Can Capacitor reduce our electricity bill ? Power saver device Real or fake @TheElectricalGuy

Can Capacitor reduce our electricity bill ? | Capacitor Connection in our Home
In this video, I have explained about what will happen if we connect a capacitor with the main power supply ? Can electricity bill reduce by connecting power factor capacitor with power supply ?

Thank You
Arun Gupta

Please watch the video carefully and completely before saying that this video is fake, or I am doing misleading.

I made a dedicated video for you on how you can select the capacitor size to correct the power factor 👇👇

Very nice illustration...
Which gives clear idias about voltage, current and power factor..kwh or unit.
This video is creating intrest to know more and more electricity.

I am skeptical about this. I am an Electrical Engineer and understand what a capacitor will do in the US. Most modern large load/motor devices already have a Start Capacitor that takes up the initial load surge. Unlike motor loads (HVAC, Well Pump, etc.), most electronic devices have such a slight surge that this won't be worth it. IMO, upgrading old non-LED lighting, fixing insulation, updating windows, and putting timers (WIFI/automated) on some items will save you a lot more money.

Remember that each device should be power factor corrected with its own capacitor. Because things are switched on and off in a home. Your refrigirator, tv, bulbs, etc. either switch on and off by themselves or you switch them on and off. Connecting just one big cap into your supply, the cap will draw current when you switch off most of your inductive loads and then waste electricity for you, and save for the municipality.

Depends on the area. I use a UPS and it scans the spikes. Got it bc of the ruined Electronics. My power was spiking 200 and was down to 90.. not a steady 120. So I am paying for the 200 but using only 120 . A Capacitor acting as a Reservoir. So I get a steady 120. PROTECTING MY DEVICES .The UPS also is a back up to let my pc shut down in a full blackout. BUT it saves electricity from those 200 spikes thar hit ever 10 seconds and last about 3 seconds. So I am not waistng the surges but saving then for the dims. That hit every 30 seconds and last about 2 seconds and ether surg or dim can ruin equipment. But I noticed my entire electricity bill went down since using the unit and found out it was cleaning the power to a lesser degree for the entire house not just my labtop unlike a regular surg protector that only stops surges not cleans them with Capacitor. It's primarily designed as a backup for laptop. But it's also cleaning my house house of dirty power. So what I am saying is Normally I would be paying for the 180 sudge but only using 120. This Reduces the Problem. My power grids a EXSTREAM example with is why I Got the UPS. But it saves about 15 bollars a month on my eletric bill.

The main reason for a low power factor incurring penalties is because the distribution network has to carry a higher current and thus there are higher heating losses in those cables/ transformers etc. Also, the cables have to be rated for the extra current.

شكراً لك أخي الكريم على هذا المجهود الرائع جدا جدا

[nimaljayathilaka]

Good explanation.very clear. Thanks from Srilanka

[Lacaille]

Maybe this will work when grid consists of mainly of air hanging conduits. (rural areas) But if cables are pulled as ground cables(urban areas), the opposite is often the case.

[lakpriyadil]

Thanks brother, you explained it very well and simple

[pauljanssen]

It's called phase-shifting it works on AC motors to help motor run more efficiently.

[robgad]

Many homes who already use large motors for devices or air conditioning already have some of these in use in the house active circuit. Imagining an AC Capacitor as an energy saver defies the logic and centuries of use of these devices, if anything they are can be a drag on the system and waste electricity needlessly. But what do I know, I'm only an electrical engineer and educator.

[TheGateKeeper]

Thank you for clearing that up for me.

[nilangaliyanage]

Its a very valuable explanation for those who are blindly ticktoky. your explanation is perfect.great.

[eghgbmp]

Thank you for the elaborate and useful explanation.

[slnrs]

Excellent explanation. In market more devices they are selling in the name of reducing electricity bill which has only capacitor inside. You clearly explained that connecting a capacitor across the power supply will not reduce the bill but at the same time will increase the life and efficiency of our house hold appliances which can reduce the maintenance cost of our home appliances in the long run which infact save our money. Thanks once again. YouTube videos are boons nowadays can easily understand any kind of equipment even without basic knowledge also. Little interest only needs to learn about things.

[justsaying]

Seems to me two important qualifications apply here. Firstly the power factor (PF) correction varies depending on the reactive load and that changes as motors, LED lighting and other loads are switched on and off. So the idea that the PF can be corrected by application of a single capacitor is only valid for a given load situation. Putting that aside the other unstated assumption here is that your being billed for the real power component which might be true for domestic households. Large Industrlal users are likely to be charged on total power usage (i.e. apparent power) as a way of discouraging use of high power inducticve loads (i.e. 3 phase motors etc) that do not incorporate some form of PF correction on the equipment.

[timothytamale]

Thank you. it's so embarrassing that I didn't understand this for all the years I spent in university as an Electrical Engineer until now regardless of how may long pdfs I read, they all made no sense. Thank you Sir.

[hosraiyan]

Good video sir, always your explaination understable and clear, Thanks.

Most of the equipment in the house are motor-driven and already have capacitors installed. The biggest culprit is your AC unit. Over the years, the SEER value have improved from less than 4 to greater than 16 and it is mainly due to the improvement to capacitive circuitry.
