- Q: A want to know what happens to transformer when it is overloaded. Where i can get information about this
- Yes the transformer will burn and blast if overloaded.It results due to heating effect
- Q: I have a National refrigerator which runs on 110 volts . Since the local voltage supply in my country is 220 volts, my refrigerator has been powered by a step down transformer for the last many years and it was working fine. But now the transformer overheats, emits smoke and burns out. I have got it rewound many times but the same problem persists and the transformer burns after a few weeks . What might be the problem?
- Perhaps the fridge is at fault, drawing too much current from the line. That could be from a faulty compressor or defrost heater (more likely) or fan motors (less likely). Best way is to first check if everything is clean (coil outside/below the fridge should be free of all dust and dirt and if the coil inside should be free of any ice) and if the fridge maintains stable temperature. If that is all fine, then you need to load test with an Ammeter to see if the current draw is within the spec (should be on a label at the back or you can look it up online or in the manual). If the current load is too high, then it is most likely the compressor going bad and will need replacement.

- Q: I know that Cartoon Network showed a couple of commercials for season two of Transformers Animated,but when?To add,the stopped showing those commercials.like,one week after the first time the commercial aired.Did the have second thoughts and decided to cancel it?
- Transformers Animated has been cancelled after the end of Season 3. This was announced at BotCon approximately two weeks ago. Currently, there has been no announcement as to what will follow it in the Transformers TV line, other than that there will be something.
- Q: does anyone have the trailer for transformers
- No there is no trailer yet because there is no footage yet. The film is currently 'in production' and will hit cinemas next year. Look for a teaser soon enough.
- Q: hey all , i have 2 phase welding machine fed from 30A 3 phase circuit breaker , at high loads above 40A CB cut off the Supply . the problem is i cant change the CB size bcoz it Contrary to legislation in the country . Can i used scott t transformer to balance the load at the main 3 phase ?
- When you say you have a 2 phase welding machine, that is not enough information to answer your question with a reasonable margin for success. If your welder is indeed a two phase machine, where the phase angle relationship between phases is 90 degrees and not 120 degrees, and you have a three phase service whose phase relationship is 120 degrees between phases, it is possible to build a Scott T transformer bank that will give you a 2phase 4 wire system. You will need two transformers. One of the transformers will need a center tap on its primary winding brought out and the other transformer will have to have a tap at 86.6% of full winding voltage brought out of its primary windings. Also you will only be able to get about 58% of the nameplate capacity from the transformers for the same reasons you get 58% from an open delta transformer connection for three phase. These will be special made transformers, unless you are winding them yourself, and will be expensive. I suspect they and the special connections you will have to make, will exceed the cost of a new 3 phase welder. Last but not least, if indeed your welder draws 40 amps per phase using a three phase circuit you presently have, other alternatives present themselves. Such as a larger three phase service to allow for the 40 amp load. Also you might consider at least one transformer with a center tap primary and the second one without the 86.6% tap. The secondary will be slightly out of balance due to the higher voltage on one set of secondary (about 14% higher) but it may work for the welder. Hope this helps, Newton1Law
- Q: If it is powered by a DC source, will there be a Back EMF generated? Why/Why Not?Obviously, there will be a higher current flowing than that of a AC supplied transformer, but I don't know why.Thanks.
- A transformer uses magnetic flux changes in the primary coil for induce a voltage in the secondary coil, the relation between the voltages is given by: Vsec N2(dΨ1/dt) (Faraday's law of induction) Ψ1 k*N1*I1 Then Vsec N2(k*N1*dI1/dt) where: N1: number of turns in primary coil N2: number of turns in secondary coil Vsec: Voltage in secondary coil Ψ1: magnetic flux in primary coil I1: current in primary coil k: constant involving Reluctance and others parameters If the current in the primary coil is DC (a constant) then his derivative must be zero, then Vsec 0
- Q: about transformers
- Your logic is valid but a careful look will tell what is happening. This strange behaviour is not that uncommon, it has analogy in other areas also. For example when you push a large stone, it is pushing you back (famous third law), then how does it move at all, if it cancels the supply force? On the other hand when you push a strong wall, it reacts with equal and opposite reaction. The thing is if the wall did not exert this reaction it would have allowed itself to be pushed back without any resistance!! These action / reaction like, supply voltage and induced emf (other examples are terminal volt of a d c motor and back emf, generator output and its reaction on prime mover etc etc) are all must be conceptually understood. I can dare say that they do not exist as such! They are merely way of understanding the concepts. When you supply ac volt to a coil (transformer without secondary load is just a coil) because of energy transformations taking place we see that the coil offers resistance much different from pure resistance, which is called impedance. But the same can be viewed as reduction of available voltage due to induced emf. I repeat this is a conceptual understanding of the phenomenon.
- Q: If calculating the efficiency of a transformer with different frequencies,how can the frequency be altered? For the experiment the voltage applied will have to be constant, is this still possible? or what quantities will be kept constant? and which will be measured to calculate the efficiency? using PVI to then use %(Pout/Pin)*100 would mean measuring current and voltage, is this the best way?
- properly no rely what engineering considerable you elect, you may desire to take Calculus a million 2, Matrices, Differential Equations, Chemistry a million 2 with labs, Physics a million 2 (Electromagnetism). you do not easily declare your engineeing considerable till the top of Sophmore 300 and sixty 5 days in college. Junior 300 and sixty 5 days is once you would be formally enrolled in a considerable. once you word for college and choose a considerable, you at the instant are not easily enrolled in that considerable and you will nevertheless choose any considerable you prefer. they merely ask what considerable you have an interest in to verify you're taking the mandatory situations on your first 2 years earlier stepping into your considerable in Junior 300 and sixty 5 days. interior the 1st 2 years of taking chemistry, math, and physics, you may additionally take Intro to engineering(CAD), and a brilliant form of engineering classes and electives like Statics, Dynamics, power of fabric, Thermodynamics, Into to electric powered Engineering(Circuits), C++, or Fluids. those classes will help you make certain what direction to circulate in direction of. based on your description, you desire Mechanical or business Engineering. the two deal in convalescing performance of goods, machines, and approaches. the two have numerous math. the two prefer expertise of Physics and the two require you to be good in difficulty fixing.
- Q: I purchased a doorbell in Europe, it has a transformer that goes from 220V to 14.8V, will the transformer work on 110, or do I have to replace the transformer?
- Yes but the secondary will produce 7.4VAC instead of 14.8VAC.
