Voltage Regulation of a Transformer

[@AayushDubey_007]

where is the explanation? Formula we can get anywhere !

[@walbattat]

It looked like he was writing on a glass panel between him and the camera, but his writing was not reversed. Maybe reversed the image in post ?

Flipped horizontally

[@ruebzmac7367]

Correct me if I’m wrong, I was told that formulae is not the correct one to use as that is similar to that of motor. Instead it’s vreg= (VNL-VFL)/VNL=ANS*100

[@ZackHartle]

I'm pretty confident it's NL-FL / FL

[@ruebzmac7367]

Ok so I think found that it depends on the standard being applied where IEC states the reference is the unloaded secondary and ANSI/IEEE state the loaded secondary secondary voltage is used..

[@debajyotishaw5672]

In book it's also written Vnl-Vfl/Vnl*100, sir please check

[@vishnunikose5031]

Thanks sir...Ur teaching are very empressive

[@vishalraja1543]

Loved you videos man!

[@ZackHartle]

I appreciate that!

[@Cyril...]

God bless you sir. Please could you do a video of parallel operations of transformers and 3-phase transformers with examples

[@ZackHartle]

I'll add it to the list!

[@dailyamperes]

Thanks for sharing!

[@emre-uc1zh]

What is the difference between percent impedance and percent regulation? Arent they both voltage drop at full load?

[@ZackHartle]

%impedence is more about overcoming the impedance of the transformer Voiltage regulation is the change in output voltage from no load to full load

[@ZerroTo0]

sir, about the Vnl. does the voltage measurement calculation must be done in open circuit on the terminals or close circuit terminals?

[@youssofasiry7233]

Thank you for information if the voltage regulation percentage increases that is good or bad?

[@ZackHartle]

I guess that would be bad. It means a bigger change in voltage as you add load which can be really hard on equipment.

[@calebsaheb3159]

@@ZackHartleYeah, it would be awesome to add these kinda extra explanations on causes, purpose etc. these would give us learners more insight into electrical world.

[@ZackHartle]

@@calebsaheb3159 That's a great idea. I'll see what I can do.

Thankyou 😊
