Sir apne ye bola ki Delta me jyaada leti h current or last me star bta rhe ho
Very fine
Sir aapne pehle bola delta me zyada current legi, aur calculation ke hisab se star zyada current le rahi hai to right answer konsa hai??? Delta ya Star??
Yes. Write ans kya hai
Yes.....????
Star
Sir plz confirm me about current
Star
बड़ा confusion है भाई ! शुरू में आपने बताया कि delta वाली मोटर ज्यादा करेंट लेती है, बाद में prove किया कि delta वाली मोटर कम current लेती है !
ये ही बात मेरी समझ मै नही आई 👍🙏
Shi bol rhe ho... confused ho gya m
4.52 par aapne bola delta mai jyada current leti hai,but delta mai kam leti hai current,dhyan se bro
th-cam.com/video/nN5XI5VzB6U/w-d-xo.html
Sir your video is very good and will understand thanks sir ji
right, he wrongly explained at 4:46, he was supposed to say that in Delta connection motor takes more voltage and less current
Motor star me kam current leti hai
आप बहुत अच्छे तरीके से समझाते हैं धन्यवाद् 🙏
th-cam.com/video/nN5XI5VzB6U/w-d-xo.html
Video me sudhar kare sir aap ne pehle delta me jyada current bataya or last me star me jyada bataya he concept clear kare .....dhanywad
Sir, aapne pahle bola delta me jyada current leta hai,
Lekin proof kiya ki star me jyada leta hai. I'm confused
Mujhe bhi clear nhi hua hai sir?
सर मेरी जॉब लगवाने में कहीं ना कहीं आपका योगदान है 🙏
किस में लग गई आपकी जॉब

Congratulations
Congratulations 🎉🎉🎉
Congratulations 🎉🎉🎉
Very nice
First comment nice Sir 👌👍👍
Shukriya support ke liye Mam
Bhai apne pahele delta connection vali motor jyada current leti hai bola ...
OR
Last mai to star connection vali motor jyada current leti hai ..
Asha kyu sir ...
Hum galat hai yaa aap 🙏
Plz answer me sir 🙏
Aapka star aur delta voltage distribution wrong hai, please isko correct kijiye, baki video bahut achha hai.
In Star connection :- line voltage = √3phase voltage
Line current=phase current
''''''''''''''''''''"""""""""""""""""""""""""""""""""""""""
In Delta connection :- Line voltage=phase voltage
Line current=√3phase current
"""""""""""""""""""""""""""""""""""""""""""""""""""""
Delta connection me √3 gunna jyada current leta hai🙂🙂
पहले आपने कहा के डेल्टा ज्यादा करेंट लेती है अब गणतरी करके आपने स्टार कनेक्ट ज्यादा करेंट लेती है सर समझ में नहीं आया डेल्टा करंट ज्यादा लेती है के स्टार ज्यादा लेती है ?
Apne kaha ki delta connection me current jyda leti h... but example me opposite ho gya?😁
Ha na😂😂😂
Aap phle bolte hn ki delta m jyaada current le ge last m star connection m jyaada bta rhe hn sir plz 🙏🙏 glt mt pdaooo
Amit Ji, bech me ak jaagh glti se delta bolna me rhe gya Iske liye Sorry, lekin last me calculation me aapko clear answer mil gya hai.. Ki hmesa motor Star me jyada current leti hai, kyuki Motor ke andar hm voltage kam de rhe hai..
@@electricaldost thanks for reply sir
Lekin apne apne hi is video meth-cam.com/video/6k93wGQZzTc/w-d-xo.html bataya h ki delta me jane wala current phase current hota h, kyuki isme 2 R, 2Y, 2B jate h.
सर, अगर motor star connection में current ज्यादा लेएँगी तो हम star delta starter क्यों use करते हैं
To reduce inrush current
Good 🎉🎉
Sir agr star me jyada current leti h to pir hme motor ko Delta me he chalana chahye star q chalate h phle hme Delta me chalni chaye motor
Which motor run higher speed star or delta connected
Thanks sir
Tu to maroge maroge sir kya interview main Hume bhi marwayega sir please correct answer.
Sir AAP plz thoda dhere dheere smjaya kro AAP bhaut jldi jldii smja dete ho
Sir aapne pahle bola tha ki delta me jayada current leti lekin calculate karne par स्टार me jayeda current le rahi h
*P=√3VICosφ*
P=constant
V=constant
Cosφ=constant
Then I=??? For ★ & ∆
Volatge can't be constant in both Star and delta, as we give phase voltage in Star connection and Line voltage in delta connection.
