Q: I have two questions about electrical transformers1.Do all transformers come with wires so I can hook it up and plug it into a wall? If not, where can I get those?2.If I don't have anything to sauter wires, could I use eletrical tape instead? Which sounds sloppy.: 1. Transformers don't usually have plugs on them. 2. The word you want is solder. Tape will work, but it is sloppy.

Q: A single phase transformer operates from a 230V supply. The primary and secondary resistances are 0.03 Ω and 1.12Ω respectively while the corresponding leakage reactances are 0.1Ω and 6.4Ω; the magnetising branch can be neglected. The secondary winding has four times as many turns as the primary. Calculate :i) The equivalent impedance referred to the primary circuitii) The secondary terminal voltage when the load has a resistance of 200Ω and an inductive reactance of 100Ω.iii) The secondary terminal voltage when the load has a resistance of 200Ω and a capacitive reactance of 100Ω.Can someone show me how to tackle this question please?: i) the secondary transformer impedance is 1.12 + j6.4Ω. Since Ns/Np 4, this impedance reflected to the input is (1.12 +j6.4Ω)/(Np/Ns)? 007 + j0.4Ω ii) Reflect the primary transformer voltage and impedance to the secondary side. 230(Ns/Np) (1.12Ω + j6.4Ω + (Ns/Np)?(0.03Ω + j0.1Ω ) +200Ω + j100Ω )I 920 (1.6 +200 + j8 +j100)I (201.6 + j108)I |Z| 228.7Ω √(201.6? + 108?) at angle of inverse tan (108/201.6) 28.18° I 4.02 amps at -28.18° 3.54 - j1.90 amps The terminal voltage is 920 - (1.6Ω +j8Ω)(3.54 - j1.90 amps) iii) solve 920 (1.6Ω +200Ω + j8Ω - j100Ω)I (201.6Ω - j92Ω)I The terminal voltage is 920 - (1.6Ω + j8Ω)I

Q: An AC generator, originally designed to provide a peak output voltage of ± 155 V at a frequency of 60 Hz, is required to provide a peak output of ± 340 V at 50 Hz. If the generator is connected to a transformer with 200 loops in its primary coil, how many loops should there be in the secondary coil in order to provide the required output?Using the formula Np/VpNs/Vs I get 439 coils, but this is too easy for a 6 mark question and doesn't include the change of frequency. I have no idea what to do and need some help :(: Transformers cannot change the frequency of an electrical signalperiod. It requires more sophisticated electronics to do that. Perhaps your instructor is confused.

Q: I have a 150 watt bank of photovoltaic cells that run at 12 volts (PWM mode non-mppt charge controller). My question is, by substituting a dc transformer (one that boosts current and steps down to 12v) for a current boosting mppt, can I run the solar panels at their full rating even though they are connected to a 12 volt battery bank? The 12v batteries, when directly connected to the solar panels, drop the output because the panels output their full current at a higher voltage.I am also wanting to apply this logic to a wind turbine that outputs a maximum of 30 volts dc. I am thinking that if the switching transformer works for the solar panels, it would also work to step down the wind turbine's harsh dc voltage to a current boosted 12v state. Would this theoretically work?: Homemade okorder

Q: 500KW load should be installed how much transformer?: P = 500KW cosφ = 0.8 Apparent power S = P / cosφ = 500 / 0.8 = 625KVA You should choose the power of 625KVA transformer. Because there is no 625 series of products, you should choose a capacity of 630 kVA above the transformer. If it is with the motor and other load-based, due to power factor and start-up 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 heard that there is an electric transformer used in single phase electric furnace and other applications , its benefit is to get more balanced current load from the three phase system to feed a single phase load.i need to know how its can transform three phase supply into single phase supply, and if it can be used in reverse matter i.e can it deliver a three phase power from single phase supplythank you in advance: this okorder

Q: I got an Alien bees unit and in order to convert the power from 120v to 220v I have to get a true magnetic transformers according to their website, what does that mean?: All transformers are magnetic. Perhaps if you would provide a link to the product in question, maybe even to its user's manual, some more information could be gleaned that would allow a more helpful answer. I have no idea what an alien bees unit is. -------- Ok with that I was able to google some more info. So you have a unit that came with a 120V power cord, intended to be plugged into a north american AC power outlet (120V, 60 Hz), and you need it to run on your local current, which is 220. You don't have a power brick or wall wart, the AC goes right to the flash unit. Yes? And the specs say it draws up to 6 amps at 120 volts, 60 Hz. What they're talking about is that you need a true voltage conversion transformer (usually this is actually an autotransformer), NOT any other sort of voltage converter. Travel stores in this country (US) sell these small and cheap voltage converters, made to allow use of certain high wattage devices (up to 1500 watts) on 240 even though they're made to run on 120. But they don't use a transformer, they use a capacitor and a diode. They're ok for things like curling irons and space heaters. They're completely unsuitable for anything electronic. You can usually tell the difference between a true transformer voltage converter and the voltage converter by weight. The latter weigh just about nothing. Whereas even a 50 watt transformer will sit fairly heavily in your hand. For a device that pulls 6 amps at 120 volts, you need a transformer of at least 1000 watts capacity. I've linked one below. Of course that is a US seller, but this will give you an idea of what to look for. Note that it weighs 17 pounds (about 8 kg) and is about 5 x 7 x 8 inches (13 x 18 x 20 cm). There just isn't any way these get much smaller or lighter. .

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: I assume the new transformer is 230/110v? If the contactor coil is rated 110v, it should be fine. Most contactor coils, as with most electrical equipment these days have a large voltage tolerance. However, you need to check that the contactor coil is rated for 110v. You may find it's rated for 100v to 120v.

Q: A step-up transformer is connected to a generator that is delivering 131 V and 96 A. The ratio of the turns on the secondary to the turns on the primary is 859 to 1. What voltage is across the secondary? An-swer in units of kV.What current flows in the secondary? Answer in units of mA.: Vp Voltage Primary Vs Voltage Secondary Np Number of Turns Primary etc The values you have given are primary, why? Because its Generator Transformer (GCSE stuff) Equation : Vp/Vs Np/Ns 131 / Vs 1 / 859 Vs 112529 V (large cause its a step UP transformer) 2). This equation is similar just slight different order: Vp / Vs Is / Ip (Hence you can rearrange this for power but not needed here) 131 / 112529 Is / 96 Is 0.11 A (2dp) Yet again you'd expect it to be small, because your transforming your voltage upwards to reduce your current (which of course creates less heat so less heat energy lost etc)

Q: even though the output voltage of a transformer can be much larger than the input voltage, the power output is nearly the same as the power input.Determine the relationship between the input and output current and the number of turns in the input and output coils.help!!!!!!!!thank you: If turns ratio is N, output turns divided by intput turns, then voltage ratio is also N, and current ratio is 1/N For example, a 120 VAC transformer with a 12 volt 10 amp secondary will have a turns ratio of 1/10, a voltage ration of 1/10 (12/120) and a current ratio of 10 (1 amp in primary, 10 amps in secondary) .
