- Q: What is the transformer through the full and half through the problem, the definition of a little more, the best reference, or sent to my literature.
- Dual split transformer compared with the general power transformer, there are four important impedance parameters: (1) through the impedance: two low-voltage winding in parallel, the high and low voltage winding short-circuit impedance, that is, high-voltage winding short circuit, two low-voltage winding in parallel after adding the current equivalent impedance. Where the reactance component is referred to as crossing the reactance. (2) half-crossing impedance: one of the two low-voltage windings open, the other low-voltage winding between the high-voltage winding short-circuit impedance, that is, high-voltage winding short circuit, a low-voltage winding open, and the other does not open the low-voltage winding power Value impedance. Where the reactance component is called a half-pass reactance.
- Q: If load loss of a transformer at full load is 100kW, the load loss at 50% load will be a) 50kW b) 75kW c) 25kW d) 100kW. i think its 25kW because load loss is inversely proportional to the square of loading percent. kindly explain . is it right.
- I'm guessing load loss is the same as copper loss, which is due to the resistance of the wire in the transformer. This loss is (I^2)(R wire) so the answer is c) 25 KW The current is 50% at 50% load, I^2 0.25

- Q: I love the movie transformers and cant wait till part 2.Anyone know anything about it specifically???
- The combat scenes have been much extra extraordinary in this one than in the 1st movie plus that they had some extraordinary new characters. i'm unable to %. only considered one of my admired areas from the recent Transformers so i visit %. my precise 3, all of them are from the combat scenes. a million. while Optimus top rips that significant robotic's face aside together with his hooks precise in the previous he gets killed himself. 2. while Optimus top tells the Fallen that he needs his face and rips off a million/2 his face in the previous stabbing him with that sick weapon. 3. while the very previous Deceptagon who became to the Autobot facet includes help in the extensive conflict scene and slices one guy in a million/2 in the previous getting attacked via the robotic panther. He then yells i'm getting too previous for this crap precise as he squashes the panther under his fist. classic. there have been many different great moments and scenes and it became into quite this summer season's blockbuster and became into quite nicely well worth the money for the value ticket. Megan Fox became into warm in it too yet she became into quite not the only relaxing area of this movie.
- Q: A transformer is used to step down form the New Zealand mains voltage of 230 V to 110 V for use with an electric razor from the USA. (a) If the razor draws a current of 0.15 A what current (at least) is drawn form the 230 V line? (b) What is the ratio of the loops in the primary and secondary coils of the transformer?Could you please include the equations you used, and your working.
- Since there is no evidence to indicate any inefficiency of this transformer, you have to assume that it is 100% efficient, with input power equaling output power. Input power Vin * Iin Output power Vout*Iout Equate: Vin*Iin Vout*Iout Solve for Iin, our unknown: Iin Iout * Vout/Vin Data: Vout 110 V Vin 230 V Iout 0.15 A Result: Iin 0.072 As for the ratio of loops, the number of turns in each coil is proportional to the voltage across each coil. Thus, the turns ratio equals the voltage ratio of 110/230 0.478. That is to say, there are 2.1 turns in the primary coil for every individual turn there is in the secondary coil. The primary coil is the coil plugged in to the line voltage of 230 V. The secondary coil is the coil in to which the load plugs in, at load voltage of 110 V.
- 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 am re-winding transformers, and I was wondering if braided copper wire can be used for the secondary winding. I will be using large gauge wire (4-8 ga.) and I just need to know if the performance will be terrible if I do use it.
- Not ideally. You should be using solid lacquered or varnished wire.
- Q: I need a (step-down) Transformer of the following specifications:240VAC to 24VAC 10A or 240VAC to 24VDC.(Output as 24VDC would be better/easier).I live in Victoria, Australia and need one ASAP (next 3 days or sooner)Plz tell me any store or so Also, if u wanna know the VA Rating, its 240VA.If 10A is not available then anything closest to it. say 9 or 8.5 or 8 or 6.5.Cheers!
- Transformers only work with AC, so the second choice is not possible. But you can buy power supplies that have a DC output. Reference has one possibility. Search google for buy supply 24v 10a and you will find lots more. .
- Q: Exactly what is the storyline of the Transformers. As far back as I know, there were two brother, Unicron and Primus who fought each other because Unicron wanted to suck up Universes. But where did these two come from? Does it even say?
- I am a fan but I haven't been able to find that out myself, if you find out let me know.
- Q: Here we go I have 4 transformers (230V to 12V) and 4 radio receivers. I have one transformer connected to one receiver. Similarly all transformers are connected in the same way. Now, I used a connection box (normal heavy duty ones bought at hardware shop-i think its made of some kinda fibre) to house 2 transformers and 2 receivers. This scenario is happening in my roof. I went to open one of the box the other and the transformer was hot. It wasn't hot to the point of not being able to hold it. But hot enough for me to hold it for for a while before letting go. So the basics here is that one transformer is only powering one receiver which is OK for the load. But I am a bit worried as to whether this can start a fire in the roof. Any advice please? Can this scenario lead to a fire? (Even though there is no overloading)
- Pete's answer is a winner. The only thing I'd add to it is that all electronics that generate heat must be vented. You didn't say you had any venting. Sometimes that venting can be convective current venting (hot air rises, cool air enters from below) OR can be a cooling fan. Like Pete said, without specs and loads we can't tell for sure if there's a danger. And until you KNOW there is no danger, assume there is. Hope this helped. '')
