- Q: Transformer parameter interpretation
- Transformers in the provisions of the use of the environment and operating conditions, the main technical data are generally marked on the transformer nameplate. Mainly include: rated capacity, rated voltage and its tap, rated frequency, winding connection group and rated performance data (impedance voltage, no load current, no load loss and load loss) and total weight. A, rated capacity (kVA): rated voltage. Rated current under continuous operation, can deliver capacity. B, rated voltage (kV): the transformer can withstand long hours of operation can withstand the voltage to meet the needs of the grid voltage changes, the transformer has a high voltage side tap, by adjusting the number of high voltage winding to adjust the low voltage side of the output voltage.
- Q: Any help much appreciated here, I cannot understand the following formulas at all. If there is anyone who can please explain in very SIMPLE words I would be very grateful. My exam is next week and I am still stumped on the following.VP/VS NP/NS IS/IP ok this bit I understand, but then here are the QAs that don't make sense to me:Q1) A single phase transformer has 1250 primary turns and 200 secondary turns. Primary V I are 230V and 3A. What are the secondary V I?A) 1250/200 230/vs transpose too: VS 200 X 230/1250 36.8V Why has it been turned upside down?230/36.8 Is/3transpose too: Is 3 X 230/36.8 18.75A Why??The following Q I am even more stuck withQ2) Single phase transformer has a rating of 300/230V, 15KVA. What is the full load of primary and secondary?A)S VI Where did S come from?!Ip 1500/3300 4.55A KVA - is this taken as the V? Not I? Is that why Is 1500/230 65.22A it has been reversed? I'm very confused, please can someone help explain this process to me?
- This seems to be about transposing equations rather than transformers! Let's go through it one step at a time. VP/VS NP/NS IS/IP OK So far. Q1) A single phase transformer has 1250 primary turns and 200 secondary turns. Primary V I are 230V and 3A. What are the secondary V I? Voltage first. So you are given Np 1250, Ns 200 and Vp 230 VP/VS NP/NS 230 / Vs 1250 / 200 Multiply both sides of this equation by Vs Vs * 230 / Vs Vs * 1250 / 200 Simplifies to: 230 Vs * 1250 / 200 Multiply both sides by 200 200 * 230 200 * Vs * 1250 /200 Simplifies to: 200 * 230 Vs * 1250 Divide both sides by 1250 200 * 230/1250 Vs * 1250/1250 Simplifies to: 200* 230/1250 Vs Vs 36.8 volts OK. Now the current. You are told that Ip 3 amps VP/VS NP/NS IS/IP Now you know Vs 36.8 volts, you have a choice as to how you set the equation up. You could use either: VP/VS IS/IP 230 / 36.8 Is/3 or NP/NS IS/IP 1250 / 200 Is/3 Either way, multiply both sides by 3 3 * 230 / 36.8 Is or 3 * 1250/200 Is Both give Is 18.75 amps Q2) Single phase transformer has a rating of 300/230V, 15KVA. What is the full load of primary and secondary? There is a typo in this question. The rating is really Vp/Vs {which is supposed to read 3300 V / 230 V} and the maximum value for the product of (Vp * Ip) 15000 (volts * amps) { K 1000 } {Which for our purposes is the same as (Vs * Is) } So we know that on the primary side: 3300 * Ip 15000 Divide both sides by 3300 Ip 15000 /3300 Ip 4.55 A and on the secondary side: 230 * Is 15000 Divide both sides by 230 Is 15000 / 230 Is 65.22 A Hope that helps.
- Q: 50kva transformer price
- 2, Transformer (Transformer) is the use of electromagnetic induction to change the principle of AC voltage device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
- 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: assuming a delta connected single phase transformers , why is the neutral side is connected to ground, my question is will the current be shunted to ground since it has a low resistance??? please explain
- In electric distribution structures transformers are available countless sizes. Heavy ones are generally located on the floor with a concrete pad located under it to furnish help. those pad fastened transformers are risk-free against touch with the regularly occurring public generally with a fence. Pole fastened transformers are lighter and can be accurately located immediately on the skill pole. i don't comprehend of any floor fastened transformers different than for transformers located in vaults while the distribution strains are underground. yet those additionally desire some form of pad under them.
- Q: I hate feeling the need to justify myself, but I've seen a lot of answers telling askers to do their own homework. I'm trying to do so, but can't find any equations in the book relating power to voltage as well as turn number. Is it PviN? I've just seen Pvi, but that wouldn't apply to multiple loops. This is for ideal transformers by the way, so power for the secondary and primary coils is the same right? But are their vi's equal, or their viN's?The primary coil of a transformer has 200 turns and the secondary coil has 800 turns. The power supplied to the primary coil is 400 watts. What is the power generated in the secondary coil if it is terminated by a 20-ohm resistor?
