QQ: This video stops at the calculation of the leading-factor apparent power that has to be introduced by capacitive loads. How would one go from this stopping point to figuring the amount of capacitance one must introduce into the system in order to introduce the correct amount of power factor correction into the system?

Hello Paul, I spent 8 hours today trying to learn Power Factor from my course notes and text book. Became really highly frustrated because nothing made any sense. Then I watched and studied your videos. I first went through Resistance, Capacitors, Inductors and Induction Motors and then I did your entire Power Factor Video including all calcs. I starting with your videos at 22.00 on Monday night. Its now 03.34 on Tuesday morning and I can now say that I have mastered Power Factor. WITH ALL MY HEART, THANK YOU PAUL. YOU ARE MY SUPER-HERO. Your Videos are super fantastic. Please keep up the Excellent work! Regards, Rajan. South Africa

That was probably the best layperson's explanation of power factor, kvars, etc. Many years ago I was brought in to work on an inductive furnace, used to melt aluminum. The system was driven by a motor-generator. On the control panel was a meter labeled KVARS, part of the scale was in RED. We were getting readings in the red, I didn't understand why. We also had a bank of capacitors that could be switched in and out. I spoke with one of our proffesors and he gave me a very good explanation. What we found is that some of the switch contacts on the capacitor bank were worn out and we were unable to change the PF. The switch said we were adding capacitors but in reality, we were not. Having taking power quality classes since, what has changed in a building is the type of load. Much of it today is from switching power supplies in computer equipment, also many of the motors used in HVAC are soft start and variable frequency. One obvious clue is to feel the temperature of the power panel, as the PF drops, the panel gets warmer, from the losses, and we pay for it. I wish I saw this video 30 years ago, very good. Jim

30 years ago? KZread started in 2005 and therefore didn't exist in 1991. Neither did the Internet. Well the Internet did exist in 1991 but was only seen in educational environments for a bit before it started taking off significantly in the public space in 1993/1994. In those early days, downloading a video the size seen on KZread today would have been unfathomable on dialup where it took about 10 minutes to download 1MB.

I used to work in PFC, and this way of explaining the problem, and solutions is first class. It is hard for a non electrical engineer to understand the concept, but most people could get some understanding from this video. Regards.

I'm an Electrical Engineer, and I explained this concept many times. I find this is one of the best descriptions.

Ok, so after reading dozens of text books I've come to the conclusion this is the best channel for me to watch and actually understand concepts.

Mate such a legend. Your lessons are amazing. Such a good teacher as well. Keep them videos coming please.

I WISH I'd have had vids like this back when I was a kid trying to internalize information from various text books on these subjects. MUCH more intuitive than the abstract stuff you get from ink-and-paper. God bless you!!!

I am a newly graduated Electrical Engineer and this videos are amazing, simple yet very pertinent information and explanations, keep up the good work!

Thank you so much Paul for these amazing explanations! Most text books are super confusing but you've managed to find a way to make these easy to learn!

One of the best explanations I have seen yet, well done!

Your analogies really are helping picture these concepts. Thanks for the time invested in making these videos !

It is the first time someone makes electricity easy to understand for me. Thank you!

I spent almost half a day to find the exact video that i wanted. Awesome ! Hats off to your work !

This may be the single best electrical engineering video I have ever seen. Such a clear and practical explanation of what is one of the most complex but fundamental concepts in electricity. Love this.

Man! You have cleared my vision.no one here to explain like this.upload more and more video .you have great knowledge with ease of teaching.

I found KZread channels better than my Electrical teachers Thank you for the good explanation

This 10 minute video, explained it better than my 2 hour lecture did.

The best explanation that I have ever seen!!! 1000 BRAVO

This video cleared my concept of power factor. Before this, I was always confused and ambiguous. Thank you for these elaborative videos and keep it going. This channel is God sent literally

honestly, best ever explanation of power factor for me was that example with a beer glass.. so simple, yet so precise... kudos to you!

La mejor explicación!!! Súper genial Felicidades Y gracias!!!

