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.

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? KZfaq 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 KZfaq today would have been unfathomable on dialup where it took about 10 minutes to download 1MB.

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.

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.

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.

@RofieeTwo 4 жыл бұрын

The biggest problem with most universities teaching EE is their emphasis. They emphasize too much on doing the complex calculation instead of basic concepts. What are we trying to accomplish with those numeric computations? Why is it so important to calculate the power factor? Yes, we know it is for efficiency but had no idea how to correct the problem or that utility company could charge us more (basic economics). Another big problem - fast pace. We cover so many materials every semester that everything is a rush. We don't get to enjoy and reflect back on what we have learned. Having an EE background actually helps me enjoy these videos, like watching a good movie - no stress at all compared to in an actual class. Made me appreciate all the things I have learned in EE. Got my EE degree in San Diego, California.

@dysfunctional4912 4 жыл бұрын

Hello there! I would like to make a observation. In the university where I'm studying they've told us that power output of an induction motor is mechanical (Pmec=τ*ω=τ*2*pi*n/60 [Watts], right?). So, in order to find the power input of the motor which is electrical (P=3^1/2*Vline*Iline*cosθ), they were giving us the motor's efficiency (η=Pout/Pin=Pmechanical/Pelectrical). For example if we have a motor with Pout=10 kW, efficiency of 0,9 or 90%, Vline=400 V, f=50 Hz and cosθ=0,85 then: η=Pout/Pin=> Pin=Pout/η=10/0,9=> Pin=11,1 kW (active power the motor's coils are consuming).

Thank you for the great video. I'm a bit rusty with my EE stuff. Is there a way to calculate the capacitance of the corrective capacitor?

@johnopalko5223 5 жыл бұрын

The cookbook procedure, without going into any theory, would be as follows: 1. Determine the required kVAr of the capacitor, using the method outlined in the video. 2. Divide the square of the voltage by the required kVAr. This gives you the required capacitive reactance, in ohms. 3. Calculate 6.28 times the line frequency (in hertz) times the capacitive reactance, as calculated in step two. 4. Take the reciprocal of the number from step 3. This is the required capacitance, in farads.

thanks for another great explanation! could you (anybody) explain how exactly the current lagging and leading cause the excessive power draw?

can you check at the 2:37minutes... the engr formulas. reactive power should be (kvar) not (kva).

@lakshmanmardi9667 5 жыл бұрын

It should be apparent power not reactive power.

Superbly lucid explanation. I don’t think I could have understood the subject but for this video. I thought that voltage multiplied by amperage gave wattage or energy. Thank youuuuu! 👌

Forever ago I remember watching some garage inventor that got threats from the power company that they would shut off his electricity. Now I understand why they were mad, his "not quite perpetual motion machines" must have had some horrible power factor.

How do you know what size capacitor to use as its measured in farads and you mentioned that youd need a 25.3 kvar capacitor?

@ballsof_steel8957 5 жыл бұрын

Since the Apparent power is Q= 25.3kVar u can use the following formula: Q=wCV² where : V is RMS Voltage w= omega= 2*pi*f where f is the frequency of our system. C is capacity in Farads. if f=50Hz and V=230V then C=Q/(wV²)=25.3*10³VAr/(2*pi*50Hz*52.9*10³V²)=1.52 mF Note you have to use a Capacitor which is rated for the Voltage you are using. I hope i could help you.

Reactive power is not actually useless! It is used by inductive loads to magnetize their magnetic core. Theoretically without reactive power there would be no magnetization, which means no induction motors, no coils, no transformers, only incandescent light bulbs and resistive heaters. In reality it's impossible to restrict the flow of reactive power, it can only be compensated near the consumer. I made an in depth video about the triangle of powers and also deforming power, feel free to check it out.

Reactive power is quite important for engineers and scientists like us but a waste and a problem for electric companies! Reactive power make their generators, transformers and power grid lines to work inefficiently as explained! So if you are a load with a poor load factor they will bill you hard since you are negatively affecting their assets!!
