Q:Transformer turns around the number and how much V is calculated: Transformer turns around the number and how many V calculation method: 1. Find the number of turns per volt: Number of turns per revolution = 55 / core cross section For example, the core section = 3.5 ╳ 1.6 = 5.6 square centimeters Therefore, the number of turns per revolution = 55 / 5.6 = 9.8 turns

Q:Current and Potential transformers both are actually Instrument transformers, which step down or lower down the values of current and voltages for measuring purposes.But I have heard of that both CT and PT specifically are used for stepping up current and voltages at some point of transmission system.if this is correct then can anyone tell where they are used?If not then there are step up transformers for similar uses but my question is why they are not called as CT's or PT's.: Assume the source is our normal house electric supply. Assume that the following loads will work safely for the two voltages. Case 1. The load is impedence type. Then Power is Voltage^2/impedence. Example is our heater load. Hence by manupulation of the impedence, we can manupulate the power output. Case 2. Assume it is a constant horse power motor load similar to our fridge. Adjustment of voltage will not alter the power output. The power output will be entirely decided by the load horse power. But an increase voltage will reduce the input current, there by reducing the heat loss in the load.

Q:I personally thought transformers was worse but very similar to the avengers.: I liked the Avengers more.

Q:Here we go I have 4 transformers (230V to 12V) and 4 radio receivers. I have one transformer connected to one receiver. Similarly all transformers are connected in the same way. Now, I used a connection box (normal heavy duty ones bought at hardware shop-i think its made of some kinda fibre) to house 2 transformers and 2 receivers. This scenario is happening in my roof. I went to open one of the box the other and the transformer was hot. It wasn't hot to the point of not being able to hold it. But hot enough for me to hold it for for a while before letting go. So the basics here is that one transformer is only powering one receiver which is OK for the load. But I am a bit worried as to whether this can start a fire in the roof. Any advice please? Can this scenario lead to a fire? (Even though there is no overloading): Not knowing the rating of the transformer and the actual load on them, all I can do is give you generic answers: a) Transformers have a rating which is the continuous amount of load it can carry without overheating. b) Typically, a transformer can handle momentary loads at 125% of rating - but that is neither a good idea nor always accurate. And momentary means just that - a motor starting, for instance. With that in mind, if a transformer gets warm to the touch, it is probably working within its range. If it is hot to the touch, it is being overloaded. The generic rule-of-thumb is that if you can touch the transformer indefinitely, it is OK. If you have to remove your finger/hand in less than 3 seconds, you are far into the danger zone. If you have to let go after any period at all, you are in the danger zone. Check the rating of the transformer and the actual load of the receivers. Now, when transformers fail, they typically do so in a fairly spectacular manner. The coils get very hot, the insulation (varnish in most cases) fails, and they begin to short inside - getting hotter as they do so until they eventually either blow a fuse, open, or melt down. It is the last that absolutely *can* start a fire. But before that happens, they often toast whatever is connected to them as well.

Q:What is the power transformer, what is the rectifier transformer: Rectifier transformer is isolated transformer, is often used in the power distribution cabinet to do the power.

Q:How was the video game Transformers: Dark of the Moon?: Transformers: Dark of the Moon is still an enjoyable game, but I don't think it's worth $60. I usually buy games at $20 and even then I was very glad that I just spend $2.15 to have rented this and even able to finish it and played some multiplayer in 2 days.

Q:I have halogen lights in my basement. When i mean contact i am talking about this little hanging jack where by you plug in the light bulb into. For some reason, one of my lights are not working properly but I have already tested the light bulbs out. I have a feeling that the contact/transformer (hanging jack slot) is ineffective. Does anybody have an idea how to change these things?: You are putting too much energy into the transformer. You need a circuit breaker in your circuit in order to reduce the amount of power that goes through the transformer. Because so much power is going through the transformer, it can only put out so much, so fast, and, therefore, your halogen lights are not turning it on. You can google circuit breakers or resistors, or take the lights in to any hardware store to see if they can fix them.

Q:A single phase transformer operates from a 230V supply. The primary and secondary resistances are 0.03 Ω and 1.12Ω respectively while the corresponding leakage reactances are 0.1Ω and 6.4Ω; the magnetising branch can be neglected. The secondary winding has four times as many turns as the primary. Calculate :i) The equivalent impedance referred to the primary circuitii) The secondary terminal voltage when the load has a resistance of 200Ω and an inductive reactance of 100Ω.iii) The secondary terminal voltage when the load has a resistance of 200Ω and a capacitive reactance of 100Ω.Can someone show me how to tackle this question please?: i) the secondary transformer impedance is 1.12 + j6.4Ω. Since Ns/Np 4, this impedance reflected to the input is (1.12 +j6.4Ω)/(Np/Ns)? 007 + j0.4Ω ii) Reflect the primary transformer voltage and impedance to the secondary side. 230(Ns/Np) (1.12Ω + j6.4Ω + (Ns/Np)?(0.03Ω + j0.1Ω ) +200Ω + j100Ω )I 920 (1.6 +200 + j8 +j100)I (201.6 + j108)I |Z| 228.7Ω √(201.6? + 108?) at angle of inverse tan (108/201.6) 28.18° I 4.02 amps at -28.18° 3.54 - j1.90 amps The terminal voltage is 920 - (1.6Ω +j8Ω)(3.54 - j1.90 amps) iii) solve 920 (1.6Ω +200Ω + j8Ω - j100Ω)I (201.6Ω - j92Ω)I The terminal voltage is 920 - (1.6Ω + j8Ω)I

Q:I will vote for the best answer based on the use of simple vocabulary, I don't know much about transformers so try to keep it as understandable as possible. I know it's not a simple subject, thanks!: Interesting topic!

Q:I wanted to watch the transformers cartoons but because there is so many I don't know which to watch first, seconds etc.Can you please tell me in order which to watch?I'm watching Transformers Season 1 episode 1 atm.THANKS: The original series, now called Generation One, ran for 99 episodes from 1984 to 1987, with a feature film released taking place between Season Two and Season Three. There were a number of series produced exclusively in Japan, picking up from the end of Season Three and ignoring Season Four (Rebirth, Parts 1-3). These are Headmasters, Masterforce, and Victory. These are ignored by American productions, however. Generation Two is the same as Generation One, only spruced up a bit with computer graphics. Beast Wars is the second Transformers series produced in the States, and borrows elements from both the original G1 cartoon and the G1/G2 comics produced by Marvel. The next series, Beast Machines, is a direct sequel. You don't need to see G1 to understand BW/BM, but you do need to see BW to understand BM. After BM, four Japanese-produced series totally unrelated to G1 were imported to the US. Robots in Disguise was the first - unfortunately, it doesn't have a DVD release in the States. You don't need to have seen any previous Transformers series in order to enjoy this one. The next three series (Armada, Energon, Cybertron) together constitute the Unicron Trilogy. In theory, they all fit together - in practice, there are serious disconnects, especially between Energon and Cybertron. Blame Japan. The live action films, again, don't require a viewer to have seen any previous material. The most recent animated series is Transformers Animated. Again, you don't need to have seen any previous material in order to enjoy this program. So yeah, doesn't really matter what order you watch them in - just use the production order as a guide for watching individual episodes, and you should be fine.
