Q:Transformer issues?
Damn, had to read the question before I realized it has NOTHING to do with Optimus Prime or Megatron. (*laughing*)
Q:How much W?
1. And your material related. If the good material, high frequency loss is relatively small. You can do 15W. For example, 200KHZ switching frequency. 2. If you are on the general market, the maximum control in the following 10W. Switching frequency 50KHZ.
Q:What is the meaning of the transformer capacity unit KVA?
KVA for apparent power, its size and power factor! For example: power factor cosΦ = 0.8 active power P = 1Kw Then tgΦ = 0.75, so the square of the apparent power S = the square of P + the square of P * tgΦ When the power factor is 1, 1KVA = 1KW
Q:why doesn't the emf induced in the primary of a transformer does not cancel out with the supply voltage?
Leaving aside the double negative, the problem is your use of cancel - what do you expect - that it will go back to the generator and kill it? The transformer produces an output voltage which tries to do work against a resistance or inductance - the work it does produces a back EMF which the supply voltage works against so the generator has to do work. If there were no EMF in the primary, it would behave like a short circuit and blow the circuit - which is does in a small scale in the starting surge that you have to allow for when turning on equipment.
Q:Physics Question about transformers!!?
A. Zero, since dc current does not have a varying magnetis field. B. 550/120 20/ X 4.3636volts Ne /E p Ns / E s C.4.3636v / 14 .311 a. Es / R t A s D. .011 amp if the transformer is 100% efficient
Q:Transformer depreciation period is not specified?
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric transformers, rectifier transformers.
Q:Lights in house dimmering / flickering after lightning hit transformer?
When lightening strikes power lines or transformers it causes a power surge, without the proper precautions (surge arrestor) this can cause damage to electronics and other misc. electrical items including the transformer, the service, the meter, and the panel which cant be protected by a surge arrestor, First things first, you need to contact the power company and let them know that one of there transformers was hit by lightening, next you will need to know who else is powered by that transformer if any body else is. some places have a transformer on each home, depending on where you liveif somebody else shares the transformer follow the lines to there house and ask them if they have the same probIf so its the power company's problem and they will likely replace it. If its shared and the other person does not have the same problem or If you are on the only one on the transformer then you will need to hire an electrician to inspect for damage and repairs.
Q:help with transformer problem.?
You question does not make sense. First issue: You want to calculate the no load voltage? At the secondary? But you specify a power factor? The only possible interpretation that can be drawn from a specification of power factor is that the transformer is under load. Second issue: You specific primary and secondary winding resistance and inductance. The problem is to calculate open circuit (no load) secondary voltage. But the specification says nothing about the core. If the transformer is open circuited, there is no secondary current, and therefore no voltage drop in the secondary winding resistance and reactance. And the specification says nothing about the core, the one must presume that there is no core loss. In the absence of core loss, and at no load, then there is no primary current, and therefore no voltage drop in the primary winding resistance and reactance. Third issue: what do you mean by a 10?
Q:10KV distribution transformer how to calculate the tap voltage
If the gear is expressed as 10 ± 2 × 2.5%, the transformer is 5 files, each level gear can be adjusted 10000 × 2.5% = 250V, and so on.
Q:line output transformer replacement?
If you have an identical replacement transformer there shouldn't be a need to adjust anything to start. As to cutting wires to remove the old transformer to replace the new one, I suggest you make yourself a chart of any color coding of the wires or tagging them so there is no error as to what to connect to what on the new transformer. I personally would replace the transformer as the manufacturer installed the original one. As for discharging, use a 10K ohm resistor with one side to ground and the other side of the resistor to the components you want to discharge. I don't advise just grounding direct. Good luck and be careful.
