Q: Transformers are divided into several. What is the role of each? To be specific!: Transformer is the instrument that regulates voltage! Transformers can be classified according to their operating frequency, use and core shape. (1) Classification by operating frequency Transformers according to the operating frequency can be divided into high-frequency transformers, IF transformers and low-frequency transformers.

Q: 500KW load should be installed how much transformer?: Mainly to see what the load, if it is home lighting electricity, according to the 0.9 power factor and 20% of the margin, you need to be equipped with 500 / 0.9 / 0.8 = 694.4, you can take 750 kilovolt capacity can be. (Consider the future expansion of another operator), if it is with the motor and other load-based, due to power factor and start the current reasons, at least 900 kVA more appropriate. If the drive is more than 200 kilowatts, the starting current is very large, you need to put a larger margin or the motor using the buck mode (increase the investment cost).

Q: I have a US Navy Plate and Filament Transformer Manufactured by Hudson American Corporation.This monster weighs 14.5lbs, and is in a sealed steel casing.There are 16 unlabeled terminals, and I'm working to identify those.It does however have the current and voltage labelings for the primary and secondaryPrimary : 110/115/120v AC (Since there are 16 taps, I'm guessing that these are separate primaries)Secondary 1:360-0-360 200MA DCSecondary 2: 6.6v 10A CTSecondary 3: 12.6V 3ASecondary 4: 5.25V 3AI'm set on using a solid state rectifier circuit so i don't need the 5.25V Line, or the 12.6V line.Could I somehow do something to get extra current on the B+ line (S1 windings) with these unused secondaries?I want 4x 6550/kt88, so the extra plate current would be great to have around.: You can probably draw a bit more from the 720 volt winding if you don't use some of the other windings. Also if you use SS rectifiers, you will get more DC voltage than normal, about 490-500 volts, so the extra drop you would get at higher current may be ok. Or you could use a choke input filter instead of a cap input to get about 350 volts, enough to operate KT88's, and get more current. Watch out for over heating. edit: Electrolytic caps would be a lot smaller than the ones you have. The two chokes in parallel could be used as a choke input filter. Exactly what voltage and current do you need?

Q: Can someone all the Transformers stuff? I mean, I see a lot of stuff about 'G1' and 'G2' and I think I heard something about their being TONS and TONS of different storylines for it.Will someone name each storyline, and what G1 and G2 is, and please tell me the official canon usage?: I'd like someone to explain these dumb Action movies to me too!!! :

Q: how low voltage smelting transformer can be modified to a higher voltage to be used in ferronickel production: You need to provide more information about the original use of the transformer. Nickel smelting is a very specialized application that calls for a 'submerged arc'. Basically, the arc is fairly short and will essentially be submerged in a layer of slag on top of the molten material. It is a semi-continuous process in that periodically, some of molten nickel is poured off. The stream of molten nickel is blasted with water that causes the nickel to solidify into small pellets. Steel melting furnaces, by contrast, involve a much longer arc. The slag layer in the furnace is much thinner, and much of the arc is above the slag. It is a batch process in that once the 'campaign' has been completed, the entire melt is 'tapped' - poured into a tundish either to be cast into ingots or to feed a continuous casting process to make billets, slabs or even plates. There are other smelting processes for other materials - for example, silicon is produced via a smelting process. I would guess that if the voltage requirements of the nickel smelting process are different from the requirements of the original utilization, then it would be necessary that the transformer be redesigned and rewound - something that I would not expect to be very practical.

