Q: For my proposed new aluminium extrusion factory I ve the load of 250 kw heater and 670 HP of motors.Whats the kva rating of the transformer I should go for?Pls advice.: the kva rating of the transformer shows that the power factor of the load has been taken care of

Q: i need to have an immediate answer (solution to this) thanks:Determine the transformer bridge rectifier and filter capacitorspecifications/values required to produced an output current of 3A and a nominaloutput voltage of 17VDC with a ripple voltage of 2 Vpp. Assume a line voltage(from Meralco) of 220VAC, and that the design is to use a center-tappedtransformer.2. Given the characteristics of the raw DC supply just designed, determine thecomponent values of a transistor regulator circuit (based on “Simple TransistorVoltage Regulator Circuit” from the CCS1: If you want to step 12 volts AC to 96 AC, you need a transformer with a primary to secondary winding ratio of 8. You then connect the 12 volts to the secondary, and will get 96V at the output. The most accurate way to do this, is go to a transformer shop and ask them to do this. They will ask you for current requirements. If this is not an option, go to a hardware store and ask for a 120V to 15V (or whatever value is closest) transformer. Keep in mind that while voltage is multiplied, current is divided, so that at the end you get the same power. So, if you have a transformer with n8: V12*896 volts I 110/813.75 amps

Q: High-rise residential basement transformer noise is too large, how to solve, whether the need to shift, there is no other way to solve! Thank you as much as possible! If you have to do this project also please educated us!: Transformer noise is mainly caused by magnetostriction of silicon steel sheet. method: 1, choose a reasonable magnetic density; 2, core clamping; 3, pad to take shock measures; 4, the tank within the parts fastening, does not allow loose metal parts or standard; 5, all the accessories on the tank must be tightened; 6, the use of low noise fan; 7, the installation of the basic level. Dry-type transformers do not have fuel tanks, remove the other 5, the same, because the dry-type transformers do not have the mailbox, the core magnetic choice, parts fastening, installation foundation leveling is more important

Q: A 8000kva transformer can bring the maximum load: Transformers are best not to run full of the efficiency of remember the best 60 to 80%

Q: What are the specifications of the transformer capacity?: The choice of transformer capacity has a great impact on the comprehensive investment efficiency. Transformer capacity selected too large, there "big horse car" phenomenon, not only a one-time investment, no-load loss is also large. Transformer capacity selected too small, transformer load loss increases, economically unreasonable, technically not feasible.

Q: How can the locations and polarity of the windings be tested on the various legs of a core when it has 2 open(circuited) three pahse windings (III and iii)?what measurements are required , assuming that the transformer is so enclosed that only the 12 winding terminals are visible?Ohmmeter , voltmeters , a single phase voltage supply are available.: It sounds like you have a three phase transformer. In the cover plate there normally is a drawing to guide you on what you want to do. Most trans formers can have input voltages of 440 volts in to 240 ouput. but some can provide 115 volts on the output if wired correctly. Any transfomer compnay website provide wiring drawings that pretty match everyones transformers. Contact the manufacturer of the transformer for instructions.

Q: I am making a small Tesla Coil, but have a question regarding the transformer. Would it work to simply wind one myself with the correct winding ratio to get the voltage I want (around 7-10kv) or is it better to stick with a commercially available transformer? (I would rather not have to buy one) Any advice for winding a transformer?: I say buy one or find one that you can have for free. Whenever I build a Tesla Coil, I consider the transformer the first line of protection for pretty much any electronic circuitry on the same mains line because it acts to isolate the Tesla coil. I would never operate a home built transformer off of mains power. However, if your insistent on doing that, all I can do is advise you to get the resistance of your primary right, otherwise your transformer will quickly melt. An easier solution would be to find and contact neon sign businesses around your area. When they have to discard an old (but not necessarily bad) transformer, it COSTS them money because the EPA requires special handling because some can contain hazardous materials. Explain what your doing and if youre lucky, youll find a tech who is open to giving you a few of their junk stock.

Q: Do stores that sells computers, printers, etc. also sell transformers: Transformers as in the action figures? You can find them at Toys R Us, Wal*Mart, or Target.

Q: I want to make a simple flyback transformer driver. I have a flyback transformer of samsung CRT monitor. Can anyone give me a complete design of flyback transformer's pin. What are the required components. Please give answer in detail.: submit a schematic and a few concepts on the transformer. Circuits with transformers continuously have some inductive power that could desire to be dissipated whilst the transistor(s) turn off. this could reason extreme voltage spikes which could unquestionably injury a transistor (whether the case isn't warm). you may desire to guard in comparison. A 2N3055 is an quite sluggish gadget and not very proper for top velocity switching.

Q: I have two-way transformer (120Vlt;240V) that has a surge capacity of 2000W and a continuous capacity of 1600W. The transformer is plugged into my wall socket and is, on its output side, attached to a power surge protector that leads to six separate sockets. There are periods where not all six sockets are in use - in this specific case, the only appliance is a 50W fan - and my question is, does the transformer still eat 1600W off my meter and waste most of it as heat, or is it nice and intakes maybe only 60W and inefficiently converts it to the required 50W? If the company/model comes into question, I can only say the transformer is of Taiwan origin - the company logo is a 'Z' with small D intersecting the two parallel lines of the former letter, all against a blue background - and has a model number of TC-2000. Many thanks.: the thought is sure and NO. sure, by way of fact a transformers considerable coil has a undeniable resistance. Wattage used is a function of voltage cases modern-day. on the grounds which you recognize the enter voltage is a hundred and twenty V, in case you are able to degree the coil resistance you are able to calculate the present used. Multiply modern-day cases voltage and you get wattage. although, the character of a transformer is extra desirable than basically a trouble-free function of Ohm's regulation which you would be able to seem up on the internet. there is yet another function of a transformer that could desire to be further into the equation, and that i'm not an authority on that. although, this extra ingredient is talked approximately as Inductance. that rather skill that reckoning on the burden of the output, the enter wattage will replace, however not heavily. Suffice is to assert that a transformer it is plugged into the wall yet isn't working something DOES proceed to apply power. you are able to tell this by way of fact the transformer would be warmer than if it weren't plugged in in any respect. this is going on on the grounds which you're changing electric powered modern-day into warmth - you're making use of electricity. on your case, making use of a decrease wattage bulb (this difficulty LED) you will use much less power, yet will in no way be saving a form of electricity. If going green is the objective, you would be extra valuable off making use of a hundred and twenty v LED lights OR a low voltage device it is designed around using LED. to easily set up LED will consequence in little or no decrease fee rates at an exceedingly huge fee. LED lights isn't decrease priced. solid success. :)
