Too complicated here in Africa we just bypass the meater and don't pay

Simple and straightforward explaination...but with a p.f. corrected cap in circuit your household wiring draws lower utility current...so it's that much lesser stressed... Now the properly rated hardware...( wire gauge..fuse ratings...thermal trips...ckt.brakers...switches & sockets... etc ..) can be optimally downsized..so this lowers the costs....& improves the overall " safety factor" of your household equipment..so you become a contributor to improving the " electricity footprint " in s small way.

Such an informative video. Wonderful explanation in a simple way

What is the advantage of opperate a sircut with leading power factor?

The energy loss in the wires are reduced with capacitor installed. That's how it will save energy. So capacitor definitely helps

With a proper circuit board like ras pi you could hook up a capacitor for the start load, batteries for saving power, and set a charge time in your computer for the cheapest time of night. If you have solar, you can charge in daytime too. Test your home power usage before buying equipment or trying to salvage old equipment.

Hi, How about capasitor in dc ceiling fan? Is it consuming electricity even you off the fan switch?

Very good sir...adding capacitor will not save power

a capacitor is can only improve pf not KW/H reduce

informative video tnX thou with lower total Amp need smaller gage cable so it helping but not the way ppl think thou

Very good and informative.Keep it up.

Its informative video. My question is , doesnt it depend on where we installed capaciotrs. If we install capacitor on HT side only to improve power factor but LT side equipment working inefficiently, so by improving PF at end , ultimately being converted to high units

Note that in the USA, while most home circuits are 110-120VAC, the input into the house is 220-240VAC and then split into two 110-120VAC legs. So if the house's wiring relies on only one of the two 110-120 VAC legs, you get charged as if you used both, doubling your bill. So it is generally best to make sure that the appliances that use the most current over each day are evenly split between the two different 110-120VAC legs.

Attention between KW, KVA, KVAR, KVD (distorsion wave). KVA=KW+KVAR+KVD. The metter measures only KWH, means active power, means power like in DC current, U*I=P (watt). The metter doesn't know about KVAR, KVA, KVD. For this exist special metters. The cos xx si for metter ideal, means 1. For this the metter is built to measure correctly the power for what we pay the bill. The rest is theory for us. A capacitor consumes nothing in ac/dc circuit, the resistance, capacitance is big. The voltage is danger for it.

I don't know yet about the other, but some of the metering device used in houses calculate the power consumed by only reading the current without the voltage and power factor. They just use magnetic induction caused by the pasing current and show the kwh consumed

Great video sir. Thank you for your clear explanation.

In your example, 2 variables have changed. Before capacity installed, PF=0.6 & current = 36A. After capacity installed, PF=0.8 & current = 27A. Why is there a change assuming all other factors remained the same. Should current also stays at 36A?

Thank you for clearing doubts

Hai dear I dought single phase load on 1 kWh depending which number mfd capacitor putting low cosuption power repaly msg

P=i²r If current decreases the power also decreasing R resistant is constant

your explanation is good, but you need to mention the extra cupper power loss I^2 R withen the cables which can be reduced if we improve the power factor.

How to install the capacitor?

Good morning sir,thank you for yours explanations, loud and clear, from your side how to reduce bill?

Thanks a lot to describe actual scientific logic.

In generator terms I'm not sure exactly what bad power factor is doing. Resistive loads provide constant slowing in the generator, but reactive loads are slowing the generator for part of the cycle and speeding it up for the other part - like putting a spring on an arm on the generator? Also they waste more energy in wires because you have higher peak currents than you need with a purely resistive load. It's like trying to start a car engine which is a combination of mechanical resistive and reactive loads. It has a flywheel which is inertia to accelerate (inductive) and compression in the cylinders (capacitive) and finally air resistance in the valves and exhaust and oil resistance and friction in the cylinders and coolant flow (resistive). Or if you take a fixed gear spin bike with a big steel flywheel from a gym, the inertia to pedal up the generator in the flywheel is inductive reactance that will kick your feet if you lock your legs from high speed. The felt pads on the flywheel are a resistive load. A capacitive load would be attaching a spring to the flywheel that stretches and actually prevents the pedals turning after a certain amount of stretch, so only if you pedal forwards and backwards will it work.

