Q: Electrical Machinery, electrical machines, transformers: A transformer steel core's remanence means that it retains a static magnetic field when power is removed. When power is then reapplied, the residual field will cause a high inrush current until the effect of the remanent magnetism is reduced, usually after a few cycles of the applied alternating current. Overcurrent protection devices such as fuses must be selected to allow this harmless inrush to pass. When a transformer is livened, the magnetizing inrush currents are estimated as multiples of the transformer's nameplate kVA. Time Current (sec) - (amps) 0.01 -- 25x 0.10 -- 12x In addition, during the normal life of a transformer you can expect hot-load and cold-load pick-up events. These are estimated as Time Current 1.00 -- 6x 10.0 -- 3x 100. -- 2x You must select transformer fusing that will not be damaged by these events. Drop me an e-mail for a more detailed explanation.

Q: 1. What does a transformer actually trasnform?2.What does a step-ip transformer step up?3. In a transformer, how does the power input to the primary coil compare with the power output of the secondary coil?: It transforms voltage and current from the values that exist at the primary to the values that exist at the secondary. 2. It steps up voltage. 3. Ideally, the input and output power would be the same, that is the product of voltage and current would be the same even though the voltages and currents are different. I practical transformers there is resistance in the wire and energy loss in the core so that the output power is slightly less than the input power. The difference appears as heat in the transformer.

Q: could i connect a flyback transformer directly to an ac power supply instead of a 555?: You can but you'll just blow up. That is if your not planning to kill yourself. What sort of a project is this. You must state specifically what is your main aim is here.

Q: I think it will. Michael Bay who doing the movie has a history of messing up classics. Godzilla is my prime example. So, what do you think? Transformers the movie: Good or Bad?: I was afraid that this movie was going to be total gay, But after watching some trailors and seeing who they got as the actor (Shea LeBue sp?) I am kinda excited about seeing it. I was never a transformers geek so I have no prier knowledge going into it or any expectations so I may have a uneducated opinion of the movie.

Q: Hi,Should i wait for the Asus Transformer Pad Infinity, or should i buy the New iPad ?Thanks,Patrick: Hardware is negligible without software. The Google.play site (Formerly the Android Market) has plenty of apps to choose from. Basically, your investment is in the simplistic ease of the New iPad or the flexibility of Android 4.x. It's really a matter of which O/S you wish to support. I calculate the iPad IPS display has 25.7% more pixels than the new Asus model. Will you even notice the difference? Not at those screen sizes. Besides, the Asus has a 16:10 Ratio for a better movie experience. Personally, I have already seen that even the new iPad can't match wits with a Tegra 3 tablet when running certain games. Comes close, though. I'm waiting with baited breath for the Asus Transformer Pad Infinity. In my opinion, so should you.

Q: I read something somewhere once about using small mains transformers as substitute speaker transformers in valve circuits.Suppose I have a 6-0-6V transformer with a 240V primary. That gives a 20:1 turns ratio. So if the secondary is putting out Vs volts at Is amps into 8 ohms, then (neglecting losses) the primary will have 20*Vs volts across it and Is/20 amps through it. But we know that Is Vs / 8; so the primary will appear to have an impedance of (20 * Vs) / (Vs / 160) 3200 3.2k ohms.Am I thinking right? Or will the presence of DC in the primary ruin everything?I'm thinking of using an ECL82 (aka 6BM8) for my first project, as that has both a triode and a pentode with separate cathodes and seems to be available still. Is this a good choice?: That's wrong

Q: given that volts x amps watts why dont they just rate a transformer by kilowatts. I havent been able to link the logic behind rating a transformer by KVA, but there must be a reason. If you think you can help me I am eager to learn and will appreciate your help.: Kilovolt Ampere

Q: Why the provisions of the maximum temperature of the provisions of the transformer 65 °?: Most big oil temperature increased load, the transformer internal fault, there is lack of oil performance security risks. So we do need to limit oil temperature and protection tripping. Small capacity (630KVA less and outdoor) often do not have the oil temperature protection. I have the original table 800KVA overload (secondary current 1500A), top oil temperature to over 90 degrees ......

Q: I am installing a humidifier. It comes with a 120vac to 24vac transformer to be installed. The transformer has a label on it that says install in electrical box only. One side of the transformer is designed to screw into an electrical box knockout and has leads coming through the middle of this for connection to the 120VAC input.Is the transformer supposed to be screwed into the electrical box on the outside or the inside. At first, I assumed inside but this would result in my connection leads being on the outside. ThanksBill: The transformer is designed to be mounted on top the 120v junction box that exists inside the furnace. In most new furnaces there should be two extra wires in said junction box, one marked EAC and one marked HUM hook the black wire from the transformer to the one marked HUM and the white wire from the transformer to the two white wires already connected together within that junction box. This will provide power to the transformer only when there is a call for heat. The low voltage wiring connections should be pretty easy to follow in the instructions. NEVER, I repeat, NEVER power the humidifier using the transformer supplying low voltage control power to the furnace, 9 times out of 10 you will overload it.

Q: How does a transformer effect amplitude modulation in an am transmitter. i would really love this to be explained from the basics as i am not so advanced in electronics. but i would really like to comprehend how this happens form the basics. thank you: The collector of the output transistor or plate of the output vacuum tube in a high power AM transmitter has DC voltage and an audio signal applied to it. The audio signal causes the the transistor/ tube to create AM. The AM radio frequency is shunted off to a tank circuit and then coupled to the antenna. A transformer is used to couple the audio signal to the transistor's collector/ tube's plate. A high power audio signal is applied to the primary side of a transformer and the secondary of the transformer is connected in series to the DC power source to the output device. This creates a varying DC voltage to the output device which creates Amplitude Modulation.
