A poor power factor is caused by inductive loads or electronic devices. These loads cause excess current to flow in the circuit reducing the efficiency. Inductive devices are considered to be a "load" for reactive power. Reactive power does not actually do any real work by is required to develop magnetic fields. Capacitors are considered to be "sources" of reactive power. So these capacitors will supply the reactive power to the inductive loads instead of the utility supplying this power. This is why capacitors are used to improve a poor or low power factor. This is just a very brief description on this topic. Power factor correction is becoming a very complex topic with more and more poor power factor loads being used every day.

Can the capacitor be inserted in series in order to improve the power factor?
In a circut we use capacitor in series for improving power factor
Why does a capacitor improve power factor?
yes power capacitar ust inprove the power factor and sae the kvah reding
What is the technique of improve the power factor?
Simple technique by adding PP capacitor with automatic power factor controller.
Advantages of bank capacitor?
Capacitor banks can improve the power factor if the load is leading, which is unusual. Typically in substations capacitor banks are employed to reduce over voltage.
Why you install capacitor bank in electrical room?
Capacitor banks are installed in the electrical room to improve the power factor which is related to the inductive load caused by motors etc . The capacitors create a capacitive load which subtracts against the inductive load thereby improving the power factor. Most power utilities have penalties when your power factor drops below a certain value.
Can capacitor increase low voltage to high voltage?
yes a capacitor can improve voltage by improving power factor
What are the advantage of automatic power factor control?
It automatically controls the power factor with respect to the set point defined, by putting on or off the capacitor banks as needed.
Control diagrame of a capacitor bank and why you use capacitor banks?
---- Capacitor banks used to improve power factor(lagging) of a circuit:: This is necessary since it causes saving in power and electricity bill in following ways: 1) As p.f rises, circuit currnt decreases and hence I2R losses reduce 2) Var consumption reduces There is no tool provided here to draw the ckt diagram:: U take on PFC(power factor correction bus), then connect switch fuse, then HRC fuse, then Contactor, then overload relay and finally the capacitor bank
Causes of low power factor methods of improving power factor?
using highly inductive loads may lead to reduction in the power factor. or consumption of unappreciable amount of power also results in the same. methods to improve PF . using synchronous condensers using capacitor banks using ow inductive loads
What method improve power factor?
The most common method of improving the power factor of a load is to connected a capacitor or capacitor bank, of appropriate reactive power (expressed in reactive volt amperes), in parallel with the load.
What effect a capacitor has on a supply current on an inductive load?
it will improve the power factor... The angle between voltage and current will decrease depends on capacitor value.
What will be the PF if measured after capacitor bank?
Capacitors are used to improve an inductive load's power factor towards unity. The power factor before and after adding the capacitor bank depends entirely on the inductive/capacitive values involved.
