2. General

SG10 type-this series dry-type distributing transformer has strong withstanding of thermal shock, overload capability. Beside, it has many good points such as flame-retardant, low-loss, and low partial discharge capacity, low noise, no harmful gas and no pollution. It is insensitive of humidity and dust, compacted, no crack and so it is easy to be maintained. Therefore, it is suitable for the using in the adverse circumstances of high requirement for fire protection, high degree of load fluctuation and dirty, moist, such as airport , power plant, metallurgy, hospital, skyscraper, shopping center, and residential areas and other special environments like oil, chemical industry, nuclear plant, nuke, etc.

Q: How long does it take to restart the transformer?: If the transformer is shut down for a month or on hold, the trial is stopped for more than 6 months before the commissioning? A: The transformer shut down for a month, before the resumption of power transmission should be measured insulation resistance, qualified to be put into operation.Post or outage for more than 6 months of the transformer, should be done before the insulation resistance and insulation oil pressure test Dry and cold areas of irrigation and drainage dedicated transformer, the suspension period may be appropriate to extend, but not more than 8 months

Q: I'd recommend a big Transformers fan for this please. So I have a Transformers series that I'm working on for fun, and I want an awesome name for it. It has Unicron in it and the Autobots and Decepticons team up to take him down. A name for that part is Cybertron Alliance. But I also need a name for story with events that take place before that, when the Bots and Cons were at war. Please help!: Huge transformers fan? you got me ;D Sounds pretty cool. can I read it when youre done? The Ultimate Alliance Rise of Unicron it would be great if you could add more details so I could think of more names : just give a rough outline perhaps?

Q: How can the locations and polarity of the windings be tested on the various legs of a core when it has 2 open(circuited) three pahse windings (III and iii)?what measurements are required , assuming that the transformer is so enclosed that only the 12 winding terminals are visible?Ohmmeter , voltmeters , a single phase voltage supply are available.: It sounds like you have a three phase transformer. In the cover plate there normally is a drawing to guide you on what you want to do. Most trans formers can have input voltages of 440 volts in to 240 ouput. but some can provide 115 volts on the output if wired correctly. Any transfomer compnay website provide wiring drawings that pretty match everyones transformers. Contact the manufacturer of the transformer for instructions.

Q: Do you think if I asked this. which I am maybe people will pick Transformers because more Americans watch Trans instead of Gundam but if people watched both, would they still pick Transformers?: Dude, Gundam. Always. Transformers Armada was funny but the movies and tv shows never really seemed that good. Its just because it has megan fox in the movie. That's why so many people think Transformers are cool. Gundam is the ultimate. Especially Gundam Seed and Wing.

Q: I know that in a step-down transformer if I have 10 turns on the primary coil and 5 turns on the secondary coil that the voltage gets reduced by half and the current gets doubled, but is there any other significance?: The magnetic flux generated by the current is proportional to the number of turns of the coil.

Q: There are lighting transformers, tires and disassembling machine transformers, there is an electromagnetic starter, the tire changer transformer will always burn ah, are used 380V transformer, I have measured the next, when the transformer transformer measurement 391V, electromagnetic Starter average is 396V, nothing to have, has been used very well. But the tire disassembly machine transformer to die, the average voltage of 396V, installed up a few seconds to very hot, but why the other two no matter? Put away Tire disassembling machine Transformer I alone load the air switch voltage ah, 396V, only more than 10 V, the other transformers are not any problems If there is no problem with the secondary side, the voltage reaches the number of volts, the transformer will quickly become hot PS: 396V I was in the 380V where no-load test ah, more than 10 volts are not ah: This voltage is normal, mainly due to the secondary load is too large, measured under the secondary current. For large capacity transformer can be. No load is not, it can only show that the quality of the transformer there are serious problems, another regular manufacturers with

Q: I have a transformer of 12060 Volts and a transformer of 15000 Volts, both neon-sign types; if I wired them together, would it amplify the output voltage or have a catastrophic effect that would end the world as we know it?But really, can I wire them together for an added effect of some kind?Thanks.: I would not recommend it.

Q: If I have a step down transformer, the voltage in the second coil decreases. From conservation of energy (Power of firstpower of second coil) the powers are equal. But if PU*I and the voltage decreases, does the second coil have a higher current in order to maintain its power?: A transformer makes use of Faraday's law and the ferromagnetic properties of an iron core to efficiently raise or lower AC voltages. It of course cannot increase power so that if the voltage is raised, the current is proportionally lowered and vice versa. hyperphysics.phy-astr.gsu.edu/hba Goodbye

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: I really want the transformer but if i buy it i have to wait for shipping. But on the other hand if i buy either one i have to wait 2 weeks for the other.: killzone 2!!! Is the best FPS game rigth now
