Your videos have few mistakes, like for selection of star contactor you have to multiply by 0.33 which comes when you divide 1/3 due to three phases of star connection but you said to divide 1/√3. But overall this was an amazing and simplest way of explanation. Thank you for this video 🙂
All your videos are really informative and educational I real appreciate your efforts. but I would like to advise one thing which is use more papers during calculation. you do so much calculations on a tiny piece of paper which makes calculation so mesh up. Thanks.
All videos are very imp for interview specialy for diplomatic study thank you Also add one topic as early about Responsibilities of Electrical Site engineer on project work
in complete details. Please make sure all calculation aspects as all are blindly liking your videos. Many factors you have not considered while sizing Contactor.
क्या ये contactor soft starter का भी कम करता है? एक मोटर वाले ने मुझे कहा है कि आप अपने सोलर सिस्टम के submersible के लिए सॉफ्ट स्टार्टर अगर नही मिले तो 16amp का contactor लगाओ
Hello , I like your videos so much. Your learning style is very good. I have a question to know about How to calculate transformer costing? Transformer buy karne ka estimate kese nikale?

Sir mene Aap se Kitni bar pucha tha ki ME jaha job karta hu Vaha par 25kvar ka capacitor laga hua he VO Sahi he ye kharab he VO kese check Karte he video BANAO YA sir bataeye please 😔😔😔😔😔
Rakesh ji sir, kafi simple hai aapko sirf capacitor ke current ko measure karna hai teeno phase par ak ak karke. Or agar wo ampere unblance btata hai to capacitor kharab hai, Agar teeno phase me same ampere hai to capacitor shi hai. Jaise agr R-11, Y-10, B-10.5 to yeh shi capacitor hai. Or agar R-15, Y-10, B-7 to yeh capacitor kharab hai
Pradeep ji, kafi aasan hai. Aapko kabhi bhi KW to HP convert karna hai to aap KW*1.341 karenge. Or agar aapko HP se KW pata karna hai too HP/1.341 karenge.
@@electricaldost thanks mate..if its 1/3 then its fine..we will get 0.33... But if i remember correctly you said 1/√3 while setting the value for star contactor(at 07.00) ..thats what made me confused...

Thanks.
Good explanation. How 0.33 multiplied in Star Contactor and 0.57 multiplied in Delta Contactor as said 1/√3 in both. Soooo
I agree with you
Yes
Dimag me ghusa hi nahi
1÷3=0.33
1÷1.732=0.57
Thank you sir. Very useful video.

kya yaaar kuch samachnehii chitna speed kam karo
1/√3 = 0.58 aayega sir ji choti se galti hai
Stabilizer kam kaise karta he sar low voltage ko hai kar deta he
Sir please confirm.... FLA se voltage drop 2 to 2.5 %... FLA=FLA + Voltage drop.. but aap ne sirf FLA taken as full load current.... Please reply

Sir,15 hp motor ko dol stater se start karne se high starting current par relay trip kyu nhi hota.please bataye.
Dol starter use nahi hota...
Agar motor ka Amp km hai or contactor ka amp jada hai to kuch problem hogi kya

Aap star contactor ke liye 1/√3 ker rhe hai, aur delta contactor ke liye1/√3 ker rhe ye confusion hai ise clear kare
0.33 to nahi hona chahiye na us jagha pe 0.58kar sakte gai kya
Is it right for star contactor 1/3= 0.33, FLA*0.33=... And Delta/Main contactor formula is 1/root 3=0.577, FLA*0.577=...???
Please answer brother
Acha boltey hai but tuda slow bolo speed jada hai

Sir 1/√3=0.57 aata hai na?? 0.33 kaise?
1÷√3ka value 0,57hoga aur 1÷1,732ka v value 0.57hi hoga ek bar ye video ko khud jarur dekhe
Sir ye video to bahot bar bana liya ab naya ku6h banavo
I didn't get it..means 1/√3 and 1/1.
732 should be same..How did you get different answers like 0.33 and 0.57.. Please elaborate..
Krishnendu ji, 1/√3 nhi wo 1/3 hoga.. Wese √3 kya hai, or iske electrical me kya mtlb hai es topic par video bhi channel par bana rakha hai.
@@electricaldost thanks mate..if its 1/3 then its fine..we will get 0.33... But if i remember correctly you said 1/√3 while setting the value for star contactor(at 07.00) ..thats what made me confused...

Why u use 20 and devision by 1.732 i know what is 1.732 but I know need why use 20 when u silect delta contacter
Current without efficiency???
20 hp motar me kitne ki kantiktar lagi gai
Motor ko hum log delta main q nahi chalate hai continue
1/√3=0.57
Why 415 v is used in calculating FLA
Jruri nhi hai ki aap sirf 415 hi likhe. Waha par aap us value ko rkhenge jo aap motor ko voltage de rhe hai.
