Q:Can braided wire be used in a transformer?
You probably shouldn't. It might work if the demand on the secondary isn't too great, but solid wire will give you much better results due to having a bigger core.
Q:What is the difference between AC transformers and DC transformers?
DC transformer to change the voltage first to use the electronic components of the DC current into alternating current, and then transform the voltage with the transformer. This device is called the inverter.
Q:Transformer Lightning
Transformer by lightning over-voltage damage, usually the primary coil over-voltage burned one is short-circuit two open. Most of which is caused by the line called the induction mine (lightning) instantaneous damage, the shell (surface) no burn traces. Unless it is just in the transformer over the formation of direct lightning damage effect.       Transformer lightning is the most vulnerable to the transformer insulation problem, in fact, the structure of the transformer, insulation is a particularly important assessment factor. Transformer insulation damage, the other performance will be affected, including: three-phase voltage is not balanced, no load and load test pass. Detection method is usually: first with a shake table measured insulation resistance, in the measurement of the winding resistance, and finally can be hanging core to do no load test. You can gradually know what part of the lightning damage!
Q:Power is generated at genaration station with 33kv,then by using step up transformer the voltage raises to?
Gawd I don't know where people go to school to make up rubbish about the power being too high for use in homes. Just get a few facts and make the rest up. Ok When electricity is generated in a central power station the electricity needs to be transmitted many miles. The most efficient way of doing this is to use as high a voltage as possible. So at the power station a transformer is used to convert the generated voltage into a high voltage for transmission. When the electricity arrives at the destination it is transformed back down to whatever voltage the end user requires. The reason for using the high transmission voltage is to reduce resistive losses in the cables. I'll give an example Suppose we need to go 100 miles and have a resistive load of 1 ohm/mile We need to deliver 1MW down to the end of the line and the end voltage required is 100V We'll ignore the voltage drop for the example, but you can do homework to take it into account. If we transmit at 100 volts then applying W VI we need I 10^6/10^2 10^4 amps We have 10 ohms in the transmission path so resistive losses are I^2 . R (10^4)^2 . 10 10^9 Watts That is one heck of a loss! Now, if we transmit as 100kV 10^5V then our current is now 10^6/10^5 10 amps Applying I^2 . R for our resistive losses we now get 10^2 . 10 10^3 watts You can see the VAST difference that stepping up the voltage for transmission does now for the transmission loss.
Q:What are the malfunctions and abnormal operation of the transformer?
working principle: Transformer is the use of electromagnetic induction principle made of static appliances. When the transformer's original coil connected to the AC power supply, the core will produce alternating magnetic flux, alternating magnetic flux with φ said. The original, the secondary coil φ is the same, φ is also a simple harmonic function, the table for the φ = φmsinωt. By Faraday's law of electromagnetic induction, we can see that the induced electromotive force in the original and secondary coils is e1 = -N1dφ / dt, e2 = -N2dφ / dt. Where N1, N2 is the original, the number of turns of the secondary coil. U1 = j1n1, U2 = E2 = -jN2ωΦ, and the complex value is U1 = -I1 = jN1ωΦ, U2 = E2 = -jN2ωΦ, and the complex value is U1 = Let k = N1 / N2, said the variable ratio of the transformer. U1 / U2 = -N1 / N2 = -k, that is, the ratio of the original value of the transformer and the secondary coil voltage, is equal to its turns ratio and the difference between the original and the secondary coil voltage is π. And then come to: U1 / U2 = N1 / N2 In the case of no-load current, I1 / I2 = -N2 / N1, that is, the original and secondary coil current RMS value is inversely proportional to the number of turns, and the phase difference π. And then available I1 / I2 = N2 / N1 Ideal transformer original, vice coil power equal P1 = P2. Indicating that the ideal transformer itself without power loss. The actual transformer always has the loss, its efficiency is η = P2 / P1. Power transformers are highly efficient and up to 90%.

Q:Transformer and the middle of what is the difference
In the week is the IF transformer or inductance coil, is a fixed resonant circuit with a transformer, the resonant circuit can be fine-tuning within a certain range, so that access to the circuit can achieve a stable resonant frequency.
Q:three phase transformers pole mounted.?
In order to have a neutral in a delta connected , 3-phase transformer bank, the secondary of the system must be connected in wye or star configuration. The neutral point is grounded in order to offer some protection in the event one of the hot leads is connected to some part of a device housing where you can touch the device. Electrical codes require electrical equipment to be grounded. If the hot wire does touch the chassis of a grounded piece of electrical equipment, the current will flow back to the transformers, causing the circuit breaker feeding the equipment to trip. This removes the danger to anyone touching the equipment. The reason there is no current flow in the ground under normal operation, is there is no connection from a hot lead to ground. There must exist a complete circuit in order for current to flow, TexMav
Q:Taiwan, Taiwan, the concept of transformer
Metering points are generally placed on the two sides of the equipment for property rights demarcation point. Some "real production boundaries" are not suitable for loading tables, the measurement points can be located in the substation, if the measurement point and production to the demarcation point is different, the asset owner should bear the loss of their own property equipment. For the substation of the various routes, the measurement point is located in the various routes on the outlet. Transformer two transformers run parallel to the situation is very common. Parallel operation can make the power quality better, and better play the potential of equipment and so on.
Q:what feeds a transformer?
Hi pal! A transformer is a device which converts electrical energy. just remember that. now we know energy is E VI.t right? Now a transformer has two ends. one is the primary winding and the other is the secondary winding. winding means wound wires ;ole am inductance wire. the two of them are connected by a metallic core through which magnetic flux flows linking the two windings. Since energy is constant Voltage of primary x Current in primary Voltage in secondary x Current is secondary Now, since the number of turns of the 2 winding are different, thus the flux linkages are different i.e. N x phi so induced emf by faraday's law is different. so if secondary number of turns is suppose 10 and primary is 1000 then if voltage in primary is 1000V secondary is 10V this is how it steps down. so the transformer is FED by a high or low voltage source via busbars. this is as briefly as i can explain without boring ya!! :)
