Q:i just got back from seeing transformers and the special effects were awesome but the storyline could have been better. I thought the girl meghan fox was so prettywho thought the same?
Well, you can call me nuts! It was so goood, I watched it FOUR times. So good, I'm thinking of going for a 5th! (4 is bad luck!). To me, Transformers just broke the barrier when it comes to making robots that interact well with humans. The awesomely human-like behaviour of the Autobots, the cool action scenes, fast but cool transformations and the god-like Optimus Prime took my breathe away! Absolutely the best movie this year. No one could ask for a better live adaptation of a cartoon, especially one that we used to love.
Q:10 (6) /0.4kv three-phase transformer what does it mean
Three-phase five-column core transformer must be used YN, yn0, yn0 connection, in the transformer must be connected into the angular connection of the fourth winding, it is not out of the beginning (the structure to do the electrical test when the lead is not This case). 5). When the transformer of different connection group is running in parallel, the general rule is that the connection group label must be the same. 6). When the distribution transformer is used in the multi-mine area, the Yzn11 connection method can be used. When the z-connection method is adopted, the impedance voltage algorithm is different from the Yyn0 connection method, and the copper consumption of the z-way winding is more. Yzn11 connection distribution transformer lightning protection performance is better. 7). Three-phase transformer with four volumes when the core frame can not be used YNy0 connection. 8). These are used for the domestic transformer connection, such as the export should be required to supply the appropriate connection and connection group label. 9). Generally in the high-voltage winding are connected with the tap-changer. Therefore, when selecting the on-load tap-changer (including the on-load tap-changer and the off-circuit tap-changer), it must be noted that the transformer connection and the on-load tap-changer (including connection, test voltage, rated current, Level voltage, voltage range, etc.). YN connected to the on-load tap-changer used on-load tap-changer, it is also important to note that the midpoint must be able to lead. ?The answer is recommended by the questioner
Q:A 8000kva transformer can bring the maximum load
P = 8000 × (60% to 80%) × 0.95 = 4560 to 6080 kW ????? Apparent power capacity is more suitable than the power factor for the load range Maximum load: Pmax = 1.2 * S = 1.2 * 8000 = 9600kW
Q:I used to live in the US but moved out to the Philippines. In the states the voltage out put is 110 but here in manila its 220. Because of this, all of my american electronics need transformers so they dont burn up or explode. Which one should I use on my TV. A Voltage Regulator (AVR) or a transformer? What in the heck is the difference anyway?
now i know .what i need to refrigirator,,a transformer right?
Q:i have a flyback transformer that i want to make a tesla coil out of and i need a diagram for the wiring configuration.
The modern flyback transformer is also used to generate the DC operating voltage for the TV set. You have a lot more wires than you need to use. You need to get a copy of the wiring from someplace like a Sears repair shop and hope you don't have a built-in high speed diode and filter cap in the same package. The last thing you need is to try to run your Tesla coil from a DC source on the primary. I believe Ramsey electronics makes a package Tesla kit that runs off a flyback. Your coil will not produce a very large brush discharge but it should be a good demonstrater which will have a safe, low current spark.
Q:Can dry transformers and distribution cabinets be placed in the same room?
Yes. Dry-type transformers are usually placed in the room with a shell, low-voltage cabinet is with the dry-type transformers together. The general practice is to flush the cabinet. And then connect the transformer with the low voltage cabinet directly in the cabinet to go. Outside can not see the connection of copper.
Q:100kVA above the transformer grounding resistance is how much
100kVA above the transformer grounding resistance should not exceed 10 Europe. 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). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:hi can anyone tell me when installing/replacing a door bell transformer when switching off power supply at main source will that make it safe to work with the connections, it keeps telling us to turn fuses off well it dont have fuses its a circuit breaker. so do we turn circuit breaker off asweel as main supply into house. may be a silly question to ask but dont wnat any trips to A nad E lol thanks guys xxx

Q:50kva transformer price
1,50kva transformer prices vary according to model prices ranging from 6000-20000 yuan.
Q:I heard somewhere that Steve Jablonsky's orchestral score to the new Transformers movie (which is fabulous!) would eventually be released on CD. Does anyone know anything about this?
Hey Emily, People don't know the difference between Soundtrack and Score. Jablonsky's score hasn't been released yet. According to Soundtrack , it's in the works and will be released soon. Who knows when. Here's my source: soundtrack /features/article/?id235 Good luck!!!
