Calculating Fault Current using transformer impedance

What is transformer impedance, how is it measured and how does one calculate the available fault current? The math along with a demonstration of how a transformer is tested is explained in this video. Videos on this channel are an extension of electrical continuing education classes I teach in Eastern Washington State. Check out more info on our website: www.inw-training.com

Correction: I fat-fingered the solution to the three phase problem: As shown the solution is about 22,306 Amperes

Sir. It's a Great experiment explanation. Many viewers really appreciate it... Keep up the good work and God Bless:-))......

Thank you for the very helpful video!

[@allie_mandalakis]

Great video - very informative!

[@SB-dc9qb]

Heck yeah!!!
Can you start uploading podcasts again on the code? Thanks!

Hi, I’m new to your channel. Very educational. Thanks for sharing!

[@robertdale001]

excellent!

Great Video. Is Current SCA = 14.6A on the Primary or Secondary side?

[@dblake32]

Notice that you calculate the short circuit current using either the rated voltage or the rated current of the secondary. That should give you a hint that the SC current you are calculating is on the secondary side of the transformer.

Hello, for some reason, I get a different answer on my calculator. 225x1000/(208x1.732x0.028)=22,305.56

Correct. Please look at my pinned comment. Should be first comment in the comment section. Thank you.
