- Q: Single bus sub-section for power distribution, transformer with a prepared and dual-use how to understand
- One with a prepared, you can only put one of the transformer, any of its transformers can all the load to bring all the general into the line breaker and bus in the breakdown of the circuit breaker, interlock between the three, A change vote, B variable can not vote, or vice versa, B cast A can not vote. This is the nature of the load mostly for a load, power supply is necessary for high reliability, but also the largest investment. Dual use can be divided into several, mainly refers to the change can be put into use, and some can be put into the parallel use, in some cases is not allowed to use in parallel, is the three circuit breakers with interlocking Three locks two spoons, three circuit breakers can only vote two. At the same time the capacity of the transformer is also different, some are prepared, some are dark spare, the specific use depends on how the original system design. hope this helps.
- Q: Parallel can provide the total capacity is not the sum of the capacity of the two transformers, or how to calculate? What is the principle of allocation of load load, that is, how to allocate two transformer load capacity?
- After the parallel capacity can be provided is the sum of the capacity of the two transformers ---- If the two transformers capacity is the same, after the parallel capacity can provide the total capacity of the two transformers are the sum of capacity. If a 1000kva transformer and a 800kva transformer in parallel, the parallel can provide the total capacity of 1600kva. The distribution of load load and what principles, that is, how to allocate two transformer load capacity --- transformer parallel to meet the three conditions: 1, two transformer transformer ratio equal; 2, two impedance voltage equal; 3, two Transformer capacity should be as close as possible, should not exceed 3: 1. To meet these three conditions in parallel, the load is evenly distributed to two transformers.
- Q: hello. I've been thinking about this long and hard. you see ever since I was 2 years old I've been collecting transformers figures and other items. now that I'm getting older I know I must let go. but its kind of hard when for the first 8 years of m life my transformers were all I had. and I know when we die we will leave these things behind. but it seems so hard to let go. so what would you do if you were in my sitiuationcause this is very hard for me and i'm lost. I know in heaven we will all be happy but it seems weird to me will I not remeber transformers?if anyone has any ideas that would be great thanks.
- it could be smart to sell them if you need money.
- 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: What is the SN on the transformer? What is the difference between it and the actual power of the transformer?
- Corresponding to the line of fire and the zero line, there is a L is the ground
- 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.
- if transformer has secondary rated for 12V 1A, it means that you can get 12VAC out and maximum of 1A. If you exceed the current you will cause transformer to overheat and eventually burn. It does NOT tell you that coil is 12 Ohm, it tells you that largest load (lowest resistance) that you can safely connect to this transformer is 12 Ohm. If you connect 10 Ohm, you are going to see larger current which will overheat and eventually ruin transformer. you can use ampacity tables to determine minimum wire size to carry current of some magnitude.for example for 1A you would need at least AWG28 for a bare wire in air (free air circulation). insulated wire will carry less because insulation has certain temperature rating that is lower than that that of metal, plus insulation prevents heat exchange so current carying capacity is derated. In general for 1A you would need AWG26 or thicker (AWG24, etc.).
- Q: i have read different forums explaining what really is an isolation transformer but unfortunately i am having trouble on grasping the main idea? please help, why do they say that isolation transformer can help a person being electrocuted even if he touches one of the secondary terminals??? how is that??? thank you
- you know, transformer passes AC only not DC. Isolation means here is the isolation from the mains AC out let. Once the mains input voltage is not there in the primary, there will not be any secondary voltage as well. Hence one will not be electrocuted once the primary winding is being disconnected from the mains.Hence you are isolated from live and neutral of the mains outlet.One still gets electrocuted, when touched in secondary terminal provided that the primary terminals are connected to the mains input.Only the difference is that he/she is not contact with the the mains input voltage(Outlet) of having live and neutral terminals.Now, briefly saying, you are isolated from the Live and neutral terminal of the mains outlet and hence you are not direct in contact with the live and neutral terminals which may cause the current circulation(Close circuit) from live to neutral via load or ie your body(if you touch the only even one live wire or faulty neutral) and then get electrocuted. Now in case of secondary terminals, if one touches one of the secondaries(Be ware of the High voltages and have Safety First) there is no neutral to get the closed circuit and wont get electrocuted.). But oe still will get electrocuted if the path is leaky. Again safety First.Thank you.
- Q: Transformer Uk = 4.5% What does it mean?
- The short circuit impedance of the transformer is related to many factors of the transformer. Such as transformer capacity, loss, internal coil structure and so on. But once the transformer is manufactured, it is the same. Short-circuit impedance is a very important technical indicator for the user. Such as the stability of the power supply system, the quality of the power supply, the transformer in parallel after the safety and reliability, and so have a relationship.
- Q: i have an epcos 565-2 transformer and i want to know how much it will raise the electrical output of a standard 1.5 volt battery. i really do not know much about transformers, but i bought a motor, assuming that i would be able to do fun things with it, and i hooked it up to all the power i could(solar batteries, and numerous amounts of AA batteries) but it wouldn't spin anything that i attached to it more than probably 60 rpm. i bought a transformer to boost the power, and spin the motor much faster. the motor is graded for 3000 rpm maximum, but i just want it to be above 250. any help would be appreciated.
- Transformers will only work with AC, not the DC from a battery. You will have to buy/build an inverter circuit to convert the 1.5 V to anything higher with a transformer (the transformer may become part of the inverter if it is the right kind). The other thing to think about is the power level. A 1.5 v AA battery is good for this much power: 1.5 volts * 1 Amp 1.5 Watts You might get 2 Watts out of it for a few minutes, but it can only sustain 1.5 to 2 Watts for about an hour. How much power is the motor rated for? If the motor is rated for 10 Watts, then 1, 2, 3, or even 4 AA batteries will not be enough to power the motor much above 250 RPM. There is still alot you need to know. Just for fun try a bunch of D cells in series (about 10 of them) The extra current provided by the D cells may spin the motor faster. .
- Q: I am going to see Transformers 3 today with some friends. Can someone give a detailed summary of what happens in Transformers 1 and 2 because i haven't seen them. Thanks to whoever helps.
