How do you control reactive power?

The reactive power depends on the load and not the generator. Reactive power can be detected at the generator, and the load disconnected if there is too much being drawn. A generators's voltage depends on the speed, and the power produced depends on the current in the field winding. An alternator running on a bus bar, as in a grid system, runs synchronously with the grid it is connected to. In this case the power produced depends on the rate that steam is supplied to the turbine, and although the speed stays constant, any increase in power output is accompanied by an advance in the phase angle of the rotor.


What is reactive power compensation?

Reactive power compensation involves adding capacitors or inductors to electrical systems to improve power factor and reduce reactive power consumption. This helps optimize energy efficiency, reduce losses, and enhance overall system performance.


Why the value of power factor should be low?

no.... the power factor of any machine should be as near as to 1 when the power factor becomes near to 1 there is no need to the alternator to supply the reactive power.. but in general all most all the loads in the power system inductive in nature the power factor is becoming lagging(<1) so to avoid this the power generating companies and the govt. are recommending the people to have the capacitors at the load ends....... since the capacitive reactance can nullify the effect of the inductive reactance this will try to improve the power factor


Is aluminium a most reactive metal?

Aluminum is pretty reactive, but it is nowhere near the most reactive.


What is the air fuel ratio in a diesel cycle?

32A diesel engine has no throttle plate so it always takes in maximum amount of air and the fuel injected is varied according to load, rpm. It ranges from 50:1 or leaner at idle to stoichiometric ratio (dont think its the same as petrols) at full load. It can vary from near 100:1 at no load to under 15:1 at full load.


Power factor correction capacitors?

Yes, they exist. Capacitors are often used to change a low power factor (such as 0.5) to a higher power factor near unity (1). In some instances, this will lower fees and costs to utilities. In homes, this is not really necessary as most devices used in homes are near unity power factor, or tend to be minor/sporadic loads (such as a washing machine).


Does a capacitor reduce electricity?

Absolutely not, if you are a residential consumer. Capacitors, when used for power-factor correction, reduce the supply current but NOT the amount of energy consumed and you pay for energy, NOT current! Energy meters measure the supply voltage and the in-phase (resistive) component of the supply current, so power-factor correction is irrelevant to residential metering. The video referred to in the original answer shows current being reduced but, as explained, this has absolutely no relevance to your electricity bill. In fact, the video is complete and utter nonsense! Capacitors used in this way are a complete scam.Power-factor correct ONLY applies to large commercial and industrial consumers because they are penalised for unnecessarily-low power factors because the resulting unnecessarily-high currents require the utility companies to install larger transformers, switchgear, and cables.Another AnswerYes, if you are a big customer and you are paying a premium on your power charges through having a poor power factor on the site. Otherwise a capacitor does not reduce the kWh consumption of your appliances, but it might reduce the current you draw, but your meter measures energy used and not the current. For a domestic customer power factor correction will almost certainly notreduce your charges.


What is an automatic power factor control panel?

somewhere near where power comes into a building there is a phase angle or power factor meter automatic control will add capacitor banks until the phase angle is 0 when fluorescent lamps used transformer ballasts there could be lagging power factor lightly loaded motors do this too the power company charges you more if you have a load that is not near unity


How many decibels is it when an airplane is taking off?

Depends on the aircraft , the load it is carrying and the weather ........... A jet plane may not alway use full power on takeoff.........if it is a hot day , a runway at a high altitude , or a heavy load on board then it may use full power ......... If you are near the runway and it is painful to hear , it is probably over 95 decibels ....


What is the purpose of a zener diode when placed near the output in a common power suplly?

The purpose of a zener diode connected at the output of a common supply is to stabilize the output voltage in case a load is connected to it.


Where is the pcv valve located on a 1989 ford mustang lx 2 3L 4-cyl fuel injected automatic?

it is near the distributor, there is a black hose located near towards the rear of the car near the distributor.


What rating of capacitor may use to improve power factor?

This will depend on your load. If your load has a total VAR requirement of 200k, then you should look at capacitors that will supply near that amount of VARs. Note the actual capacitance will differ depending on the voltage you're connecting to. Also you don't want to purchase too much, which will just push your power factor in the opposite direction too far. You need to look at your load profile, and size for minimal load, confirm this keeps maximum load within your desired pf, and if it doesn't you'll have to add some automated switching of the caps.
