My pond airpump shows 190va apparent power and 78w true/used power. 1.58a @ 120v and PF is .41. (measured) btw, I get my data from a constant load like you do when it's running. The variable load of say an air compressor motor might throw a wrench into the calculations but we should have it easy. Cheers.
What I wonder is if the harmonic distortion (I) has any consequence in maintaining the magnetic field in the motor coils. I want to think it's meaningless compared to correcting PF.
Hey Serge great vid as always. But i have a few questions. I have a 115 volts goulds water pump. Can i connect a capacitor to a water pump to improve power factor? The amps info on the plate is AMPS =8.6 /4.3 at 115 /230 volts respectively and MAX LOAD AMPS 10.8 /5.4 at 115/230 volts respectively. Which one do i use.? Also i tested the voltage at the pump as 123 volts with my fluke clamp on meter. Running current is 11.08 amps and running volts is 118 volts as tested with my fluke clamp on meter. When the pump starts i see a fluctuation of 15 - 17.32 amps, and voltage goes to around 108-115 volts. Do i use starting or running current? Which voltage do i use? Do i have to use the values of current and voltage on the name plate or can i use the ones i got with the meter. I see no effiency and power factor rating. The pump is a 1/2 horse power. Can u please get back with answers to these questions, i know its a lot. Will be much appreciated. Thanks so much and keep up the great vids.
This would be better of we could speak in person via Zoom or some other platform. In order to calculate this, you will need to work from the value of running current and the nominal value of the voltage the motor is currently connected to. I seem to recall seeing a document where a manufacturer had a table developed for precisely that purpose.
@@sergelevesque6292 ok thanks so much. what a great vid with demonstration and everything. keep it up. i will use running current and nominal voltage as u said.
@@sergelevesque6292 hey serge just one more thing. I realized my water pump has no effiency or power factor info on the name plate. Is there another formula for power factor? and can power factor be calculated using output power. Thanks again
Very interesting demonstration of power factor correction. Thanks
Crystal clear explanation, even the enigmatic reactive power concept became clear
Great video and very good explanation.
Useful demo
good video, I am going to try on my water pump

Hello from Jamaica. Do you teach classes on this?