@@umangmakwana12 *My point is Current=less then power=also less*
Applied Voltage are always constant...
No mater motor star connected or delta
Because incoming line at our home is around 415V line to line in 3 Ph.
Nice
Sir 1 baat hai humara heater hai oh hai 150kw ka star cunection mai load check kiya clamp meter se to 195amp aata hai or ohh delta mai chalana ho to kitna current lega???
बड़ा confusion है भाई ! शुरू में आपने बताया कि delta वाली मोटर ज्यादा करेंट लेती है , बाद में prove किया कि delta वाली मोटर कम current लेती है ! 🙏🙏🙏🙏🙏🙏🙏🙏🙏
Pl give me knowledge of 220v three phase Delta motor run by 220/30v single phase and three phase friquncy drive. Onther what's it's maximum limit ( motor KW like 2.2,4,5.5kw) get good load and rpm
Bhaut badia mai commerce student hu but I got my basic correct. ...
Thankyou
I think more current in Delta connection as compared to star connection. As more torque means more current. Kindly correct me if I am wrong.
Salute you sir
Sir star and dalta coniton me phase current me kam currant or line phase me jada currant ku leta he
th-cam.com/video/nN5XI5VzB6U/w-d-xo.html
Pahle aap ne Delta me jyda current legi Or fir bad ne star bra diya wo kese
pehle bole delta me jyada legi current
Good explanation.... Send me how to work in meggar...sir
Go to electrical gyan with trinath you will get the video
Sir, first you told Delta connection will take more current, but after calculation it clearly shown, star connection took more, will you please clear it.
He is telling lie. He doesn't know anything about electrical engineering
सर बहुत खूब..... आपके ज्ञान, विद्वता व प्रस्तुत करने के तरीके को सादर सैल्यूट,,
सर इस वीडियो में थोड़ा कन्फ्यूज हुआ है कि आपने पहले डेल्टा में ज्यादा amp की बात कही है लेकिन लास्ट में स्टार में ज्यादा amp बताया है,, कृपया क्लियर कीजिये।
th-cam.com/video/nN5XI5VzB6U/w-d-xo.html
Vidio ulta hogaya ,in star connection motor will take less current,in delta motor will take high current then star ,I think u are wrong please check it again for proper clarification.thank you for your valuable information for us 🙏🙏🙏
आप ने पहले बोला डेल्टा कनेशन ज्यादा करंट लेगी कैलकुलेट करने के बाद आप बोल रहे है डेल्टा कनेक्शन कम लेगा
हा sir पाहीले Delta बोला aur last main star
Sir sub submersible water pump 1hp ka panel connection kaise kare.
Something is really worse in this video....
How can you make a delta to take less current......
BASICALLY star use less current ..so that in staring less current would be drawn out of the supply.....
Then after starting... Delta connection will be active....delta uses more current then star.......
Plz correct this ..or Remove this video...
Its a huge mislead
Hello sir my question is: Sir 10hp ki submersible moter उल्टी घूम रही है या सही कैसे पता करें? और मोटर उल्टी घूमने पर ज्यादा करंट लेती है या कम? अभी मेरी मोटर 25 amp ले रही हैं(starting current bhi 25 amp ही लेती है जबकि मैंने सुना है कि 10hp की मोटर starting में ज्यादा करंट लेती है।) और DOL starter लगा रखा है। और दो वायर चेंज करने पर 40amp करंट लेती है। और 40amp पर मैंने 2sec ही चलाया था क्या हम मोटर को 40amp पर अधिक देर तक चला सकते हैं। बताये सर। कौनसा कनेक्शन सही है 25amp वाला या 40amp wala.