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: I have a 25 volt 2 amp transformer from radioshack and a non push dimmer from walmart. The dimmer has two black wires and one green. The transformer has on one side two yellows and a black and on the other side two blacks. I need to know how to hook the dimmer up to an outlet then how to wire it to the transformer.: The number of wires on the transformer don't match with the stated voltages. The two blacks are probably the 120 volts input (assuming this is the US) but the 3 wires on the secondary imply you have a center-tap secondary, possibly 25 volts center tapped at 2 amps. I'm also assuming that the hot wire is sized to operate on 25 volts. The transformer should come with some sort of labels for the wires, if not take it back and get one that does. Once you get the transformer straightened out, here is a wiring list. AC hot from line cord black wire to one side of a 1 amp fuse holder AC neutral from line cord white wire to one of the line connections of the transformer AC ground from line cord green wire to transformer case and to case of dimmer (green) and to metal case this is all mounted in. Other side of fuse holder to one of black wires of dimmer Other black wire from dimmer to the second of the line connections of the transformer One of secondary wires on transformer to one side of the hot wire Other secondary wire on transformer to other side of the hot wire Tie the center tap of the secondary, if there is one, to ground. If not, tie one of the secondary wires to ground. You will note that I included a small 1 amp fuse. You can get a small metal box to mount this stuff in, or a electrical junction box. The latter is better as it has punchouts for cable in and out. Be sure to clamp the wires where they enter and leave the box.

Q: I fried a transformer in my lathe. I went to the electrical supply near my house and the got me a new transformer and said it will work. The old transformer is 3 times bigger. they are both 100VA. the voltage on the original is 230v in and 100v out. It powers the on/off switches for the forward/ reverse micro switches. from the micro switch it powers the magnetic puill in for the contactors. The contactor say 100V.will using a 110v transformer cause and problems or issues?Should I return the one I purchased and order a 100V ?I have work piled up and waiting and really need this lathe operational ASAP.Thank You in advance for any information.Earle: Since they are both 100 VA units, capacity seems to be OK. The voltage however should be checked further. For example, you say the unit you removed was 230 volts in and 100 volts out. This is a ratio of 230/100 2.3 to 1. Thus if you have 230 volts on the high side of the transformer, you will get 100 volts on the low side of the transformer. If the new unit you purchased is 230 volts in and 110 volts out then the ratio is 230/110 2.09 to one. So if you have 230 volts on the high side you get 110 volts on the low side. However, I suspect the new transformer is rated as 240 volts high side and 110 volts low side for a ratio of 240/110 2.18 to one. So f the input is 230 volts you will get 105.4 volts on the output. Thus the increase of the output may only be 5 volts, not 10 volts. Bottom line is that the new transformer will work just fine either way. Over-voltages due to switching surges may be ignored as most designs have already taken that into account with voltage variations of +/- 10% normally. Hope this helps, Newton1Law

Q: I have an AC to DC transformer I got out of a radio. I removed the rectifing (spelling?) circuit. So why is it that the transformer still only responds to AC input and not DC? I basically want a transformer that can take low voltage (aroung 6-12v DC) and step it up to 400VDC. Any suggestions or help?: The way a transformer works is by magnetic fields in one side (the primary) causing current flow in the transformer's other side (the secondary). For a magnetic field to generate a current in a coil of wire, it must be moving. This could be physically moving like in a generator or a field that is expanding and collapsing like that cause by an alternating current. Only alternating currents can cause a voltage increase in a transformer. The ratio of voltage in to voltage out is equal to the ratio of turns in the transformer coils (primary, secondary). To go from 10 VAC to 400 VAC requires 40 times as many coil turns in the secondary as the primary. But, the first thing you have to do is convert the 10 VDC to 10VAC. To do that you'll need and ocillator circuit. (Also called an inverter.) Wikipedia has more information and diagrams.

Q: I bought a Neon Sign Transformer over OKorder and for a while it worked great. I used it to power a Jacobs Ladder (I wired the transformer straight to the Jacobs ladder). However, now the transformer will turn on the jacobs ladder but after a couple of seconds it will shut off and sometimes make a buzzing noise. What is wrong with it and how can I fix it?: You have 2 problems there. 1. Voltage; 2. Frequency. In this case, both are against you. NZ has 50Hz mains frequency at 240V. If you are really lucky, the transformer will have dual windings on the primary, or a 220/240V. tap. If you don't know what you are doing, consult an electrician or electronics tech. to have them check whether it is dual voltage, and change it. The frequency difference can mean a little less efficiency, the transformer may get a little warmer in operation. But it should be fine. You only other options are to replace the transformer (get one for dual voltages?), or use a 240/110V stepdown transformer ahead of it. The stepdown transformer must have a sufficient power rating for the job.
