Q:Power transformer primary current and secondary current
For three-phase transformers: Transformer rated capacity = root number 3 X Transformer rated current X Transformer rated voltage So the rated current of the transformer = rated capacity of the transformer / (root 3 X transformer rated voltage) Such as a 100kVA three-phase transformer, the primary voltage of 10kV, the secondary voltage of 0.4kV, then: Its primary current: I1 = S / (1.732XU1) = 100 / (1.732X10) = 5.77 (A) Its secondary current: 2 = S / (1.732XU2) = 100 / (1.732X0.4) = 144 (A)
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:Hi Guys.I'm a college a student who is wondering which tablet to buy. I really can't decide.I want to have a good tablet that I can type and hand write on it. A Tablet that can play 720p and 1080p mkv files. A Tablet that is good for pdf reading. This is all I want. The problem is these two tablets are really good. The New Ipad is running IOS 5 while Transformer Infinity is running ICS.I haven't had tablet before so I have no experience, please I'm open to any advice.
Lol I am having the same problem I think I might go for the iPad tho because I have heard a lot better reviews for it but it is more money and if it is the keyboard that u really want u can get one that connects over Bluetooth to the I pad
Q:What is the impedance voltage standard of a power transformer?
High-low 12-14%, medium-low 7-9%; buck: high - medium 12-14% High - low 22-24%, medium - low 7-9%
Q:how to ground transformers at substations??
an earth ground is made at the transformers sub-station. This is made by driving a copper rod (uffer?)deep into the earth,the depth set by the size of said transformer.A portion of the (uffer?)or ground rod is left exposed and a ground wire/strap is attached to it
Q:And what are the prospects for Transformers 3? I mean, should i just skip it?I forced myself to watch Transformers Twice. Didnt care for it much, either time. Barely, BARELY passable.
Hollywood EF'ed up the first one to make the second one
Q:Hi there, I live in the Dallas, Texas area and we recently had a lot of storms come through. During one of the storms I was looking out a window to my backyard when I heard some thunder and saw some lightning hit the transformer right outside my backyard, which sent sparks everywhere. The power went out, but came on about a minute later.Ever since then (it's been about 24 hours) all the lights in the house have been dimmering every few minutes, some lights dimmer when you turn on appliances and one outlet went out randomly.
Hi, You should check out first with your neighbours and then with the power house. In case if the problem is with your lighting then you will need to get it fixed. You can opt for LED light bars as they are easy to install, consume less power and are long lasting. They are cost effective and reduce the cost of maintenance.They provide equal amount of light like the traditional sources of light while consuming less energy. So you can save on the electricity costsas well. Cheers
Q:hi guys can any of you give me advice on wot i need 2do on removing and replacing a faulty line output transformer on a rear veiw projection tv as i have the part and the local tv shop wont fix it 4 me.wot would be the best way to discharge the power from it first and could i jus cut the 2 wires on the old 1 and use connector blocks to connect the new 1 in would this be ok to do or do it need to soilder connected on?. and is there any adjustments that would need to be done to the set when i have it installed be4 i turn it on any help much appreicated
If you have an identical replacement transformer there shouldn't be a need to adjust anything to start. As to cutting wires to remove the old transformer to replace the new one, I suggest you make yourself a chart of any color coding of the wires or tagging them so there is no error as to what to connect to what on the new transformer. I personally would replace the transformer as the manufacturer installed the original one. As for discharging, use a 10K ohm resistor with one side to ground and the other side of the resistor to the components you want to discharge. I don't advise just grounding direct. Good luck and be careful.
Q:I know that in a step-down transformer if I have 10 turns on the primary coil and 5 turns on the secondary coil that the voltage gets reduced by half and the current gets doubled, but is there any other significance?
Often wondered this myself. There must be a reason why you get transformers with 1000 turns on the primary, and 500 turns on the secondary. If there wasn't a good reason why would manufactures bother putting more than 2 turns on the primary and a single turn on the secondary? The ratio remains the same! Think it could be something to do with the impedance the transformer offers to the input, and output circuits. impedance is kind the AC equivalent of resistance. If it's high then there'll be a fair impedance(resistance to the instantaneous flow of current for a given instantaneous voltage. More turnslonger wirehigher impedance? Matching of impedance between circuits can be important to ensure maximum efficiency/preventing echos etc.
Q:If I have a primary coil and secondary coil each with 400 turns that acts as a transformer, and the primary potential difference is 2.988 V, and the secondary potential difference is 0.0551 V.I need to find the efficiency. Ideally, it would be 100%, but this is the real world. So I did N(turns) and Volts and used the equation [N(p)V(s)/N(s)V(p) ] *100%p primarys secondaryNturns of coilV potential differenceI had an answer of 1.84% which seems awfully low. Help please. Thanks!
You are right. The efficiency is that low. Take a look at it another way: Pin Pout if 100% efficient. Since we know a 1:1 turns ratio will produce the same voltage from one side of the transformer to the other, the current produced on the secondary is extremely low to pull the voltage down to .0551V. It makes this transformer extremely inefficient! I can't even think of how you would design a transformer that was this inefficient. I think even a large OD iron nail with a lot of eddy currents at 7.5k Hz I believe would be more efficient. The next worst way I can think of how to produce an isolated output is with a TEC using the Seabeck effect that is about 6% efficient.
