how to reduce copper losses in a transformer
Copper losses are due to the resistance of the copper (or aluminum) windings.
To reduce copper losses the transformer would have to be rewound with heavier gage wire.

How do you calculate copper losses?
copper losses are power losses due to flow of current in the wires or resistances,if the resistance is R, current is I then copper losses are I2R. for a 3-phase system; copper losses are same but for a single line, total losses are 3I2R.

What are the Advantages and disadvantages of delta and wye transformers?
copper losses Comment: Advantages: Their operation is silent They have a high efficiency They are relatively safe Disadvantages Expensive Copper losses and hysteress losses
Can a Auto transformer have more load losses than its no load losses?
Power transformers have both no load and full load losses. The key is copper wiring, as copper varies with the square inches of the secondary and primary currents.
Distribution transformer design for which?
Distribution transformers are used on distribution side not transmission side. Core losses or Iron losses ( Hysteresis and eddy current losses ) are proportional to the square of the voltage. Copper losses are proportional to the square of the current. Distribution side voltage is less compared to the transmission side. core losses are constant irrespective of the load, but copper losses varies with the load. Transmission side transformers are not usually stopped from working by the operator frequently, they continued to work throughout the year until and unless if there is a problem and also they almost have constant load. So they are going to have more core losses. So their core is designed in order to get less core losses. Any way the copper losses will be less since the current is less because voltage is more. Distribution side transformers are having more load fluctuations and more stoppages.Their voltage is low so they will have less core losses, no need to design a better core, but distribution side current is more so copper losses are more, so distribution side transformers are designed to have less winding resistance, so that the copper losses are low.
Is a transformer heat neutral?
All transformers produce some heat, and reducing the heat is an design aim in transformers because heat, like all energy, costs money. Heat losses can be reduced in a transformer by using thicker copper wire in the windings and a thicker iron magnetic core. Obviously there is an optimum somewhere in the middle that transformer designers aim for.
What are the advantages of shell type transformers?
this type of transformer used special low loss steel to minimize eddy current losses and reduced leakage flux.
What grade copper used in rewinding transformers?
Copper with a purity of 99,99 %.

How do you calculate copper in dc motor?
Copper is not something that is calculated. The amount of copper might be, or copper losses / load losses, might be, but "copper" is not calculated.
Where does copper losses in dc machines?
Copper losses are also referred to as I^2 R losses. Copper loss is due to heating due to the current passing through the copper windings.
Is this statement true or false the maximuim efficiency of transformer is occured when iron losses is equal to full load copper losses?
Copper losses are directly related to loading of the transformer. Iron (core) losses are a result of magnetizing of the core of the transformer, and are relatively constant from no load to full load. With this in mind, it should be clear that the above statement is false. Maximum efficiency results with low core losses, and low copper losses. Copper losses cannot be helped, so it is important to minimize core losses to increase the efficiency of a transformer.AnswerYes, it is perfectly correct -well, with the proviso that transformers normally operate somewhat below full load and, so, are designed to achieve maximum efficiency somewhat below full load. A transformer's maximum efficiency does indeed occur when the copper losses and iron losses are equal. Unfortunately, the mathematical proof of this is too complicated to reproduce here, I suggest that you check out any reputable electrical engineering textbook.
Are transformers 100 percent efficient?
No because it will lose electron by core losses and winding losses
Explain the power flow diagram of induction motor?
The input power, Pin, is reduced by different loss sources in the system. These reductions are the difference between input power & output power. The losses are: PSCL: Stator copper losses, or I2R losses Pcore: Core losses PRCL: Rotor copper losses PF&W: Friction & windage losses Pmisc: miscellaneous losses All of these losses reduce the input power. The output power is the input power minus all of the losses. Pout = Pin - PSCL - Pcore - PRCL - PF&W - Pmisc