Well explained I hope all layman realize how they get fooled by such devices.

What is the best option to safe electricity ?

Capacitor are use to control apprant current and recative current

Those so-called "electric saver" devices are actually a capacitor used to "dampen" the inductive effect of electrical devices with coils such as old flourescent lights or old aircond compressor on the electrical wiring's total resistance (inductance contributes to resistance in AC circuits). If the inductive effect is either small or absent due to usage of energy-saving electrical devices or flourescent lamps being replaced with LED counterparts, then the capacitor itself will contribute to the total resistance of the wiring via capacitive effect. Total resistance R (total) = R + √(xL^2 - xC^2)

If the voltage drop across the cable is large, does the change in power factor not cause the voltage drop in the conductors to decrease? The power loss on the conductor would decrease and the wasted power would be less. Maybe the calculation of economic efficiency should be more complex.

I'm your new subscriber frm the Philippines. You are ok! Your explanation is clear. The only thing unclear is the value of the capacitor, where to connect it & how to connect it. I consume 250 KW every month. Now, forgetting all other videos and or explanations, let's go straight to the point. Would a 5 - 10 uF/450v rated capacitor used in washing machines & air conditioners achieve the purpose? Which one along that range is the best? Also, I constructed below a table (if you will), where, as I said, being straight to the point, you can fill up, based on your computations, the capacitor ratings in accordance to monthly consumptions. KW USED CAP VALUE 400KW. ____uF This, based on the assumption that the capacitor is wired in the main panel thru a circuit breaker or a fuse. Thanks in advance for the answer.

True why can't make mandatory by bescom national savings.

I connected two 2.2mfd capacitor in parallel very near to the main switch(that is near to the meter). Now Iam getting electricity bill continuously 25% less than before how?

yes for the surge...not for running amp..

Now I understand the whole concept

what capacitor do I use for power factor?

Only large usage of KW/electricity that have inductive loads will benefit from capacitive power factor correction. It's better to focus on the efficiency of specific devices by factoring in lumens/watts or horsepowere/watts.

I doubt the average home would have enough induction motors to affect the PF very much, I worked in mining for many years, I served my apprenticeship as a coal mine electrician in the 1960's and it was policy to install PF correction capacitors to reduce "wattless" current. The power utilities charged my employer extra for poor PF correction. Our coal mines contained vast numbers of electric motors from low HP to large 300HP motors, later mines much larger HP's, so without correction we'd have poor PF and the utilities would charge us extra. For many years fluorescent lights had built in PF correction capacitors.

Can we use power factor = 1 or more than that ???

Good concept. Nicely explained. But how o reduce electricity bill.

Yes u r right

But why we use capacitor to chakki motor in 3 phase. Im also a electrician i have practical experience whe we add 11 kvar capacitor in 15 hp motor it takes 10 ampare but without adding capacitor it takes 15 ampare.

This useful video highlights the useless scam devices being sold as energy saving devices which connect across mains plug outlet s.

for domestic in my country, there is no penalty for power factor. we charged by consumption kWh

Sounds great.

How to use capacitor

Very good information.

Is there any other possible way to reduce electricity bill? I heard about diode. Can you explain it please.

I lake your video 👍👍👍👍

Nice to hear the lecture. So the function of capacitor is to correct the Power Factor.

Watt-hr meters measure "True" power, not "Apparent" power. True power is the product of rms current in phase (no phase lag or lead) with rms voltage.

27 amps?? From where this arrived ... Not explained in details,,, We have installed automatic capacitor Bank for our building which automatically switch on and switch off the capacitors to maintain the power factor 0.9 ,,, the overall electricity bill has drastically reduced...

50uf is good...sir. 150 unit for mouth. .,

,,i m from philipines,,really, kvar,,capacitor,,save electricity bill

Capacitor bank will reduce 25 % electricity bill .

It reduces the input current

a power factor of .6 will use more apparent power by your motor running less power, restoring 40% to the grid and you will not be paying for it. Caps are added by the power company to make a pf of one so they get full billing.

but by adding kvar,,capacitor reducing amphere, !!

