- Q: I am working on a lengthy project and have one little area that I am not sure how to answer. I need to know how to size a transformer for a building. Does anybody know the equation or method for doing this? The service coming in is 480Y/277V and the step-down is to a 240/120 single phase panel. Any help is great! Thanks
- buildings come in all sizes. Some use a lot of power, perhaps because of lots of machinery. Others use a much smaller amount. So you need to calculate or estimate the amount of power the building will be using. If you know the square foot total and use of the building (industrial, office, etc) there are probably tables that will give you a guess. One 240/120 panel for the entire building? That implies a very small building, as must buildings distribute 3 phase 208 volts, and have numerous subpanels. .
- Q: Rectifier and rectifier transformer
- 1) rectifier transformer is the rectifier device power transformer. Rectifier equipment is characterized by the original input current, and vice president through the rectifier output after the original DC. Converter is rectifier, countercurrent and frequency conversion of the three working methods in general, rectification is one of the most widely used. Transformer used as rectifier power supply is called rectifier transformer. Industrial rectifier DC power supply is mostly by the AC power grid through the rectifier transformer and rectifier equipment and get. The application of rectification change the most chemical industry. Simply talk about the industrial high-power DC power supply. Civil rectifier transformers are commonly referred to as power adapters, transformers, power converters. 2) rectifier (English: rectifier) ??is the exchange of alternating current into direct current devices, can be used for power supply devices and detect radio signals. Rectifier can be vacuum tube, ignition tube, semiconductor diodes, SCR, mercury arc and so on. Generally do not contain voltage transformers. Refers to a wider range. Basically most of the electronic products are in use. 3) folk often put the ballast as "rectifier", inductance ballast is a core inductance coil, rectifier is a rectifier device.
- 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: The book said the main transformer power failure operation should first stop the load side after the power side, is to prevent the transformer in the case of multi-power reverse charging. What is the transformer anti-charging here? What's wrong?
- Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. ?????? When the transformer is shipped, it is determined whether it is used as a step-up transformer or a step-down transformer, and its relay protection setting requirements are specified. If the transformer is a step-up transformer, it is determined that the low-voltage side is zero-up. Such as from the high side of the anti-charge, then low side of the open circuit, due to the relationship between the high voltage side of the capacitor current will cause low voltage side due to electrostatic induction and over-voltage, easy to breakdown low-voltage winding. If you determine the normal high-voltage side of the transformer, such as from the low side of the anti-charge, then the high side of the open side, but the excitation current is large (up to 6 to 8 times the rated current). It produces the electric power, easy to make the mechanical strength of the transformer is a serious threat, at the same time, relay protection device may also hide the inrush current and malfunction.
- Q: I use transformers in my circuitry all the time but when a transformer is say a secondary 12v 1a transformer than what does it mean by 1 ampis it that the secondary winding wire will pop after 1 amp doo to the simple thinness of the wire? or that the ohms of the secondary coil, when using iv/r, 112/12so does this tell you that the coil is 12 ohms?please don't give me other information about the transformer just answer the question please.
- It means the transformer secondary voltage is 12 volts and the current rating is 1 amp. If you put a higher current load on the transformer it won't pop, but it will overheat and the insulation will degrade faster than if the current was kept below 1 amp. If the current is allowed to go too high, the transformer will fail in a short time.
- Q: Transformer short-circuit impedance is big good, or small good? The same capacity, voltage ... solution
- Transformer impedance depends on the size of many factors: 1 circuit breaker breaking capacity. Transformer below the power distribution board in a variety of electrical equipment has parameters, you should calculate the short-circuit current according to the impedance of the transformer to verify that these electrical equipment can meet the requirements, the same capacity and variable ratio of the transformer, the impedance of small short-circuit current, Large short-circuit current is small; 2 transformer connected to the large-capacity motor starting voltage. If the transformer load capacity close to the transformer capacity of 1/4 of the motor, should pay attention to check its starting voltage to meet the motor terminal voltage above 70% of the rated voltage. Impedance of the transformer itself is also a large pressure drop, more difficult to meet the requirements; small impedance transformer for the start of the pressure drop better performance; because you do not know how much the transformer capacity, it can not be the absolute conclusion, if the transformer capacity below 1000KVA , The above parameters in 4% and 6% or less, the choice of 4% better
- Q: I want to make presentation about transformers, I need to know suitable definition.I also want to know the Major Components, and Protection devices.Thanks a lot
- A transformer is 2 or more coupled inductors. Usually the coupling coefficient is near 1. Protection devices like fuses and breakers open the circuit when the load current is excessive. Other protection devices include thermal sensors, phase rotation sensors, loss of phase sensors, voltage monitors, 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) .
- Q: Hi, there is a utility pole in my lot and there is also a cylindrical shaped transformer hanging off of it. I did some research on it and it is used to step down the voltage from 7000 volts to 120 volts. Does the EMF (electromagnetic field) it generates pose any health threat to the household? Thanks-jj
- No. The level of EMF is dependent on the current flowing through the wires. The higher the current, the higher the magnetic field. The strength of the EMF also decreases with distance. The pole is at the edge of your lot and the transformer is probably 20' in the air. In reality, high load appliances in your home are much closer to you and your family. The EMF fields measured next to a toaster, microwave oven, electric range, or electric blanket are far higher than you'll likely measure standing below the transformer. In October 2000, Discover magazine published a list of the 20 Greatest Engineering Blunders of the past twenty years. EMF made the list -- Below is the text and a link to the official article. Currents That Don't Kill: The Clinton administration estimates that American taxpayers have paid $25 billion to determine that power lines don't do anything more deadly than deliver power. In 1989, Paul Brodeur published a series of articles in The New Yorker raising the possibility of a link between electromagnetic fields and cancer. Eight years later, after several enormous epidemiological studies in Canada, Britain, and the United States, the danger was completely discounted. All known cancer-inducing agents act by breaking chemical bonds in DNA, says Robert Park. The amount of photon energy it takes is an ultraviolet wavelength. So any wavelength that is longer cannot break chemical bonds. Visible light does not cause cancer. Infrared light is still longer, radio waves longer still. Power-line fields are preposterous. The wavelength is in miles.
