Q: i bought transformers a few months ago, and i finally watched it last night.my nephew watched it and i guess got something on the dvd.i was at the ending where they rolled bumblee in on the truck and the cube was destroyed and all that and optimus prime was saying they lost a great ----- i can't remember extactly what he said.anyway, right after that, the cd skipped and went do directly to the credits.what did i miss?: I think he says they lost a great warrior. The Autobots stay on Earth and will try to live peacefully among humans. Sam and Michaela end up together. They also leave it open for a sequel because one of the bad robots (the tiny one that tried to break into the government's system before the Australian girl caught him) escapes back to his home planet. Presumably to bring back more of the bad Transformers. I have read that they plan to begin shooting the sequel soon - will possibly be out in the summer of 2010.

Q: Want to use in the air compressor, I do not know it?: Transformer oil can not be lubricating oil, because the main role of transformer oil insulation is not lubrication. 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. (3) arc suppression effect: In the oil circuit breaker and transformer on-load regulator switch, the contact will produce an arc switch. As the transformer oil thermal conductivity is good, and in the arc under the action of high temperature can touch a lot of gas, resulting in greater pressure, thereby enhancing the dielectric arc performance, so that the arc quickly extinguished.

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: I understand that a 70-volt transformer is used in a commercial environment, to connect several 70-volt speakers to a 70-volt amplifier. But why does a 70-volt transformer have all of those different colored wires coming from it? What do they connect to, and what are they for? How would I connect a 70-volt transformer to an amplifier, and where I connect the cable that goes to the speakers? Please explain this to me in an easy to understand way, because I was curious about this for a long time.: The okorder

Q: How to make a current transformer more linear? Except change the core.Thank you!: There could be eddy currents in a poorly designed transformer, yet sensible transformer cores are produced from laminated iron so as that the present can't circulate around the middle. you do no longer choose the middle to appear as if a shorted turn on the transformer. inspite of out eddy cutting-edge loss, there nonetheless is capability loss interior the middle that equals the part of the B-H loop according to cycle of ability.

Q: Hope to engage in the transformer predecessors to answer. I hope you help me introduce a little more recommended information better: GB GB / T6451 made a detailed provision, the latest version of the 2008 revision. (Boost, buck), three laps without load (boost, buck), autotransformed (boost, buck), the two-lane, There are several types of auto-load (boost, buck) and so on, there are about 31.5,40,50,63,90,120,150,180,240,370,400 MVA several grades, but corresponding to different types of transformers, Capacity level is slightly different, do not know what type of capacity you ask the range?

Q: Exactly what is the storyline of the Transformers. As far back as I know, there were two brother, Unicron and Primus who fought each other because Unicron wanted to suck up Universes. But where did these two come from? Does it even say?: I am a fan but I haven't been able to find that out myself, if you find out let me know.

Q: I have a power transformer and i forget where it came from. It has two leads from a wall outlet plug and then goes to the main (square) casing. there are three wires that come out the other side. They are from left to right, red,white and red. I assume its a 9v ac to dc transformer but am not positive. Can someone help me? I suspect that the white wire is ground. Any help would be great.: There's no reason to assume anything, except that the primary side (with the line cord and plug) is probably intended for 115 Volts, AC. If it's a transformer (rather than a power supply) it's not AC to DC at any voltage. Transformers convert AC to AC. With those colors on the secondary, there's a pretty good chance it's center-tapped. Red-to-red will be twice the voltage of either red-to-white. Nothing should be grounded to the transformer case.

Q: I check the voltage between x1 and x2 I got 120v but between x1 and ground on primary I got 40v and between x2 and ground on Primary I have 50v, if I connect x2 to ground won't it short the transformer? Thank you: What you see is normal, until the transformer is grounded the voltage floats. It is the same with the power for your house, the secondary of the transformer is normally grounded at the utility transformer, and at your ground rods, and to your water lines. X2 is the normal side grounded, although this has never made sense to me. You can imagine this, connecting one end of a flashlight battery to the frame of a car does nothing, you could then attach the other end of the battery to a light bulb, and the other bulb connection to the end of the battery or the frame, it only shorts if you connect the hot to the ground if you don't connect through a correctly rated load. Edit: Yes, ground it to the ground screw that the 208v ground wire is connected to, just to be clear, 208v connections H1 and H2 should not be grounded, and either x1 OR x2 needs be grounded, normally x2, grounding the transformer connection that is not connected to fuses.

Q: Hi there.I have purchased a Stepdown Transformer so i can use a Record Cleaning Machine I am buying from the U.S.It uses a powered suction unit to clean the record.All transformers for use with American equipment have 110v output, but i think your equipment is usually 120v.in I have been told that there is nothing to worry about as 110v out on the transformer is enough to power the equipment connected to it .Our AC output in Australia is 240v but we can use any voltage from 220 to 250. Therefore 110v should be enough.can anyone clarify and tell me it should be ok.Thanks a lot in advance.: I live in New Zealand. We use 240v 50Hz mains here too. USA uses 110/115v 60Hz. There is a 10Hz voltage frequency difference as well as the voltage difference. The stepdown transformer will be rated for 110v RMS(root-mean-squared). This is a kind of average, for want of a better description. The peak voltage is 0.707 times the RMS voltage. This is the peak on one half of the sine-wave(180'), therefore the complete sine-wave mains frequency represents 1.414 times the RMS voltage.(360' sine-wave cycle) Multiply 110v by 1.414, and you will get the peak-voltage, which is the maximum that the AC voltage can swing, both in the positive and negative parts of the sine-wave. 110v example: 110 x 1.414 155, therefore, the PEAK voltage for the States is 155v AC, or thereabouts. 240v example: 240 x 1.414 339, therefore, the PEAK voltage for Aus/NZ is 339v AC, or thereabouts. All mains voltages are a measure of averages(RMS), so a 10 or so volts either side of the stated voltage, should not prove to be a problem. Provided that the stepdown transformer can supply at least a few amps of current on the secondary(the 110v side), there will be no problems at all. Technically, the 10Hz frequency difference can make a slight difference, especially if you are trying to power some sound equipment from the States, as the Australian/New Zealand 50Hz frequency will mean that the motor will run slightly slower then the designed RPM. However, in your case, I don't think it will make one iota of difference. :)