Sir delta me to 415 volt ka current jara aur har winding ko aur uska amp kam kyun dikha raha
Aur star me 220 to aur uska amp zyaada aara aesa kyun
Plz samjhaao ye
Star delta cleared👍
भाई साहब आप ने वीडियो सही बनाया लेकिन सही समझाया लेकिन कुछ गलत बोला है आप ने कहा कि डेल्टा कनेक्शन मे ज्यादा करेन्ट लेगी बाद मे स्टार कनेक्शन पर ज्यादा करेन्ट आया कोई बात नहीं बड़े बड़े इन्जीनियर से गलती हो जाती है लेकिन इतना बड़ा वीडियो बनाने की जरूरत नहीं है सीधा सीधा ये होता है कि जहां पर वोल्टेज ज्यादा होगी वहां पर करेन्ट कम होगा और जहाँ वोल्टेज कम होगी वहां पर करेन्ट ज्यादा होगा इसी से पता लग जाता है
0.5 hp me star cone. Hota hai aur 20 hp ka bhi winding change karke full load star mai bhi chala sakte hai .
This is Rong information because delta conetion 415 v and star 240 volt star 15 amp and delta 8.7amp more voltage delta conetion but amp lower case aposit star connection 240 and amp 15 high correct ansr delta conetion more voltage and amp
But starting good information and end Rong information not sticfide information this video
मैं एक यही कन्फ्यूजन मुझे था लेकिन मैं प्रैक्टिकल किया तो मैं main mcb पर क्लैंप मीटर के देखा तो स्टार में काम करंट ले रही थी डेल्टा में ज्यादा सर आप एक बार जरूर बताएं
Jai ho
Aapka video me last tak dekha
Aap to explain kiye star connection me jyada current Lete hai
Phir middle me kaise(about at 4.40 minutes of the video) bol diye delta connection me jyada current leta hai ?
*Kindly be careful when explaining.*
Also rectify the video.

ic ne ratta lagaya hai logo k concept k sathe play karta hai chand paisy kamany k liye. note that when voltage is high ampere should be low, when ampere is high voltage should be low. so 240volt take max current.
4.55 पर बोलते हो डेल्टा में ज्यादा करेंट लेगी ,
लास्ट में बोलते हो स्टार में ज्यादा करेंट लेगी,
भंग पी ली क्या भाई??
Sir star connection me 2 windding ko 400volt deta to uske hisab se 1 phase windding ko 230volt milega to star me phase current, delta connection k phase current se 1/1.732 kam hoga.
Delta me line current=phase current×1.732 amp ,isiliye star windding me motor 1/3 power leti hai aur delta me full load.
Agar sabhi windding ka resistance/inductance 100 ohm mankar star aur delta me current nikal k dekh le
Espe कुछ गलतिया है कृपा करके एक और एक वीडियो बनाये🎉🎉🎉🎉🎉❤❤❤❤❤❤
This video is conceptually a disaster..Star connection takes less current than in Delta connection and this fact is basis for Star-Delta starter..In Star-Delta starter, motor is first started in Star connection so that starting current can be less and abnormal loading to the system can be avoided and only after sufficient delay motor is switched to delta connection...
Also, calculations shown for current in Star connection is also flawed..
मुर्ख, तु मोटर वायंडींग करंट कॅलकुलेट करके बता रहा है. दोनो कनेक्शन ने पाॅवर सिस्टीमसे खिचने वाला करंट सेम रहेगा.
Star mein jyada current kyun leti motor star connection tho high current ko kam kartha hi na
Bhai star winding motar me 1.732 root 3 ki value ko multipli nhi karte.. Angle bhi pdha rha h phir bhi.. Pgal bna rha h... 5 hp ki motar star me 6.5 amp.. Leti h
Sir vedio ke starting me aapne bataya ki Delta me jyada current leti hai or after calculation aapne dikhaya ki Star me jyada current. WHY????
According to this video star connection is taking more current so why do we connect in star first at the time of starting of motor pls help anyone
Aap galat kah rahe ho. 5kW motor star connected hai toh current kam legi, aapne 15A kah diya hai wo sahi nahi hai. Motor ki power delta connection me de di jati hai. Isliye wo motor star connection me 5kW ki nahi rah jati, isliye 5kW ke hisabse calculation star me karna galat hai.
Star conection me jyada 15amp power le raha hai
Delta me 8 amp
Aap start me bol rahe the ki star me kam current legal 😀
Galat h aisa nahi hota h star me motar hamesa kam current leti h prectial ke ke dekhna me ne prectal kr ke dekh liya h vo bhi full load pe 4 kw ki motar Delta 5.5 amp curent le rahi thi wahi motar star connection krne pe 1.5 amp current le rahi h aur motar full load pe chal rahi h 1 year ho gaya h S1Deuty h motar mera mobile no 9887933804 h aap bat kr sakte h
4.43 aap bol rahe he ki delta connection jyada current leti he...last me kaha star me jyada current leti he...kon si baat sahi he bhai??
