- Q: 1000KVA transformer power loss is how much
- Transformer no-load plus stray loss is fixed, usually 6% of the total capacity, load loss that is copper loss, according to the load power, and power factor calculation
- Q: I am looking for a 220v transformer with these secondary voltages: 2x13v, 1x9v, 1x3vIt has to be at least 20va.I cant find this anywhere :/
- Transformers with odd voltages, specially with 4 windings are not really available. You need to find a different way to do whatever it is you need. Or get one custom made, expensive. One alternative is to get a 220v 100 VA transformer to, perhaps 12v, and remove the existing secondary, counting the turns. Say you count 20 turns. Then using smaller wire, wind two windings of 22 turns each, for 13 volts, one of 7 turns for 9v, one of 5 turns for 3v.
- Q: I am looking into purchasing a counter top coffee roaster that requires a 30 Amp 120 outlet; manufacturer says it uses about 21A.The only plug/circuit that can handle this load at this time is a 240 V outlet. We have a gas stove and we are not currently using the circuit.Does anyone know of a manufacturer that makes a external/freestanding step down (240 to 120) voltage transformer / regulator that I can plug into a grounded (North American) 220V outlet ? Note: a) I don't need it to be variable, just a fixed 240V to 120V is perfect. b)It would also need some sort of internal voltage regulation/ stabilization as erratic voltages would affect the (coffee) roast.
- a regulator
- 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: advantages of power transformers
- it is used to step-up or step-down the voltage when used to transfer electrical energy over long distances. to put it in simple terms - the voltage is stepped up from the power generation plant so that there is a minimal loss of electrical energy when it is being transferred through wires. and it is stepped down when it reaches the destination for usage.
- Q: I hate feeling the need to justify myself, but I've seen a lot of answers telling askers to do their own homework. I'm trying to do so, but can't find any equations in the book relating power to voltage as well as turn number. Is it PviN? I've just seen Pvi, but that wouldn't apply to multiple loops. This is for ideal transformers by the way, so power for the secondary and primary coils is the same right? But are their vi's equal, or their viN's?The primary coil of a transformer has 200 turns and the secondary coil has 800 turns. The power supplied to the primary coil is 400 watts. What is the power generated in the secondary coil if it is terminated by a 20-ohm resistor?
- The turns ratio is 4:1 of the primary. The power supplied to the primary is 400W. So regardless of anything else, in a ideal transformer, 400W is available on the secondary. But voltage will be 4x higher, current 4x smaller, than the voltage and current in the primary. Disregarding all that, if there is 400W of power flowing in the primary, then 400W will be being dissipated in the 20 ohm resistor. Watts in watts out, but secondary load (resistance) controls the wattage. There is no way to tell the output voltage and current, without knowing the input voltage and current. But whatever they are, the product of voltage x current will be 400W, in this instance.
- Q: If on the secondary coil we tapped the center to ground, why is it that the top to middle is opposite in polarity when compared to the middle to bottom of the inductor? Also does this only happen if their is a change in current and not constant current going through the transformer?
- the first question think of it as a single coil, 24 V transformer when you measure from bottom wire to the top wire you will measure 24V if you measure from bottom to center it will be 12 V the same from the center to the top maybe it is easier to understand if it were 2 batteries in series images.google.ca/images?hlfrsou at the moment in time that the top is +12, the bottom is -12 therefore giving the 24V this is always like that regardless of the nature of the load Anita
- Q: I think the power supply to my external hard drive has failed. Is there anyway I could replace the transformer. There is no way to contact the manufacturers as they have the worst customer services ever (Formac). I have emailed them 5 days ago without a reply.
- The in the manual or on the device it should state what the voltage and current or power requirements are. It will state this in volts (in AC or DC) along with milliamps (mA) or watts (W). The wall wart should also state what it has on its output. Typically the outside is negative with the inside being positive. Make sure that any aftermarket or replacement transformer is exactly the same voltage. The amperage or wattage capacity should be the same or greater. (ie a 300 mA can be replaced by a 500 mA or 0.5 A but not a 100 mA) The obvious match of the connector should not be overlooked. If it is too big it will not fit, but if it is too loose it may cause excess current to be needed and may damage the device. An electronics store should be able to set you up with a multi-adapter, multivoltage charger / DC powersupply. Here are some examples of replacement supplies.
- Q: 1. a district 800 + a layer of 500mm2 shopping malls should choose how much capacity? 2. A 315kva transformer has been for a district 600 households electricity, ask there is a 70 households can access the transformer?
- 800X8 = 6400KW 6400KWX0.5 (use factor) = 3200KW + 50KW mall = 32500KW (full load operation) Choose three sets of 1000KVA transformer ,, 3000 (KVA) X0.9 (functional factors) = 2700KW · · · · · · · · · · · · · · · · · · · · · · · · · 315KVA transformer for 670 is too small ,,, 670X8 = 5360KW, 5360X0.5 = 2680KW 2680KW / 0.9 = 2977KVA Choose three sets of 1000 phase change
- Q: how could I describe the physics of transformer?
- In electricity, a transformer is like a simple machine. It is a device used to turn large amounts of voltage with low current into small amounts of voltage with high current or vice verse. The power (IV) remains the same, but you can raise and lower voltages as necessary.
