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

Thank you for the very helpful video!

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

[@allie_mandalakis]

Great video - very informative!

[@SB-dc9qb]

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

[@robertdale001]

excellent!

can you show me how you got 16570 amps for the 225 kva XFRM at 2.8% impedance? i plugged my values in for that example and i got 22,299 AMPS. im wondering what i did wrong?

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

for 3 phase

Correction: I fat-fingered that one on the calculator. You have the correct number. Thanks for letting me know and I'll figure out how to edit the video!
