- Q: does anybody know what Transformers 2: Revenge of the Fallen is going to be about? Like what is the whole plot, or storyline?
- I think its again about the cube
- Q: I bought my first ever Transformers toys which are the movie line, Ironhide and Barricade. However it is noted on the side of the box classes name; Voyager and Deluxe. What is the difference between both? I've search around the internet but none has given definitive description about it. All I know is that there is Deluxe, Voyager, and Leader class, and some more lower grades.Does the classes defines scale, size and complexity of the transformation?
- Transformers Leader Class
- Q: The book said the main transformer power failure operation should first stop the load side after the power side, is to prevent the transformer in the case of multi-power reverse charging. What is the transformer anti-charging here? What's wrong?
- Here to step-down transformer as an example: The forward power supply is powered by the high side of the transformer to the low side of the transformer, and the "reverse charge" is powered by the low voltage side of the transformer to the high side. When the main transformer power failure operation, we must first load side, that is, first stop low side, after the power side, that is, after the high pressure side; If there are two main transformer running side by side (or other means of multiple power), when one of the main transformer power failure, if the first stop high-voltage switch, then low-voltage switch has not been disconnected, will make another master Variable power through the low-voltage switch back to the transformer power supply, resulting in transformer back-off situation; this situation not only failed to power transformer, but also increased the impact of a transformer, when there is over-voltage, etc., may cause resonance hazards Equipment safety.
- Q: Current and Potential transformers both are actually Instrument transformers, which step down or lower down the values of current and voltages for measuring purposes.But I have heard of that both CT and PT specifically are used for stepping up current and voltages at some point of transmission system.if this is correct then can anyone tell where they are used?If not then there are step up transformers for similar uses but my question is why they are not called as CT's or PT's.
- The usual application of CTs and VTs is to provide isolation between the power system and instrumentation and/or protection equipment. And in this instance, the transformation is usually to reduce the magnitude of the voltage or current that is being measured. There occasionally are instances in which it is necessary to increase the magnitude of voltage or current. In most instances these situations involve relatively minor adjustments in the magnitude of voltage or current and take place in the CT or VT secondary. The transformers that are used to make these adjustments are typically called 'auxiliary' CTs or VTs. There are a few very specialized situations in which CTs or VTs are used to couple a signal into the power system itself. One example of this is where a high-frequency signal is superimposed onto the power system to establish a control communications channel. So-called 'power line carrier' signals are usually in the kHz range, and are typically coupled into the system via VTs - most often, capacitive VTs rather than inductive VTs.
- Q: What are the malfunctions and abnormal operation of the transformer? What is the difference between them and the line?
- 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: I know there has been plenty of Transformers anime over the years, but is there any Transformers manga?
- I don't know but that'd be sweet!
- Q: A lot of people have been discussing the new transformers film transformers dark of the moon-but how does transformers dark of the moon compare to transformers the movie 1986?For those who have seen all three of michal bays transformers films- and Transformers the movie 1986-which do prefer the new transformers movies or transformers the movie 1986?and more Important why?
- The 1986 version has better acting on the part of the voice actors, more caring tragedy, more likable Transformers, very atmospheric, and one of the most tragic death's in the history of robot-kind. The first Transformers movie was stupid but fun. The acting in it was okay, the story was incompetent in the fact that they did not explain as much as they could have, bitchy lead actors, and a pretty epic final battle scene. The second Transformers movie is god awful. It is racist, the story is copied from the first movie, the acting is horrid, the characters are bloated bitches that yell all the time, a horrid villain(s), an overactively preachy Optimus Prime, a horrid Optimus death by unknown Decepticon, Transformer balls, bad dirty jokes, Shi Labeouf in robot heaven, Shi Labeouf having a near seizure, Shi Labeouf's mom gets high, and one of the longest unneeded battle scenes in movie history. The third Transformers movie is a step above god awful, racist towards Asians, the story is copied from the first two, the acting is still horrid, Shi Labeouf is self obsessed, Shi Labeouf is mean (he kicked Bumblebee), the Decepticons are cooler but the Autobots are the same, Optimus is still overactively preachy, a blinking camera during the final fight, a horrid Megatron death, a decent twist with Sentinel Prime, bad dirty jokes, Bumblebee getting tickled, a better and prettier actress than Megan Fox, and one of the worst guest appearances in movie history (Leonard Nimoy). C Y I like the old one better. Which do you like better? Also the new Harry Potter has a 100% from all critics.
- Q: I want to multiply current 10times for a second or two. So, is there any easy way to do that without using a high power transformer?Thanx.!
- Current from what kind of source, into what kind of load? Does the load take AC or DC?? What voltage does it need?? Why do you have to multiply the current? You can get clever with things like bucking switcher supplies to take 120 volts in and get 12 volts out at about 10x the current, but if your load isn't DC it doesn't help you. Edit:? 30 A @ 8 V isn't much, just 240 watts.? You can probably get this out of an old computer power supply; just re-wind (or add an extra winding in series with) the 5 volt winding on the toroid transformer to get 8 volts.? You may have to get fancy to get it to stay on (lots of the newer supplies want to be loaded, and want special signals to run) but with common supplies putting out 400 watts and more you should have no trouble.? The only issue is that you won't get 50 or 60 Hz, but since you didn't say your load has any particular frequency requirement I'll offer this as a possibility.
- Q: A liter of transformer oil how much jin
- The main role of transformer oil: (1) insulation: transformer oil has much higher than the air insulation strength. Insulation material immersed in oil, not only can improve the insulation strength, but also from the erosion of moisture. (2) heat dissipation: transformer oil specific heat, often used as coolant. Transformers run the heat generated close to the core and the winding of the oil heat up and down, through the oil up and down convection, heat dissipated through the radiator to ensure the normal operation of the transformer.
- Q: 1- the properties of electrical transformers . #92;2-their uses . #92;3-their applications.
- 1 - Transformers step-up or step-down voltage in a closed electrical circuit. 2 - Power companies send electricity at over 500,000 volts through power lines. They use transformers to convert their power to this level and a second set which lower the voltage for home/office use. 3 - Allowing you to use electricity at different voltage levels for different applications.
