Q:What do I need to consider or what formula I can use to calculate Z (Impedance) in a Transformer?
It's pretty difficult to calculate the impedances (there's more than one) entirely from the transformer's design data. It's easier and more usual to decide on an equivalent circuit (there are plenty available depending on how well you want to model the transformer) and then to determine the parameters by a mix of calculation and measurement. A pretty basic equivalent circuit which refers all impedances to the primary side, has the primary terminals connected first by Xm and Rc in parallel (the magnetising reactance and core loss resistance) and then by a third parallel branch containg a series connection of leakage reactance Xl, winding resistance Rw and an ideal transformer of turns ratio Np/Ns. Xm is best obtained from an open circuit test but could be calculated as the inductance of the primary winding. For the latter you'd need to know core dimensions, number of winding turns and the magnetising characteristic of the core iron. If you have conductor sizes and conductivities you can calculate the winding resistance Rw, referring the secondary part to the primary by multiplying it by (Np/Ns)². You can deduce Rc from the losses measured on open circuit at nominal voltage and Rw from dc resistance measurements on the windings. If you know the specific hysteresis and eddy current losses of the core material, you can also have a good stab at calculating Rc. The leakage reactance is quite difficult to calculate from first principles - even designers usually resort to some empirical factors. Basically it's determined from the short circiut test which is at nominal secondary current. The ratio of primary volts to secondary surrent (referred of course) on secondary short circuit will get you close to Xl - you can adjust for Rw which can be determined from the losses on short circuit (core losses are absent here!) or by the two methods indicated above. It's normally Xl that's referred to as the transformer reactance and together with Rc and Rw, the impedance.
Q:Electric transformer winding calculation.?
Basically, the ratio of voltages is the same as the ratio of turns. The currents are the inverse ratio but that kind of takes care of itself if you just deal with the voltage ratio.
Q:can ferro alloy smelting furnace transformer can be converted to higher voltage to handle ferronickel smelting?
You need to provide more information about the original use of the transformer. Nickel smelting is a very specialized application that calls for a 'submerged arc'. Basically, the arc is fairly short and will essentially be submerged in a layer of slag on top of the molten material. It is a semi-continuous process in that periodically, some of molten nickel is poured off. The stream of molten nickel is blasted with water that causes the nickel to solidify into small pellets. Steel melting furnaces, by contrast, involve a much longer arc. The slag layer in the furnace is much thinner, and much of the arc is above the slag. It is a batch process in that once the 'campaign' has been completed, the entire melt is 'tapped' - poured into a tundish either to be cast into ingots or to feed a continuous casting process to make billets, slabs or even plates. There are other smelting processes for other materials - for example, silicon is produced via a smelting process. I would guess that if the voltage requirements of the nickel smelting process are different from the requirements of the original utilization, then it would be necessary that the transformer be redesigned and rewound - something that I would not expect to be very practical.
Q:Parallelling transformers with different turn ratio and rating?
To me it is a typical circuit analysis problem. From an application engineers point of view , to analyse the problem, the following needs to be checked first 1) Open circuit Voltage of both the TRXs 2) Internal impedences of TRXs 3) Total Load to be catered to ( converted to in terms of Z) 4) Ratings of the TRXs ( Rather allowable current that can be drawn from each TRXs) Having known first three quantities , we can make the parallel circuts and calculate the current in each branch ( through TRX1, TRX2, and the load) andtheir directions The fourth quantity will tell us if loading is within limit or not.
Q:Transformer wire color codes?

Q:How do you choose the public transformer capacity?
In the actual choice, should adhere to the "small capacity, dense point" principle Distribution transformer location should be located in the load center, and the power supply radius of not more than 0.5 km. Distribution transformer load rate between 0.5 to 0.6 the highest efficiency, At this time the capacity of the transformer is called the economic capacity. But if the load is relatively stable, then the continuous production of the situation can be selected according to economic capacity transformer capacity.
Q:Power transformer parameters
B. Transformer efficiency: In the rated power, the transformer output power and input power ratio, called the efficiency of the transformer, that η = (P2 ÷ P1) x100% where η is the efficiency of the transformer; P1 is the input power, P2 is the output power. When the transformer output power P2 is equal to the input power P1, the efficiency η is equal to 100%, the transformer will not produce any loss, but in fact this transformer is not the transformer transmission power always produce loss, this loss is mainly copper Loss and iron loss. Copper loss is the loss caused by the transformer coil resistance.When the current through the coil resistance heat, part of the energy into heat and loss.As the coil is generally wrapped with insulated copper wire, so called copper loss. The iron loss of the transformer includes two aspects: First, the hysteresis loss, when the AC current through the transformer, through the transformer silicon steel wire magnetic field its direction and size changes, making the silicon steel sheet internal friction, release heat, Part of the energy, which is the hysteresis loss. The other is the eddy current loss, when the transformer work, the magnetic core lines through the line, and the magnetic lines perpendicular to the plane will produce induced current, because the current self-closed loop Circulation, and into a spiral, so called vortex. The presence of eddy current heat, energy consumption, this loss is called eddy current loss. Transformer efficiency and transformer power levels are closely related, usually the greater the power, loss and output power is smaller, the higher the efficiency, otherwise, the smaller the power, the lower the efficiency.
Q:Transformers and frequency question?
A transformer cannot change frequency. You can change the voltage from 155 v peak to 340 volts peak, but you cannot change the frequency. But you can change the speed of the generator and therefore change the frequency, but I don't know if that is part of the question. usually, I find that if you list the entire question with all the details, then it probably could be answered. But only part of the question will lead to incorrect answers. .
Q:transformers game?
i heard that game is really good on some consoles, but i didn't know that it was coming out for the PC too. any way, you get to pick which side you want to be on. its pretty cool, because when you are a transformer, you get to adventure around the city and blow things up! how much better could it get! um, so yeah,it's sopost to be an action packed game that you would probably really enjoy playing.hope you like it!
Q:Homemade transformer overheating!?
It sounds like the design of the transformer is wrong, or perhaps the windings are loose. Use thicker wire for the primary to decrease the resistance
