- Star delta starter contactor, o/l relay, mcb & cable size selection
In this video we explain star delta starter electrical component size selection basically we know all electrical component rated in amp so its most important so select proper size component
In this video we select component for 10hp motor
First we select star contactor which is 33% of full load current than select main & delta contactor which 58% of flc load
Than select over load relay selection which is 220% less % more of flc load
Than select cable both type aluminum & copper cable
Than select mcb which is 50% more of full load current
We explain all concept very easily for more information learning about about this topic just watch and learn
Which power supply is more dangour ac or dc
In this video we explain which power supply is more dangour ac or dc
Basically ac supply is known as alternating current & DC supply is known as direct current supply
If we ask any person which supply is more dangour so he gives answer dc because in ac supply we have many cycles and in one cycle supply go two time 0 so in ac supply person may be safe but in dc supply no frequency so person not safe
But this is not true in all condition
Because if any person die with ac supply so his full body will damage & if any person die with dc supply so only his effective area only damage so we understand here ac supply is more dangour
In normal case ac supply 4 to 5 time more dangour than dc supply
We explain all concept very easily for more information learning about this topic just watch and learn

Wah 13amp full load current wala moter ke Liya 8amp ka main contractor kya explain Kiya hai Kya knowledge diya hai😂😂😂
Achcha explain kiya hai sir
13.560*50/100=20.349kaise aaya sir ji nhi samgh me aa rha he
good video
Be happy God bless you, absolutely you do great job,
Good explain sir
Very good information sir
Good job
Thnaks
Super video sir 👍👍👍👍
Good information....thanks
Thanks for your information.
❤
❤️❤️❤️❤️❤️❤️
Seen
good job
very good.
Super videos
Sprrr video
Great
Nice sir
12hp summer sible pump me kitane amp. Ka MCB lagega
P0wer factor rely ki sitting &wirring ka bhy batwo &capicitor salaction bhy batawo
dol ka b slection ka video banaye sir
Please you tell me in short step that the motor is 10 hp in flour chakki then mcb= amp ? And flc= ? Amp and delta=?amp and star = ? Amp and main= ? And connection of coper wire to motor = ? Mm should be you tell me in four step thank you
And contactor = how much amp
Sar mene .MCB kese calkuletion kihe me samaj nehi parahu
👍
namaskar sir ,jo main aur delta ka current hai 7.868 uska 50% extra lena hai na ..jaisa aapke previous video me tha..
I think olr settings should be +-20% of the delta or main current value not the flc of motor. If I am wrong please correct me.
Firstly +- 20% is a selection of olr and setting depend on the motor flc , because in the star connection motor current consumption is 33% and delta 58% so .....
Sir, which electrical devices are used in electrical motor staring.
Full load current se kam rating ka main contactor kaise le sakte hai wo to continue run hone par jal jayega ye logic samjh nahi aya please explain
one thing is missing not mention.
the OLR ratting which is describe in this video.
where the OLR connected after or before. means first OLR then contactor or contactor and then relay
Bhai tumhare hisab SE OLR setting karenge to motor JAL jayega. Aur MCB 125% honi chahiye warna ckt Kabhi trip hi ni hogi
Pls convert video english lacture
Sir timer ka or cantroling nahi bataya.
How to connection amp's meter or volt meter
Star delta me overload relay raiting full load k hisaab se hogi kya
Yas -20%+20%
Star m current jyada hoga phase current equal to line current ....naa ki °sqaure root 3 se devide hoga
Tu chutiya hai wo thik Bata raha,abe chutiye agar current jyada hota to star me q lagata be, purpose to hai starting current Ko kum karne ka iskiye to star contactor use karte hai
@@nadim9473 😊😊😊👍👍
Last answer kaise hai 13.566 Amp kase huaa sir mujhe samjh nahi aaya hai
FLC CURRENT 13.566 HAI LEKIN 58% ONLY 7.868 AMP AATA HAI TO JYADA LOAD HONE PAR CONTACTOR JAL JAYEGA.
Bhai main or delta dono contact mese divided hoke current jaayega
Timer ke bare me nahi bataye sir
Can we use star delta starter for 600KW, 414V induction motor?
Yup
Better to use vfd
Pf 0.85 kaise liya
Cable size doesn't understand..because in star delta starter current will be divided..????
Brother, 50% or 150% for MCB selection.
125 bro.
1sq mm - 4 Amp for AL
But distance is more b/w motor and starter....
It effect on cable size ye or no
which make did you refer for 1 sqmm cu cable is 6A and al cable is 4A
Asap ne 13.566 ka 50% made nekala
Is ke 50% 6.78 aa raha hai
Sir I think isme kai galat information h
Over lode to 58% flc lena hai to over lode ka renge to jyada hai
#kya sir... 13.56 ka 50% nikale to 6.8 aa raha hai.. 20 kaise aaya..😟😟
13.56+6=19.56
#thanks sir... Sir relay k liye 20% hi kyo liya jata hai, agr interview me puche 20% kyo to kya jawab dena hai plz sir bataaye..
🙏🙏🙏
Safety k liye
Nuissence tripping KO rokne k liye
Sir English talking please
Star ka 33% value kaisa aaya ?
Nice video
