A video is worth a thousand words. excellent this really helped

[LEDesigngroup]

@erdnallewen glad we could assist - thank you for checking out the video!

good day guys, i was wondering if i can install such capacitors to household appliances with motors like refrigerators or ACUs, thanks guys! more power!

[LEDesigngroup]

@Lionelmanalaysay - it is possible although not common. Any electric motor can have a capacitor attached in parallel to capture the reactive current of the windings. Caution should be used however to insure that the capacitor is sized properly for the load it is expected to carry. thanks!

Im doing a degree in electrical engineering and renewable energy and one module we cover is sustainabilitty and business management, its alot of power factor correction, this demonstration seems to make perfect sense and is doing just what it should. sweeeeet !!

[LEDesigngroup]

sounds like an interesting program - best of luck and thank you for your input!

PLZ correct me iam worng .active power is the power deliverd to a motor which runs the motor.reactive power is the power produced by megnatic field of motor which oppose the orginal power and cause lagging of current form voltage.iam worng or right PLZ reply and correct the active and reactve power

@LEDesigngroup how may capaciter you used and if capcaitors are more than one than tell me how capaciters are connected to each other and also tell me about capacitor rating

[bartallen69]

@salvadoreec the value of cap depends on the value of inductance and the frequency that the two will see and the maxi voltage of the system. The formula for computing these values are based upon Tank circuits. Also, an inductor will attempt steady current for as long as possible through it, and will raise its own voltage to any value necessary to accomplish this end. Cap voltage rating is very important. I mostly suggest read/talking to as many people as possible, caps can give a lethal shock.

[salvadoreec]

What are the characteristics of the capacitor? Is it a current, resistance, formula to get the capacitor value in Farads? Thanks!

The question is can home users benefit from PF correction. The obvious answer is NO because their consumer power meter does not monitor PF.

Typical reactive power is inductive causing the current to lag voltage and the power is not efficient. Correcting PF should cause VA to be in phase (or closer to unity), and the power is more efficient. I wonder if since both V and I amplitudes are less when PF corrected if the consumer benefits any from less ac current.

That will be my next experiment!

@TruthQuest111

I agree and stopped using CFLs for our off grid applications because the CFL has a horrible PF. The utility meter in industrial commercial account monitors and bills customers more per kWhr when the PF falls below a certain level. Industry works to correct PF, and the utility grids works to switch capacitance in line in real time for efficiency in the distribution grid.

The home user is only billed for watts, not VA.

I personally do not like CFLs, even when PF corrected.

[TruthQuest111]

With all respect to your careful effort in trying to save us money I have an electrical engineering degree and have scoured the internet on whether the consumer is actually being charged for apparent power. Overwhelmingly every source that I've consulted indicates that we are charged only for resistive loads - not the inductive component. If what your saying is true then we might as well not use cfl bulbs since they also cause substantial phase losses..

In domestic applications, this could help reduce electrical consumption?, Greetings

@SidneyBou I noticed this too
