4. Reference Picture:
- Q: I am powering a lighting system with a mixture of SCR dimmers and HID lamps. I am pulling approx 285 amps/leg at 120/208V through a 150 kVA transformer. The 120/208V service coming from that transformer is indicated to be 400A/leg, but it seems to get pretty hot at 285A.
- Three phase transformers are given a power rating which is the sum of all three powers on each phase. So 285 amps on each phase at 120 line to neutral (assuming this is how youve them connected) is about 35kva, so about 100kva all up. What is actually on the name plate of the transformer? How hot is 'pretty hot'? Is it running as it was desinged (oil, dry, forced air cooling etc). Also how are your lamps/dimmers wired? The other answer is correct, the dimmers will produce alot of harmonics. The meter your are using to read the current is most likely designed to read a 60hz sine wave, any other stuff there will cause a wrong reading (they usually measure the average value, then apply a correction factor to obtain the rms value. But this factor depends on the wave shape, if its not a sine wave it will be wrong). See if you can obtain a meter that will measure the true RMS current. Transformers of that size are usually heavily over engineered, it should be fine as long as the tempertature doesnt continue to increase, ie to the point where the case is too hot to touch. As the other answer said it is probably rated for continuous operation at about 75 degrees. Id not worry too much as long as the temperature doesnt continue increasing.
- Q: According to your measurements when we have a step-up or a step-down transformer?
- A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF) or voltage in the secondary winding. This effect is called mutual induction. If a load is connected to the secondary, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the transformer to the load. In an ideal transformer, the induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp), and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np) as follows:- Ns/Np Vs/Vp ---------------------(i) By appropriate selection of the ratio of turns, a transformer thus allows an alternating current (AC) voltage to be stepped up by making Ns greater than Np, or stepped down by making Ns less than Np.
- Q: 1000KVA transformer power loss is how much
- Transformer no-load plus stray loss is fixed, usually 6% of the total capacity, load loss that is copper loss, according to the load power, and power factor calculation
- Q: I Watch Transformers,But Alot Of People Seem To Hate It.
- they are robots in disguise It seems sneaky why are they hiding? also the animationsucks it was from the era of crappy animation and based on selling toys after warner brothers and before ren stimpy and recent computer done stuff.
- Q: How to tune to 14V? Why I tune the value of the above voltage meter has been always beating.
- The above two parameters can also be extended or reduced by the ratio. Other parameters can be considered, as shown below.
- Q: Here's photos of the transformer in question. My dad pulled it put of some electronic he can't remember what and has had it sitting on the garage. Recently I've been working with high voltage and he pulled this out for me to work with just having trouble figuring it out
- First of all, never assume anything! There are some standard colour codes for transformer wiring, but not all transformers conform to the standards. In practice, a manufacturer can use any colour wire for any purpose, leaving you and me and a lot of other people wondering for all time, which wire is which? The measured DC resistance does not tell you anything about the AC voltage rating of any winding. With most power transformers, if there are two solid-black wires, they are the primary. If it is tapped, or there are two primaries (such as in dual-voltage units), there will be three or more primary wires (and possibly as many as 8!). I think the side with 115V on it is probably -- mind you, this is not for certain -- nothing more than the side on which that number happened to be stamped. So of course you want to know what to do next. Considering the number of wires and the ways in which they are connected, it would seem that an experimental method will be required. The 2006 ARRL Amateur Radio Handbook (and possibly other editions) tells how to figure out what's what with transformers. I strongly recommend using the procedures described therein.
- Q: i have a flyback transformer that i want to make a tesla coil out of and i need a diagram for the wiring configuration.
- The modern flyback transformer is also used to generate the DC operating voltage for the TV set. You have a lot more wires than you need to use. You need to get a copy of the wiring from someplace like a Sears repair shop and hope you don't have a built-in high speed diode and filter cap in the same package. The last thing you need is to try to run your Tesla coil from a DC source on the primary. I believe Ramsey electronics makes a package Tesla kit that runs off a flyback. Your coil will not produce a very large brush discharge but it should be a good demonstrater which will have a safe, low current spark.
- Q: I would like to use this circuit to power arrays of high power LED'sI understand the properties required to power LED'sI have beginners knowledge in electric circuits and have done some research on this circuit. I have come across several posts stating it is dangerous to connect this circuit straight to mains power. I don't understand is what makes it is so dangerous?AndIf possible, how can it be made safe without using a transformer.
- Your circuit will be fine without an isolation transformer if you connect a fast blow fuse, with the same current rating as your diodes or a bit less in the hot line to your voltage source. Your electric shock hazard is increased slightly without the isolation transformer. Your LEDs are vulnerable to power line spikes, even if you have an isolation transformer, but perhaps the transformer helps a little. An MOV rated about 190 volts in parallel with C, may provide some protection for your LEDs if the LED operating voltage is a bit less than 190 volts. Other MOV voltages are available at least rarely. Several hundred micro farads for C also suppresses spikes not only or your LEDs but also for other devices, connected to your ac source. A large value for C however means your diode bridge should be rated 25 amps or more.
- Q: how to calculate the secondary current of the transformer for example 1200 amps in primary ,primary voltage is 220kv and the secondary voltage is 34.5 kv of the transformer .
- For an ideal transformer, the voltage ratio is set by the turns ratio, so the transformer is a stepdown with the ratio of 220/34.5. The current ratio is also set by the turns ratio, but current goes up as voltage goes down, so the secondary voltage is 1200 x (220/34.5). Again, for an ideal transformer only.
- Q: i would say transformers alll the way
- Thank you!!!! :D Definitely Transformers. Even the second one too. The second one was even better than the first one. The first Transformers will blow both Twilight movies away combined! Hehe, sorry I love Transformers I'm sick of hearing about that Twilight franchise:P
