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

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

Sir, analog megger (500v) me 0 se infinity tak dial plate me numbers hota hai. Usme ek 415v 3 phase motor ka megger value 1.41 mega ohms show karne par motor ki insulation sahi mani jayegi yaa nahi ?
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

Thanku sir very useful knowledge ❤️
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

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

Dear Sir
VFD vali motor ka magger value kaise le .
Jo motor 440 pr operate hota h uska resistance k ohm me hoga ya mega ohm me sir
Insulation resistance should be in mega ohms
Accepted IR of HT cables (11kv to 400Kv cables) ?
transformer ke liye bhi same concept rahega sir ?
Bhai 10 hp ka motar 415 volt kitna ohm lega ohm 415 pe 1 mega ohm na chahiye ya hp ke hisab se ohm hota hai
You have not mentioned what voltage megger equipment to be chosen?
Sir transfer par bhi same vedio banaye uska IR test value kaya hona chahiye