- The turns ratio is 4:1 of the primary. The power supplied to the primary is 400W. So regardless of anything else, in a ideal transformer, 400W is available on the secondary. But voltage will be 4x higher, current 4x smaller, than the voltage and current in the primary. Disregarding all that, if there is 400W of power flowing in the primary, then 400W will be being dissipated in the 20 ohm resistor. Watts in watts out, but secondary load (resistance) controls the wattage. There is no way to tell the output voltage and current, without knowing the input voltage and current. But whatever they are, the product of voltage x current will be 400W, in this instance.
- Q: Hi there.I have purchased a Stepdown Transformer so i can use a Record Cleaning Machine I am buying from the U.S.It uses a powered suction unit to clean the record.All transformers for use with American equipment have 110v output, but i think your equipment is usually 120v.in I have been told that there is nothing to worry about as 110v out on the transformer is enough to power the equipment connected to it .Our AC output in Australia is 240v but we can use any voltage from 220 to 250. Therefore 110v should be enough.can anyone clarify and tell me it should be ok.Thanks a lot in advance.
- I live in New Zealand. We use 240v 50Hz mains here too. USA uses 110/115v 60Hz. There is a 10Hz voltage frequency difference as well as the voltage difference. The stepdown transformer will be rated for 110v RMS(root-mean-squared). This is a kind of average, for want of a better description. The peak voltage is 0.707 times the RMS voltage. This is the peak on one half of the sine-wave(180'), therefore the complete sine-wave mains frequency represents 1.414 times the RMS voltage.(360' sine-wave cycle) Multiply 110v by 1.414, and you will get the peak-voltage, which is the maximum that the AC voltage can swing, both in the positive and negative parts of the sine-wave. 110v example: 110 x 1.414 155, therefore, the PEAK voltage for the States is 155v AC, or thereabouts. 240v example: 240 x 1.414 339, therefore, the PEAK voltage for Aus/NZ is 339v AC, or thereabouts. All mains voltages are a measure of averages(RMS), so a 10 or so volts either side of the stated voltage, should not prove to be a problem. Provided that the stepdown transformer can supply at least a few amps of current on the secondary(the 110v side), there will be no problems at all. Technically, the 10Hz frequency difference can make a slight difference, especially if you are trying to power some sound equipment from the States, as the Australian/New Zealand 50Hz frequency will mean that the motor will run slightly slower then the designed RPM. However, in your case, I don't think it will make one iota of difference. :)
- Q: What is a transformer?
- First talk about the buck, usually we use a variety of voltage, such as life lighting is 220V, industrial safety lighting is 36V, welding machine voltage also need to be adjusted, which are inseparable from the transformer, the transformer through the main and auxiliary coil electromagnetic Mutual inductance principle, can reduce the voltage to the voltage we need. In the process of long-distance voltage transmission, we need to raise the voltage to a high, in order to reduce the voltage loss, usually rising to several thousand volts or even tens of kilovolts, which is the role of the transformer.
- Q: Transformers are hot like boiled water. Will this be bad for a long time? How should i let it cool. The
- Summer transformer is very hot, the notebook's own heat is more important to keep the room temperature the most important, too high temperature, then no matter how cool! Open the airplane with a laptop! At the same time should try to make the bottom of the notebook overhead, can be used special cooling bracket or with equal thickness and small size items (such as chess pieces, military flag, laminated one dollar coins, tape boxes, etc.) the bottom of the notebook pad! Try not to use the key film, because the keyboard is an important part of the notebook cooling! Other parts of the cooling (each brand of notebook cooling parts may be different) should not have object coverage! Summer is up, the notebook needs your double care Oh!
- Q: I have a few questions about flyback transformers: How high of a frequency can they go without alot of losses?Can I get a negative High voltage by reversing the polarity of the primary?How can I make the flyback safe from the capacitive charge that it holds?
- The flyback transformers used in TV's work at about 15000 hertz (the horizontal scan frequency). The transformers used in switching power supplies are smaller and work at a higher frequency, but they normally have a low voltage output. The transformer produces a high AC voltage, and a rectifier diode changes it to DC. Reversing the diode gives you a negative output. The picture tube provides capacitance to smooth out the voltage and holds the voltage for a while after the power is turned off. If you don't use a picture tube, you might need a capacitor if you want a steady output voltage. Shorting out the capacitor will remove the voltage.
