Power (P) = 11 kW Voltage (V) = 3-phase system at 400V (common industrial voltage) Power Factor (PF) = 0.5 Current (I) = 35A at PF of 0.5 The formula for current in a 3-phase system is: I = P/sqrt{3} *V * PF Jab pf low hota hai tou current barhega inversely proportional hai, PF low hone ka mtlb hai k ziyada tar current useless kaam mai zaya ho rha hai(losses) tou usefull kaam shi nhi ho pa ra tou usefull kaam(motor efficiency barhane k liye) ko achi trhn krne k liye motor mazeed current leti hai. Tou jab jab pf los hoga motor ziyada current legi kisi bhi kaam ko poora krne k liye
RPM tb barhta hai jab motor ki stator winding mai ziyada current draw hota hai jis se winding ki magnetic field teezi se rotor ki winding ko cut krti hai tou rotor teez ghomta hai or current bhi ziyada draw hota.
Sir ek 200 kw ka motor drive me chalane par ground faults me trip ho jata hai par usi motor ko stater me chalate hai to normal chal rha h ..kya karan ho sakta ki whi motor drive me nhi chal pa rha h ... explanation kre ..
bus coupler do buss ko apas mai connect krta hai do chezoun k liye: 1) Agar ek transformer mai kaam chl rha hai ya maintenance ho rhi hai tou hum dosre incoming panel se bus bar motor ki bus ko couple krdete hain or pehle wale incoming panel ko decouple krte hain. 2) Bus coupler Synchronization k liye bhi use hota hai do buses ko apa mai sync krte hoye
Capacitor Panel LT or MV panel dono hosakta hai, Agar LT motor chalani hai or uska PF improve krna hai tou LT capacitor Panels lagte, issi trhn MV motors k liye MV Capacitor panels lagte hain
Jab motor VFD k saath connected rhegi tou agar uska megger krienge tou megger sirf actual motor winding ki values nhi dega blke Vfd k internal component bhi megger ki values mai part le rhe honge. 2) Safety precaution k liyr bhi nhi krte megger kui k wo 500-1000 V tk mak motor ko test krta hai tou agar VFD connect rhega tou VFD ki circuitry kharab hosakti hai. 3) Agar megger krna hai tou VFD ko disconnect kr k krte hain
Clarity in concept. Awesome sir.
Good and informative, I request you to please share control drawings of starters also.
Sir, Next video on Interview questions of NIFPS system..❤
Nice 👍
Thanks
Super 👍
Nice video
Nice video ❤❤❤❤❤
Sir please make a video for cause of motor troubleshooting
What are the different types of potential transformer like IVT and CVT
What are the different types of vacuum circuit breaker
What is the breaking capacity of vacuum circuit breaker
Nyc
What is ER TRIGGER in SEL relay?
20hp ki motor he use 7000 rpm ki motor ko design kese karte he. Normal 20hp ki motor ke bhi vfd se 7000 rom pe chala sakte he kya?
What is the difference between step down and step up transformer make a video on that sir
Sir please make a video on HG fuse
Before change over of incomer what we have to see
Mere yha bhi all motors delta connect Hai Mere abhi industry me star me koi motor connect nhi ki hai
Angel of Buchholz Relay ??
Is vacuum circuit breaker an medium voltage breaker
Nothing is medium voltage
Low voltage, High voltage and extra high voltage (LT, HT and EHT)
VCB is used in HT and EHT line both
Is lt motors also known as delta motors sir
Is vacuum circuit breaker used as outdoor
Both
Sir किस टाइप की मोटर को स्टार डेल्टा स्टार्टर से चला सकते है और किस टाइप को नही

Ek 11 kw motor ka full lode current 35 ampere hai,power factor 0.51 hai, power factor kam honese current kese rise hota hai...?? 🙏🙏
Power (P) = 11 kW
Voltage (V) = 3-phase system at 400V (common industrial voltage)
Power Factor (PF) = 0.5
Current (I) = 35A at PF of 0.5
The formula for current in a 3-phase system is:
I = P/sqrt{3} *V * PF
Jab pf low hota hai tou current barhega inversely proportional hai, PF low hone ka mtlb hai k ziyada tar current useless kaam mai zaya ho rha hai(losses) tou usefull kaam shi nhi ho pa ra tou usefull kaam(motor efficiency barhane k liye) ko achi trhn krne k liye motor mazeed current leti hai.
Tou jab jab pf los hoga motor ziyada current legi kisi bhi kaam ko poora krne k liye
Sir motor rpm Kam kese hota he or Jada kese hota he pls ek video banao
RPM tb barhta hai jab motor ki stator winding mai ziyada current draw hota hai jis se winding ki magnetic field teezi se rotor ki winding ko cut krti hai tou rotor teez ghomta hai or current bhi ziyada draw hota.

What is the difference between buscoupler and busbar plz make a video
bus coupler do buss ko apas mai connect krta hai do chezoun k liye:
1) Agar ek transformer mai kaam chl rha hai ya maintenance ho rhi hai tou hum dosre incoming panel se bus bar motor ki bus ko couple krdete hain or pehle wale incoming panel ko decouple krte hain.

Is capacitor panel an LT panel
Capacitor Panel LT or MV panel dono hosakta hai, Agar LT motor chalani hai or uska PF improve krna hai tou LT capacitor Panels lagte, issi trhn MV motors k liye MV Capacitor panels lagte hain
Dear Sir, motor agar VFD thru chal Rahi hay Tho Uska Megger Kuy nhi lete aur Lete Hay Tho Kay hoga?
Iska Ek Video Banayi pls
Jab motor VFD k saath connected rhegi tou agar uska megger krienge tou megger sirf actual motor winding ki values nhi dega blke Vfd k internal component bhi megger ki values mai part le rhe honge.
2) Safety precaution k liyr bhi nhi krte megger kui k wo 500-1000 V tk mak motor ko test krta hai tou agar VFD connect rhega tou VFD ki circuitry kharab hosakti hai.
3) Agar megger krna hai tou VFD ko disconnect kr k krte hain

Sir wheen you say numbers values please say in english we are not understand numbers in hindi
Please go English channel
hello sir 🙏
Sir mera siemen transformer ltd company selection huaa h kesi company h join karna chaye ya nhi
Post kya hai, agar production me hai to maat Karo.
