small calculation mistake, 625+1225+2500=4350, 4350-3875=475, √475=21.79 is right ans.

असंतुलन के कारण अतिरिक्त नुकसान मोटर वाइंडिंग को गर्म कर देगा, मोटर के ऑपरेटिंग तापमान में वृद्धि से वाइंडिंग इंसुलेशन का टूटना होता है और अंत में मोटर विफलता हो सकती है। यह असर में मौजूद ग्रीस या तेल को भी विघटित कर सकता है और मोटर वाइंडिंग को डी-रेट कर सकता है। इंडक्शन मोटर के लिए 3% का वोल्टेज असंतुलन हीटिंग को 20% तक बढ़ा देता है।

Jab Neutral to earth ke bich voltage 20 volts tak milta hai ise kam kaise karein?
load balance kre, aur earthing ko bhi sahi se kre
Make earthing properly

sure, and 230 voltage hoti hai, current to ampere me mapa jata hai

Dear friend 230 is the voltage. Not a current. 440volt is the difference between 2 phases.
Bro this is due to vector addition of voltage ⚡️

Sir ji 625+1225+2500=4350 h

This neutral current value will get only resistive loads.inductive and led loads will not get this neutral current because there is phase angle difference and harmonics distortion this is my practical experience
resistive load ke upkaran bahut Bade hote hain isiliye vo current Jyada Lete Hain To neutral Mein current Bhi Jyada unbalance Milta Hai, Jabki LED Jaisi chijen bahut hi kam rating ki hoti hai isiliye ye Jab operate Hoti Hai To current bhi bahut kam flow Karta Hai To Aise mein neutral mein unbalance bhi bahut kam Hota Hai
@@ElectricalHelp not understood .write in English
@@noushadkari4636 The devices of resistive load are very big that's why they take more current then it is more imbalanced in neutral also when something like LED is of very low rating that's why it flow very less current when operated so like this also have very little imbalance in neutral
@@ElectricalHelp l told this in my practical experience . Do u have any experience u please prove this in practical side. U please send ur Watsap
I will send videos

Sir three phase supply me red .yellow me to current aa raha hai lekin blue me current nahi aa raha hai aur newtral wire (black) me current aa raha hai aur three phase motor chal bhi raha hai yah kaise ho raha hai.
jaga se main cable aa rahi hai waha se check kro ho sakta hai black aur blue aapas me change ho gye ho

How to keep three phase balanced with equal current when unbalanced,please reply to this question, ss load on three phase cannot be always same
distribute load equally on each phase, connect neutral with grounding, and And balance load does not mean that always equal current flows on each phase,
@@ElectricalHelp what is the benefit of balancing the 3 phases. What if it is unbalanced, is there any harm ???
@@rverma5125 due to unbalance losses are increased and efficiency and life of trf decrease.

Lakin sir neutral main 3 rd harmonic ke karan bhi current flow karta hai na
Generally harmonics just increase the current in a circuit rapidly.
