सर जी नमस्कार आपकी videos से बहुत सीखने को मिलता है मेरा एक सवाल है चाहे तो उस पर video बना के बता देना या मुझे reply कर देना। जो भी फेज preventor लगते वो incoming मे लगते है अगर mcb, contactor और overload के बाद जब मोटर केबल connect कर दी अगर मोटर केबल का कोई वायर break हो जाए तो इस condition मे circuit मे कोन सा switchgear मोटर को safe रखेगा? या मोतोर् ज्यादा current draw करने लग जाएगी और overload control circuit को ओफ् करेगी परन्तु दो windings मे तब तक ज्यादा current flow होगा जितने time बाद् overload relay अपना काम करेगी। आपके reply का इंतजार रहेगा। धन्यवाद
Sir aape videos sbhi ke liye bahut hi useful aur informative hote hai mera question hai ki industry me kisi bhi induction motor ki rpm ko bina vfd ki help se increase or decrease kar sakte hai kya Ex kisi 15hp ya kisi bhi range ki motor jo run condition me hai or jiska Ns 1500 rpm hai & Nr (1450 approx) rpm hai kya hum eske rpm Ns1650 aur Nr ko 1600 rpm tak kar sakte hai (without vfd use ke )kiye kya motor ke winding data ko change karke kjya ja sakta hai kya please reply to me of my question Thanks

Cable voltage drop pe video banaye Under ground cable k liye konsi conditions consider karni hoti he or Overhead k liye konsi conditions full fill karni hoti he
Sir koi bhi size ka cable ki ir value kam se kam kitni honi chahiye ki jis se hum usko use me le ske, jese ki apne motor par vdo bnaya hai ese cable ka bhi bnaye pls sir
Sir i am your new subscriber Working in Steel industry my question is we have two type of blower motors one is delta connected and other is star connected but RPM are same at 415 v plz explain.
Star connected motor or delta connected motor dono hi same RPM ki market mein available hai. Hume kaunsi chahiye ye depend karta hai ki hamari requirement kya hai.
@@electricalwithabhishekjoshi thanks for replying Sir aapki bat sahi h but mera confusion ye hai jb star to delta me kisi motor ko start krte hain tb star me speed km rahti h delta me rated speed pe aati h to ek motor star configuration me rated speed pe chalne ka logic explain kijiye. 2.2 kw star connected rpm 2880 7.5 kw delta connected rpm 2880
Megger me voltage ki value kya honi chahiye aur kyo? Please explain in details ye hogi kuch achi information Is video ki summary 1 Mohm per 1 kV and minimum 1 Mohm for less than 1 kV
Sir, May i know what is reference of your teaching.From where you get the values.How you are telling that for 2KV motor 1 mega ohm is sufficient and also KV +1 mega ohm rule.So that it will be useful for the viewers.
Sir, To predict the health of Motor also required to measure the winding resistances of all three . Please make the video on minimum winding resistance values for healthyness of Induction Motors. Thank you very much.
Sir agar motor ka hp bada diya jaye to resistance me kya difference rahega. Example- 1hp ki motor ki winding ka resistance kya hoga. 5hp ki motor ki winding ka resistance kya hoga
Sir, what should the resistance value for transformer minimum , why transformer is conducted both IR and winding resistance tests to it please make video on it sir
Sir radhe radhe Jes ki 22kw ki moter ka flc 39 hota , mere questions yeh ki wah Star delta me run karti h to sir uske six cable point pe paryatak point pe kitna current aana chahiye Iska koi formula bhi h to beta dijiye AP ka bahut bahut abhari rehunga
Jab motor ma megger ok cable okay ata ke fir bhi fuse instant udte he to khte he ki uska inductance week ho gya he. To inductance measurement ke upar video bnaiye. Vo kb krna pdta he ?
Sir Aap ka samjhane ka trika bahut hi acha h
Me aap se hi bahut kuch sikha hu such God bless you sir
Your coaching is very nice with details knowledge.
Thank you..

Nahi...
Motor speed change karne ke liye VFD, GRR ya SPRS ke through hi kar sakte hai.
Good explain sir...

Sir types of relays used in industries ka ek video bnao sir....Inverse type ..definite type
Good Morning sir
Prectical me possibal h
Kv+1 formula is there . But now ar per IEEE 43 for LT motor IR value should be minimum 5 M ohms
For HT it will be minimum 10M ohms
Thanks for sharing..👍
For HT motor I think minimum IR value is 100 mega ohm according to IEEE 43
For HT its 100 mega ohms
