Q: I have a bulb that currently uses a 120V primary to 6V secondary transformer. The load is a 30Watts. I would like to know what transformer I could use to power 8 bulbs (6v 30W each) ? Thanks. How can I calculate that?: Assuming you wire the bulbs in parallel. You need a similar transformer (6v secondary) but one that is rated at 240 watts (or a bit more), 40 amps. Note that the current will be 40 amps and will need quite a heavy wire, #4 or 5. You could also put the bulbs in series, and would need a 48 volt secondary, still at 240 watts. You would have problems of any series string, if one bulb goes out, they all go out. You can also use parallel series combos, 3 pairs, or 2 strings of 3 each as a compromise. edit. Later thought of another alternative that may help. Get a transformer with a 12vCT 240W secondary. Wire like you would 2 phase house wiring, 3 bulbs to each outside terminal, and all 6 to the CT. This means the wire only has to handle 20 amps and can be smaller, and you will not have the series string problem. 12VCT transformers are fairly common. Or if you can find it, and the wiring is still a problem, get a transformer with 2 secondaries each of 12VCT at 10 amps.

Q: How long does it take to restart the transformer?: What are the requirements for the commissioning and outage of the transformer? A: (1) the new operation of the transformer must be rated voltage under the impact test 5 times, overhaul after the impact test 3 times. (2) the transformer put into operation when the first cooler, cooler running for a period (about 15min) time, until the oil temperature is no longer rise and then stop. Disconnect the transformer first. (3) 110kV and above in the neutral point direct grounding system, put into operation and outage transformer, the operation must be grounded before the neutral point, after the operation and then decide whether to decide whether to disconnect. Transformer neutral point access to the arc suppression coil should be first after the exit. The neutral point of the two transformers should not be connected to a neutral bus with an arc suppression coil.

Q: i have learnt from engineers that welding transformer is different from power transformer. welding transformer's current will be high.but its load will be low.my actual doubt is current is always proportional to load.then how we can justify this logic that welding transformer's current rating is high and its load is less.: The power transformer is used for transformation of electrical power from one circuit to another but welding transformer is used for obtaining the very high current at secondary windind for melting the metals of different types for welding INZMAM SIDDIQUI

Q: Hello, I am using a spark transmitting system that will throw about 40KV at about 5MA. I need to step this way down. What rating should I look for? If a current transformer isn't the way to go, please tell me what I should doThanks in advance: Current transformer coupling the 40kv line then produce about a few hundred volts depending on how many turns existed in the current transmitter. It needs many such transformers to do different step down. If you require over 5kv per step,current transformer coupling might not be the best way. The better way is control the high voltage 40kv source.Vary the supply source shall do.

Q: How to test the transformer capacity: If the temperature rise of a transformer is less than 55 degrees, it can be considered to achieve the design capacity. ? As the temperature rise test time is long, the customer can not track the whole process, some bad transformer manufacturers in which mischief, cut corners, made the transformer can not reach the design capacity.

Q: A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil.A How many turns of wire does the secondary coil have?B When the transformer is running at full power, what is the current in the secondary coil?C The current in the primary coil?I know what equations I would use, but I don't have enough information to use them. Can someone at least set these up and show me how to plug the numbers I have into the correct equations?: A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil. Power output Power input Power Volts * Amps 350 13,000 * amps Amps 0.0269 amps current in the primary coil? House voltage 120 volts 350 120 * amps Amps ≈ 2.92 current in the secondary coil? Amp Ratio 2.92 ÷ 0.0292 100 : 1 Wire ratio 100 : 1 A How many turns of wire does the secondary coil have? 50,000

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 want to get the asus transformer, and on the web, there is stuff like asus transformer prime, and i want to know the differences between both and the negatives and positives of each. Asus transformer prime is $100 more than the asus transformer, so I want to know if it's worth it or not. Thanks!: Yes the transformer is different and older than the transformer prime. It has NVIDIA Tegra 2 processor vs the tegra 3 in the prime. Tegra 3 is a quad core 1.3 ghz processor and the tegra 2 is a 1ghz dual core. You should definitely get the prime but dont buy it yet. ASUS sold out the first batch which had a few issues, and they are releasing the bugs fixed second batch soon with Android 4.0 Ice Cream Sandwich pre installed (I could be wrong here), so wait till then and buy it with the keyboard dock which doubles the battery! I'm waiting for the prime to come out soon too! It is very thin and thinner than the galaxy if not the same. Hope this helped.

Q: There are lighting transformers, tires and disassembling machine transformers, there is an electromagnetic starter, the tire changer transformer will always burn ah, are used 380V transformer, I have measured the next, when the transformer transformer measurement 391V, electromagnetic Starter average is 396V, nothing to have, has been used very well. But the tire disassembly machine transformer to die, the average voltage of 396V, installed up a few seconds to very hot, but why the other two no matter? Put away Tire disassembling machine Transformer I alone load the air switch voltage ah, 396V, only more than 10 V, the other transformers are not any problems If there is no problem with the secondary side, the voltage reaches the number of volts, the transformer will quickly become hot PS: 396V I was in the 380V where no-load test ah, more than 10 volts are not ah: And voltage has nothing to do with a few seconds to install very hot, the secondary side must have a short circuit fault!

Q: i just got back from seeing transformers and the special effects were awesome but the storyline could have been better. I thought the girl meghan fox was so prettywho thought the same?: my take was, if you're a decepticon, why give away anything until you're ready to strike? think about it, you're an a**kicking supercomputer with crazy weapons and you can hack the sh** out of the most sophisticated systems on this planet in a matter of seconds. you're looking for a seemingly insignificant pair of glasses WHICH ARE FOR SALE ON E-BAY. you can't just hack a bank or large corporation, jack a few million, and give the high school junior a huge amount of money for the glasses and just wait a day for UPS, THEN go for Megatron and the All-Spark? that was the big one for me, also they put too much comic relief on the transformers side. that version of soundwave they put in there was way too cutesy. and sorry dude, but Meghan Fox is just Jennifer Connolly ten years ago, but without the great skin. don't get me wrong, i thought the movie was decent enough, but people are going crazy over it, and it's unwarranted. that's all i'm saying.
