Turns Ratio Test (TTR ) of Transformer

This video describes the Turns Ratio Test (TTR) of transformer in detail. The procedure for performing TTR test of transformer in delta and star configurations in explained. The analysis/interpretation of the TTR results is carried out.

Thank you sir. Your video had 1hr of info jammed packed into 6mins. Truly appreciate it.

[veneciousmulenga]

Your explanation is very very much clear and understandable. I cannot hesitate to subscribe

[earnmoney]

Ur videos help me a lot, nice explanation sirr

[tyd]

I turned on subtitles and everytime you say major faults it corrects the words to farts hahaha
thank you for the videos though i am studying to become an electrician

Thanks for your nice explaining


But the equation of erorr I think it well be (actual value - calculate valu) /calculate value*100

TTR test for transformer one of major invergating test transformer with OLTC whenever maintenance on OLTC before and after maintenance on OLTC TTR is performed to compare the result and check the functionility of OLTC up to the mark before put in to services

if on result AB/ab it means HV and LV winding both are connected with TTR b/w phsae if AB/an then LV will be divied on sqtr 3

[engineerkhiyalhussain]

Can u explain that in both cases when TTR increases or TTR decreases, cause is same for both that there is shortage or insulation failure on LV or primary side?

Character In the video It's great, I like it a lot $$

When doing TTR test, Does The Transformer have to be in energized state or not? Thank you.

[akhtarhussainshah]

in y connection if TTR is connected between two phase ther no need to divied the Y connect side on sqrt 3

SIR turns ratio PRIMARY BY SECONDARY OR SECONDARY BY PRIMARY IT IS DIFFERENT IN DIFFERENT BOOKS
