What is the use of synchronous machines in power grid system?
To improve the power factor
Why inductor is used in electrical circuit?
To improve the power factor
Is it advisable to correct the power factor to unity?
power factor depends on the load being fed if the load is entirely resistive power factor will be unity ..if the load includes an inductor or capacitpr due to phase displacement between v and i the pf will be lag or lead respectievly
How you improve power factor in synchronous motor?
Power Factor measures the difference in phase between the current and voltage. When they are in phase the Power Factor is defined as 1. When out of phase the value is less than 1. If they are 180 degrees out of phase the Power Factor will be zero.
What is the function of a capacitor in a fluorescent light fitting?
A capacitor is used to improve the power factor of the lamp.More detailsTo prevent the lamp from taking too much current a fluorescent lamp has to have a choke, which has magnetic inductance. The inductance has a negative impact on the power factor of the (the ratio between apparent power and real power taken by the lamp) - i.e. the power factor is reduced - so a capacitor is used to compensate for the inductance by improving the power factor so that it is closer to the ideal value of 1.Basically the inductor with the capacitor smooths out the voltage or current.
What is a method to improve the power factor?
Add capacitors from line to ground.
How power factor helps to improve circuit?
Improving power factor does nothing to improve a circuit. It merely affects the amount of current drawn by the load.
Why the power factor improves with the load?
Power factor doesn't necessarily 'improve with the load', but it is determined by the load.
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.
What is the use of synchronous machines in power grid system?
To improve the power factor
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 inductor is used in electrical circuit?
To improve the power factor
How can improve the power factor?
To increase capacitive load and decrease inductive loadAnswerThe most common method is to add a capacitor, or a capacitor bank, in parallel with the load. In practise, the reactive power of the capacitor (they are not rated in farads, but in reactive volt amperes) must be a little short of being equal to the reactive power of the load, so that the power factor approaches, but does not equal, unity.
Can we improve generator power factor for increasing active power?
The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.
How select the rating of capacitor with respect to KW for improving power factor?
The capacitors must be sized according to the reactive power being used, not the real power being used, to improve power factor.
What equipment used in power factor improvement?
The simplest method of power-factor improvement is by using appropriate capacitors, connected in parallel with the load. Power-factor improvement capacitors are rated in reactive volt amperes, not farads.