*agar star connection me jya current leti he to star-delta starter me motor ko pehle star me kyo chalate he...starting current ko kam karne ke liye star delta syarter use hota he to star me chalaenge to jyada current legi aap ke hisab se....
please explain.....
Ac Traction motor me high starting torque chaiye aur current torque se proportional hai to star connection.. lekin train me uske baad speed k liye voltage chaiye to delta connection... To kya usme Star delta connection use hota h kya
Root 3*V*I*cos phi. Me V and I line voltage and current hoga.
Motor star me current kum lenge
Sir apne to kha th ki delta connection mai jada current leti hai ,aur ap calculation mai star motor ka bata rahe ho ,maine practical 7.5 hp no load motor run kari th to star mai current 1.6 , 1.4 , 1.4 th aur delta mai motor ka current 6.4 , 6.5 ,6.7 th
U just said motor took current more in delta but by calculation u show star take more current than delta connected while motor power same actually u confused or I tell me in comment or nex video
Very nice sar ji
Sir mera ik doubt he ki hum jab 3 phase motor me Star connection karte he tab hum motor ke 3 terminal short karte hai aur fir hum 3phase supply dete he तो star connection me winding short q nahi hoti
Dear hamare yaha pr ek moter thi usme w1 ke samne w2 & V1 samne V1 & U1 ke samne U1 tb delta connection kaise karenge
w1- w2
V1 - V2
U1- U2
4.45 calculation wrong huwa bhai star me kabhi bhi zyada current lagi 5 sec bad delta me convert hogi
5 HP motor star connection me without load 3 se 4 amp. Tek legi or load per 6.5 se 7.5 amp.
Bhai hasab to sai karo kabi ap bol raha ho ka dalta zadia current lati hai kabi star lati hai mantal
Sir phale app ne dealta. Connection me jayad current leta hai bola bhir uske baad ampear nikale to star conection me jayda current lega bole. 🤔🙄
First video I dislike your Chanel because You create a confusion first telling delta or last saying star what is this
Thanks for 🎉
Pahle keh rahe thhe delta jadda current letti hai fir math kiya to star jadda current laenne laggi kase????🤯🧐🙄🙄😐
Wrong concept @Electrical dost, Delta connection takes 3 times more current than star, thats why star to delta circuit used to start a motor
Then why big motor first start in star and then delta
Bhai pahele Bola Apne ki delta current zyada leta hai fir aal bata rahe ho ki star zyada current leraha hai Kuch samjha nai Bhai........
Very good सभी प्रकार के conseft kiliar ho gaye
Pehle aap Delta zyada current leti he bol rhe h lkin caculation me Star me current zyada le rha h.... 😢😢😢
Sir aapne video me pahle to bataye the ki delta me moter jayada current leti hai or jab calculation kr ke aap
Bataye to calculation k hisab se to star connection me jayda current le ri motar 15amp or delta me 8amp
Without multimeter how to check wire,battery & other thing continuity
Sir aapne pahle bola hai ki delta me jayada current legi phir sabit Kiya ki start me jayada current legi
Sir ap jut bolo rehiho or ek video Mai ap bolothe Delta Jada current le rehi hai ABI bolo rehiho star Jada current le rehi hai
Thanku sir
Aisa confusion mt creat kro bhiy...life ka sawal h logo ke...
गुरु जी एक वीडियो रजिस्टर कलर कोड से ओम के कैसे पता करते है बनाईए 🙏
Kuldeep ji channel par video already bana rakha hai, Aap check kar sakte ho
Confused kar diya aapne to pahle delta jyada legi aisa bola .. Fir calculation me star jyada load le rahi he..
Sir liken star delta starter m pahle motor ko star m Chala k Kam voltage dete h to wah Kam current Lete h fir delta m chalte h to us ko line voltage dete h .plz clear it
Sir galat bol gye aap pehla delta jyada ko jyada current de diya fir star mein jyada kr diya.....🙄
Kabhi DELTA me
Kabhi STAR me kuch samj ni aya
Ap b confuse ho
invatr 220 singl feas 5.5 380v daelta chalegi
Yrrr tere hisab se to 5 hp ki motar 15 amp current legi.. Kya bakwas h 😂😂😂
