Hi sir I used to watch ur vedios up to date I had interview question last week They asked 1500 kva transformer main in comer cable how much sqmm as well as secondary how much sqmm use
மிக அருமையாக விளக்கம் கொடுத்தீர்கள் உங்கள் பணி தொடர்ந்தால் தமிழ் electrical மாணவர்கள் அனைவரும் சிறப்பு பெறுவார்கள்
Please Make the another Interview Q&A Related Electrical Maintenance Video. Thanks for your effort.

Sir two transformer secondary winding parallel conditions possible or not
My long time doubt is cleared. Thks
Hi sir, epdi irukinga ,namma jamnager site la meet panirukom sir,my name thangaraj Voltech sir.nyabagam iruka sir.
Good explanation bro
Wish u happy Christmas sir
Nice explanation sir we like from andhrapradesh
Well said sir.thank u
Hi sir
I used to watch ur vedios up to date
I had interview question last week
They asked 1500 kva transformer main in comer cable how much sqmm as well as secondary how much sqmm use
Gis 132kv to 30mva transformers 240sqmm single core used but 30mva to switchgear 630sq single core *3 used, why differently use load side
Good explanation
Hi anna stability test pathi vidio podunka anna
சூப்பர் 👌🏼
please explain about silica gel
Nice sir
Sir pls make video on how to read control diagram
Sir motor winding starting led ending led yappate kantopitegurathu sir.ple explain....
Solar module parallel series and both connection oru video potunka
Next video update is about motor cable calculation, sir.
Transformer types of testing ora video poduga
Please explain 11kv Variable speed drive working principle.(nidec).
Sir CT termination.... Pathi sollunga.. Sir
அருமை
வாழ்த்துக்கள்
Sit video lam uploaded pannunga
Unga video pakka na wait pannikittu irukkan
Ammeter la CT ratio etha vachu select panranga? Ex 40/5 ithu Mathiri?
Motor FLC 73A .. so CT Ratio 100/1A or 100/5A , normally CT Ratio , Equipment FLC + 20 to 30%
Normally more than the Equipment full load current
@@rajasaminathan194 hmmm okk
Super explanation sir
