Hi Abhishek, very informative video. I have query on HT & LT cable sizing criteria, hope you can make video on it or answer over here. For HT cable sizing first criteria is always to find minimum cross section area based on short circuit rating, however for LT same is not consider, also in case consider it is not practical to terminate such higher size cable in small rating of motor ranging from 0.37 kw to 45 kw, also economically not viable solution ( these are my thoughts) whats your take on LT cable size with respect short ckt rating of the system
Plz sir iti technician4 pareshaan ibps pattern pe video baniye motivation imporve ho Raha apke video dekh ke ❤ without fess itna acha studey material cover ho Raha !!!
Sir electricity bord se 3 phase and neutral supply aati hai or hamare building me single phase ki tarh use hoti hai but tino phase k wire and neutral wire same size ka hi Aisa q Agr har phase me 5 amp current flow ho rah hi to neutral wire me 15 amp current flow hota hoga to neutral wire mota hona chaie . Yahan system to single phase ki tarh use hoara hai to system to unbalance hai yahan koi 3 phase motor to nahi chal rahe hai system balance ho or neutral me koi current nahi flow horaha . To neutral wire mota q nahi hai plese help.
If the capacitor of the ceiling fan is weak, the fan rotates slowly, but if the capacitor of the single phase induction motor is weak, the motor does not rotate slowly, after a while the motor stops rotating completely. What is the reason for such a difference? plz make a video on this topic
Nice video Sir, Please tell us that how much DC voltage will apply? Means kitnay dc voltage honay chahiye jis pr transformer winding burn ho jayegi? Thanks
The winding acts as a short circuit across the terminals of the Direct current t(DC) source that leads to the flow of heavy current through the winding resulting in overheating of the winding. Iske liye primary winding burn hojayega, 50volts ke jadha volts diyetho it's start as SC in the winding. Hence we cannot give Dc in the primary side. But when you have the megger test to check the insulation we can inject the DC volts as per the rating of the transformer. But we cannot give the supply of DC continuously. At the time of the insulation test we can give the DC volt for checking the windings of the transformer. I hope you got answer by this.
Dear Abhisek ji Transformer name plate my winding 35,and oil temperature 40 degree hoga, but we are keeping in tripping in 65 degree above, why sir?? Please explain this concept
Sir mai arvind gupta rajasthan me 9 MLD STP plant me ele post pr hu sir hmare yha din ke 2 bje se rat 11 se 12 bje tak voltage 455 se 470 tk ho jata hai hmare yha 630 kva ka transformer hai aur hmare yha 80 aur 40 hp ka pump chalta hai aur 75 kw ka blower chalta hai kya kre kya karn hai
why not heat losses of transformers, you are not using for heating water, oil, in your SORROUNDING economic needs to overcome 😂😂😂😂😂😂use of Engineering Economics 🎉🎉🎉🎉😂😂
