the main flux. Conclusion For intermediate values of power factor, the effect of armature reaction is partly distorting and partly weakening for inductive loads. WebSome major consequences of low power factor are given below: Larger Load Current – The current flowing across a line is inversely proportional to the power factor for a given power and voltage. Thus, a low power factor will result in a larger load current and, as a result, increased losses.
WebDec 22, 2024 · The effect is called as 'Demagnetising Effect' of armature reaction. Armature Reaction of Alternator at Zero Power Factor Leading : In this case, the current leads the voltage by 90°. so that the coil carries … WebThe direction of the armature reaction flux is opposite to the main field flux. Therefore, it will oppose and weaken the main field flux. It is said to be demagnetized. Armature Reaction at Leading Power Factor If the alternator is loaded with a load of zero power factor leading.
WebMany loads use more power as the voltage increases. Thus, the voltage goes up, causing the power to go up, potentially causing the voltage to go up some more. Many utilities impose a penalty on large customers if they … WebJun 12, 2024 · #2 Better utilisation of conductors. If the pf would have been 0.9, then the normal current would have been 272 amps, but now it is 350 amps. Reason 3 As normal current is now increased, the losses are also increased. Which will further cause more power dissipation.
