- Q: Hi Guys.I'm a college a student who is wondering which tablet to buy. I really can't decide.I want to have a good tablet that I can type and hand write on it. A Tablet that can play 720p and 1080p mkv files. A Tablet that is good for pdf reading. This is all I want. The problem is these two tablets are really good. The New Ipad is running IOS 5 while Transformer Infinity is running ICS.I haven't had tablet before so I have no experience, please I'm open to any advice.
- Hello, I'm brazilian and a student like you, In my opinion I guess you have to buy a transformer infinity Why? Because it's really better than the new iPad in many things. ? You will can write in the dock, but this dock is diferent of anyother of iPad docks 'cause it give to you an aditional batery life ? The display to is better than the iPad 'cause it's better to see any video on youtube or movies 'cause the display format. HD vs 4:3. I know that the iPad got a retina display, but it can't change the fact of 4:3 ? You're a student, so a device to you have to facility your life. Try to use a pen drive or a microSD card in an iPad, you can't. But in a transformer you will to use its. It will make a diference 'cause its faster than conect you device on a PC and use the iTunes. I could say many other things I never use a tablet too, and I want to buy one, I will buy the Infinity (when it comes to the Brazil, what I guess that happen in 2064) 'cause it's better to me. God bless you. PS: Sorry by my english, I really don't know speak english, just the very basic
- Q: 800kw motor how much transformer
- Transformer power factor is generally 0.8 (also 0.7), then the total power transformer = 800 / 0.8 = 1000KW. According to the "Power Engineering Design Manual", the transformer capacity, for a simple load of a single transformer, the load rate is generally about 85%, so the above example, the transformer capacity = 1000/85% = 1176KVA, select 1176KVA above capacity transformer. If it is a single motor, due to the starting current, even if the measures taken, but also increase the corresponding transformer capacity. If the three-phase imbalance, but also a corresponding increase in transformer capacity.
- Q: What is the reason why the dry transformer is loud
- 500kva below the dry-type transformer noise 56 to 58 dB or so, 630kva above 62 to 65 dB or so! This is our factory data. The dry-type transformer sound is great. Big like cattle called the same, because the core is loose!
- Q: Can a transformer having a given VA rating at 50Hz handle more power at a higher frequency, say, 300Hz or 400Hz?I want to build an inverter to run an 11 watt compact fluorescent lamp. Since these devices rectify the supply directly, there does not seem to be any good reason to feed the lamp with 50Hz.If my understanding is correct, the core has to be able to store up to one half-cycle's worth of energy in the magnetic field (which will then be released out of the secondary winding in the form of electricity) to avoid going into saturation and overheating. So at twice the frequency, it should be possible to push twice as much power through for the shorter half-period without saturating the core. (Actually, probably a little less than twice as much, as there will be more resistive heating; but transformer wire is often slightly thicker than it really needs to be, just because it's less likely to break in the winding machine.)So can I over-run a transformer this way, or is there some gotcha that I've missed?
- The equation V 4.44fNaB determines what is required for a transformer to avoid saturation. V is the voltage, f is the frequency, N is the number of turns of wire in the winding, a is the area of the core, and B is the peak magnetic flux density. The transformer has presumably been designed so that the peak flux density is as high as it can be without saturating the core. For an existing transformer, V/f a constant. If you increase f, you can increase V so that V/f remains constant. However, the hysteresis losses increase in proportion to the frequency increase and the eddy current losses increase in proportion to frequency squared. In addition, skin effect will increase the copper losses at higher frequencies. Reducing the copper losses by reducing the current would compensate for the skin effect. Reducing the copper losses would tend to compensate for the increased iron losses, but it is hard to say how much a cooler coil will compensate for a hotter core.
- Q: Distribution transformer
- The low voltage winding is placed closer to the core because the high voltage winding requires more space due to its MV insulation. If designers put the LV winding outside the MV winding, the tank would be larger because the _MV_ winding size would be about the same size. More insulating oil would be required, and the leakage reactance would be significantly higher. Remember, higher leakage reactance means that the voltage regulation (more aptly voltage drop) under load will be higher, which is not desirable. And, of course, a larger tank and more oil make for a more expensive transformer. Edit: MV winding is about the same size for either configuration, due mainly to insulation requirements.
- Q: The specification states that the 35KV substation is capable of obtaining the power supply after the main transformer is powered down. Therefore, in this case, the transformer used should be connected to the power supply side of the circuit breaker. My question is that the main transformer which, the main transformer is not connected to the power supply side of the circuit breaker?
- 1, the so-called main transformer or (plant) with transformers are transformers, but according to their use of different names. The so-called main transformer: generally in the power plant or substation are so called, its function is for the system through the required level of power transformer; the so-called (factory) with the transformer is inside (power plant interior) Electrical equipment to provide power transformer. 2, the (plant) with the transformer power supply connected to the main transformer on the same bus, and some received another external power supply, so that when the main transformer can be maintained when the maintenance (plant) to continue to have power!
- Q: i need a transformers costume that can transform into a car, truck, etc i need to buy it for this kid for his birthday. medium size please. and he wants it as optimus prime.he wants it to look good and if he doesn't like it, well hes gonna be sad
- wrap urself in tin-foil. lol
- Q: LED non-isolated drive transformer (two windings) calculation method
- T cycle, f frequency D minimum duty cycle Vout output voltage Vin input voltage Ton magnetizing time
- Q: I have a 34kv/380/500KVA transformer and it loads a pump of 450HP/2200V. Starting current reaches up to 1700 amps for around 3-4 seconds using a soft starter. The rated capacity of the transformer is 700amps and the pump running current is 689 amps.Any calculations to prove that the transformer is enough to provide the application would be a help.thanks.
- Damn, had to read the question before I realized it has NOTHING to do with Optimus Prime or Megatron. (*laughing*)
- Q: Power transformer primary current and secondary current
- Do not know what the specific content of the question you ask? If the relationship between the variable and the ratio, then the secondary current and primary current ratio of the transformer for a second and second turns ratio, the need for specific problems.
