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?: Transformers don't work on DC. You need a DC to DC converter.

Q: Transformer oil filter method: Transformers in the run after a period of time, if due to short circuit and other causes of transformer oil quality electrical test failed to test the need for oil treatment, improve its purity. The main reason for failure is excessive water content, including other impurities. Transformers because it has been oiled and can not be all out of all the oil out of the filter processing.

Q: i need a 120VAC to 160VAC step-up transformer; like, not an already built converter, but a just bulk single transformer. where can i buy one?and don't say go look in OKorder, coz i've already looked and there isn't any: The dimensions of a transformer depend on the required current rating. In some circumstances, you could even use a transformer with a multi- tapped primary. By tapping it lower, you may find 160V between the neutral or common tap and a tap higher up the winding. It would be working as an autotransformer, which is not a particularly good form. I would question for what purpose you would need 160V., anyway? It seems a strange voltage to need.?

Q: I am in 10th grade now, taking the IB next year, and I would like to know if a Transformer is good for things like taking notes in class, and working on projects that we might be allowed to work on in class. I would still have a full computer at home for more serious editing, but I would just like to know if the Transformer TF300 will be good enough for school. Also, I am not only talking about this year, but also the IB, which - if you know it, and I hope you do - will be more work and I would like to know, again, if the Transformer is up to that task.: (warning : poor English) Yes, Transformer Pad TF300 good for school. 1. It have a keyboard (optional), you can take notes faster. 2. Likes all others (pads), there have camera, you can take a photo of the board (if teacher allowed). 3. TF300 battery life quit good, with the keyboard even better. 4. We will work in cloud computing in the near future (or now) mostly. Google drive meet your needs for word processing, drawing, creating simple spreadsheet. you can share your works, or finish your project collaboratively with your group members via internet. 5. the chips: Tegra 3 is responsive, the screen: 10 (1280x800) is comfortable, the OS: Android 4.0 is more suited for tablets and it's a better os overall, the brand: ASUS, manufacture the best Android tablet (imo).

Q: current of the battery , but not through the output of the transformer but between the input and the battery, why is that?: DC does not work on a transformer. Only AC. Putting DC into a transformer is like shorting the battery out. A transformer works by magnetic flux which is caused by the change in voltage (AC).

Q: I understand that transformers used to lower voltage for AC power transmission, simultaneously change both the voltage and current, but if such a transformer were in used in say a 12 volt dc power adapter that plugged into the wall outlet, then it would be counterproductive if the voltage lowering transformer upped the current as too much power would be dissipated, and a current boost would be unwanted, right? Same with transformer for PC power supplies. They must lower voltage without upping the current, right? Thanks a lot.: Transformers are power transmission devices. For a given load and turns ratio, a transformer will convert the input voltage and output voltage per the turns ratio. The current is determined by the load, not the transformer. This current is then transferred to the primary per the turns ratio. For example, if you have a 10:1 transformer that converts 120VAC to 12VAC, but there is no load connected, the current will be zero. So, while you still measure 12V at the secondary, no current can flow because there is nothing connected. If you connect a 1A load, the current at the primary will be one tenth or 0.1A. Thus, the power at the primary (120V * 0.1A) is equal to the power at the secondary (12V * 1A) or 12 watts. Of course, real transformers have losses, so the currents won't come out exact since a small amount of power is lost in the core of the transformer. Exactly how much power loss ocurrs depends on the construction of the transformer. So, transformers convert the primary voltage per the turns ratio, and the secondary current is transformed in the other direction.

Q: From the following transformer, how would I calculate:a) the equivalent impedance on the low-voltage sideb) Converting the impedance found in (a) to it's per-unit quantities: a) the turns ratio of the transformer is 20 to1 so to refer an HV side impedance to the LV side you divide it by the square of the turns ratio which in this case is 400 which gives: 0.001+j0.00025 ohms. b) There's a certain amount of freedom in doing this for you may define the per-unit impedance base however you want. It is however rather usual to define it as VA / I^2. Here I 5000/2400 2.083 amps So base impedance HV side 5000/2.83? 624 ohms making the given impedance (0.4+j0.1)/624 p.u. This p.u. value should be the same on either side of the transformer. Nice to see you around again but do I notice you haven't improved at saying please when you want someone to do something for you for nothing. If you can't learn that there's not much use in learning all these technical skills. You're going to remain a clumsy oaf!

Q: i just got back from seeing transformers and the special effects were awesome but the storyline could have been better. I thought the girl meghan fox was so prettywho thought the same?: my take was, if you're a decepticon, why give away anything until you're ready to strike? think about it, you're an a**kicking supercomputer with crazy weapons and you can hack the sh** out of the most sophisticated systems on this planet in a matter of seconds. you're looking for a seemingly insignificant pair of glasses WHICH ARE FOR SALE ON E-BAY. you can't just hack a bank or large corporation, jack a few million, and give the high school junior a huge amount of money for the glasses and just wait a day for UPS, THEN go for Megatron and the All-Spark? that was the big one for me, also they put too much comic relief on the transformers side. that version of soundwave they put in there was way too cutesy. and sorry dude, but Meghan Fox is just Jennifer Connolly ten years ago, but without the great skin. don't get me wrong, i thought the movie was decent enough, but people are going crazy over it, and it's unwarranted. that's all i'm saying.

Q: What is his calculation? Trouble you prawn.: Transformer economic operating coefficient is 0.75. Transformer output capacity and power factor, the power factor is 1 when the transformer output current is the largest, generally require more than 0.9. When the power factor is 1, the transformer output current I = 250KVA / (1.732 * 0.4KV * 1) = 361A. The observed current is the most intuitive. Three-phase active power P = 1.732 * U * I.

Q: explain the role of both types of transformers in getting electric energy from an electric power plant (coal-fired, natural gas or nuclear) to our homes.: A step UP transformer is used to boost the VOLTAGE, as by doing so the CURRENT is reduced by the same factor, e.g. boost voltage by 100 x, reduces current to 1/100th. By reducing current, power losses due to the transmission line RESISTANCE is very significantly reduced, especially in long run distances between consumers and the generating plant. The formula I^2*R is power, and the square of (say) 100A is 10,000, whereas if the current were reduced by 100 fold as above, the current becomes 1A., so you can see the difference! 1^2 1, versus 100^2 10,000. But the voltage is too high for consumer use, So a step DOWN transformer is used to change the voltage down to the required domestic voltage. The ratio of this transformer can easily be adjusted to allow for the minute power lost in the high voltage lines. The overall effect is very much less power lost in heating the connecting wires in the transmission lines, so much more power available to consumers.