This is the best way I've seen power factor and VARs explained. The beer analogy was genius. I tried to explain power factor and VARs to someone and found it difficult to lay out the concept without getting into inductive and capacitive reactance. The beer analogy cuts through all of that into a digestible concept for the average person.

Outstanding, one of the best presented graphical and methodology topics I have viewed

Another concise, well paced and info packed video. Thank you.

you are a live saver, i didnt comprehend alot of the basics before seeing your animations...

I'm very thankful on how well you explain the concept as now even though I'm currently struggling in my circuits course, I'm able to realize and connect different concepts in an ac circuit especially about this power factor. Kudos to you and look forward to watching more of your videos.

beer analogy was the best!!! thank you!

Very comprehensive video. Thank you

The concept of the Power Factor has been very well explained. I hope that electronics engineers from our school find this channel. :)

This video helped a LOT! Thanks for making it

Possible correction and suggestion ...at about 2:37 In the True Power formula, I think the label for the first term was intended to be "Apparent Power" (kVA) in yellow or orange, as opposed to "Reactive Power" (kVA) in green. Also in the final Power Factor formula it is hard to tell whether the symbol between the two terms is ÷ or +. I think it is ÷ though / might be clearer.

Gord, good catch. I saw that as well. The last formula, the symbol is a Division Symbol. If you compare it with the Plus Symbol in the formula above, under the radical, there is a clear difference.

Koooooool, science is GR8. I don't even know if they teach it anymore. any kind of science the 3 classes of levers, torque /speed, We had a gr8 science teacher, he had an old telephone magneto from the Beverly Hillbillies . hookt it to a lamp. and unscrewed the bulb. magneto was easy to turn quickly. once the bulb was in the circuit, well friend, more torque needed as the current flowin thru lamp, also flowed thru armature in magneto. all those turns of wire made the armature an electro-magnet and its poles were attracted to the field magnets, that is why there was a 'drag' effect cuz work was being done. It shows from the 1st half of the experiment when lamp was not on and if a voltmeter were hookt across the lamp you would have seen the volts the mag was putting out, yet was e.z. to crank. then when lamp was lit, the work it took to lite it. so amps is the electrical equivalent of TORQUE and volts, the electrical equivalent of SPEED. Hope this helps you understand a bit more of science.

i found it, simple and to the point. thank you

This video is very helpful. Thanks a lot for this amazing explanation.

Tysm!! Never understood these concepts so well before

From 1 query, you have me hooked. Seriously.

Great videos of yours, I appreciate deeply each one of them. I've found the animations particularly descriptive, much more than all the drawings I could see on student books. I did not go through all the commentaries to check whether someone already commented on the slide with the trigono. A minor mistake :. True Power [kW] = Apparent Power [kVA] x cos(Theta) or True Power [kW] = Reactive Power [kVAr] / tan(Theta) but not True Power [kW] = Reactive Power [kVA] x cos (Theta). I guess you meant : equation 1 squared + equation 2 squared = equation 3 squared, so Eq1 should read : True Power [kW] = Apparent Power [kVA] x cos(Theta). Correct ? Also Power Factor = cos(Theta)=True Power/Apparent Power (the division symbol can be confused with a + sign). This was already mentionned in a previous comment. Hoping it helps.

Very helpful! Thankyou very much!

Great explanations.

Another outstanding video so well explained, thank you very much

Thank you for the detailed video on a difficult topic. Have you by any chance covered in other videos the interactions between UPS/no-break (squared waves and true sine waves) versus computer power supplies (high efficiency through PFC vs regular non PFC)? And also how the filtering mechanism (PFC) can actually overload the non sine-wave UPS?

Best ever electric engineering channel.

After many decades of doing operations, maintenance and repair in power substations and not " fully " grasping the concept of kva power factor, which was used for transformers, very large transformers, fan plant motors, pump room motors, compressor motors, overhead crane motors etc. I now have a better understanding of power factor and kva rating than I did all those years working with equipment with a kva rating. To be fair, in performing my job a true understanding was not nessecerry as I had no part in the design and specifications of the equipment, that was the engineering department. I just operated, maintained and repaired the equipment. Thanks for a better understanding.

thank you well explained !

Thank you Paul.
