How big (size) can the tertiary winding be in transformer? Can we load the tertiary winding, if yes then how much we can load it?
1 5347What are the causes of unbalanced current on 34.5kv feeder Ia=0.05,Ib= 0.25, Ic=0.15 and In=0.27 prior to tripping current are balance?
1794I have raw material for making Compact-Choke for flourscent lamp of 40 Watts. We are suppose to get 0.4 amps output at end. but we are getting 0.42 or 0.44 amps and above. We have done many testings in different but nothing worked out. Please suggest me how to get the correct output. We are using 1. core winding of 700 windings of aluminium 2. E-shape iron fillings and I-shape iron fillings to surround the winding.

why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?
how to calculate slip ring induction motor stator and rotor currents??
IF I KNOW THE AREA OF CROSS SECTION OFTHE WIRE , WATTAGE OF THE LOAD ,VOLTAGE SUPPLY WHAT IM GIVING TO THE LOAD AND ALSO POWER FACTOR OF LOAD ....... SO GIVE ME FOR WHAT AMOUNT OF CURRENT I SHOULD USE WHICH TYPE OF CABLE?
A 3 phase transformer's (Y-Y) Y and B phase is (Y and B connection not broken) broken from neutral and R and Nutral connection is ok, what will be the relay tripping and why
1.Z transform always lies around ? a) origin b) pole c) zero d) z=1. Multiples Mcqs which is bother me can’t find answers on internet. Some help required with little explanation . Note: this is not homework or related to any test. Thanks