In short, if the charge is based on KWH , the only way to reduce cost is to useless power.

Yes here comes the point: IS every meter calculating also by cos(pf) ? - If Yes, it makes not much sense to avoid it at private home usage. But I try to as fE a server PC takes 50 Watt at 0.87 pf, and so I had an opportunity to test calculation and result. Adding the calculated 2uF Capacitor parallel to the load, the pf even got worse. So I stuck anyway, but your point makes it take easier anyway ... IF our meter is doing V * I * cos0 ... So far I see the higher the load of more PC and Monitor, the better the pf is getting ... another NOT energy saving solution. Ha

True

Capacitor used to increase the power factor

Capacitor Value to be use to reduce electricity bills

I would say that modern smart power meters may detect the existing PF and calculate pwr consumed as per formula mentioned. In contrast, OLD spinning disc meters turn cogs which moves the revolution counters depends on the number of revolutions to register pwr consumed by customers. In this case, adding a capacitor reduces current and disc spin speed, hence lower meter readings for the appliance used. It was benefitial then, but doubtful nowadays...

Then One my Question sir Every place Bill should e same while ampere is no.matter it is less or high ampere Secondly go for .999 pf not at 0.80 ...why go for only .80

Tell me something, how can a radio station, or television station transmit 100k watts 24/7 and pay the power bill ? Just sayin, someone knows something !

If it really worked, there would be plug-in adaptors with a capacitor inside on the market, I never seen one.

it doesn’t make any change in power bill

So why do we hav cos phi correctors in factoryes...you dont have a clue about electricity metering

Can I use a capacitor to save for my electricity bill? If yes, which capacitor does save more electricity No, you cannot use capacitor to save for electricity bill ! Why ? For this we need to know about power in alternating current Circuit. ! The answer is going to be long ! There are 3 types of power in alternating current : Active power : The active power is the real power, and it is measured in killowatts.(PRODUCT OF VOLTAGE•CURRENT•COSΦ cos Φ being the angle between voltage amd current). Reactive power : The power which flows back and forth that means it moves in both the directions in the circuit or reacts upon itself, is called Reactive Power.reactive power does not do any real work and thus sometimes called as imaginary power. Measure in kVAR.(PRODUCT Of VOLTAGE•CURRENT•SINΦ.) APPERENT Power : the vector combination of above 2 power is called apperent power ! Measure in KVA.(product of just voltage and current) Now What does capacitor do ? It stores electrical energy in form of electric field which can supply current when there is change in voltage which keeps it constant ! For ac current it reacts in ac power in which current leads voltage by 90° (ideal capacitor) What does inductor do ? It stores electrical energy in form of magnetic field around it. It reacts in ac power i.e voltage lead current by 90° (ideal inductor) Since almost all ELECTRICAL device are inductive in nature ( microwave oven, induction motor fan, pump motor) this gadgets consume reactive power along with real power which increses current In wire (real power current + reactive power current) and also reduce power factor(pf) In real power the cos fi is also indicates nature of load.for example pf=1 means there is no reactive load.(only resistive)Below 1 to 0 is inductive load. And above 1 there is capacitive load. The more the pf is toward unity the better the power factor(less current) Since electricity board charges only for active power the capacitor cannot generate or consume real power(exception are there). Thus using capacitors is useless for domestic consumer as well as commercial consumer. But wait, Since industries use inductive load it also uses huge amount of reactive power.. Which causes huge amount of i^2r losses in wire resulting in more capacity grid and expenses for electricity board.thus electricity board not only measures active power but also reactive power.Reactive power can be compensated by introducing capacitor not one but many (usually bank which operates as per power factor being bad). This capacitor bank helps in increasing pf. The electricity board penalize the industry for there pf being bad thus capacitor bank helps them maintain good Pf which not only save them from penalty but also get token of appreciation(usually a very little discount )from electricity board for maintaining good power factor. Bottom line : capacitor does not save electricity neither electricity bill. Sorry for long answer. If you like the answer don't forget to upvote !
