Power Factor Explained - The basics what is power factor pf

What is power factor? In this video we learn all about power factor starting at the basics. We cover, what is power factor, what is good and bad power factor, how to fix bad power factor, what is leading power factor, what is lagging power factor, how capacitors, inductors and resistors affect circuits as well as how to calculate the power factor correction.

I'm an electrical engineer of 30 years and I'm telling you now I couldn't think of a better source of engineering information than this channel. Its so well put together and explanations are (99.9%) of the time spot on. Paul, I've said it before I wish you were my college lecturer many moons ago! Keep up the good work

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.

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

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.

[aaronramsden]

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.

[matheoscolettowermuth]

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

[moistmike]

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!!!

[byronjones]

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

[sergiosaenz]

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

[aaronramsden]

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!

[Tenshiwa]

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

[jeanpaulkyokya]

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

[navassharif]

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.

[rahulbalaji]

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

[SS-rkbu]

I found YouTube channels better than my Electrical teachers

Thank you for the good explanation

[NTHN]

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

[ibeatits]

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.

[pahvalrehljkov]

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