Q: High-rise residential basement transformer noise is too large, how to solve, whether the need to shift, there is no other way to solve! Thank you as much as possible! If you have to do this project also please educated us!: Transformer noise is mainly caused by magnetostriction of silicon steel sheet. method: 1, choose a reasonable magnetic density; 2, core clamping; 3, pad to take shock measures; 4, the tank within the parts fastening, does not allow loose metal parts or standard; 5, all the accessories on the tank must be tightened; 6, the use of low noise fan; 7, the installation of the basic level. Dry-type transformers do not have fuel tanks, remove the other 5, the same, because the dry-type transformers do not have the mailbox, the core magnetic choice, parts fastening, installation foundation leveling is more important

Q: I have just receive a gift from friends aboard. it is a transformer Universe Cyclonus with Nightstick. A Deluxe sized toy with Targetmaster partner.I have never heard about that. what is Transformer Universe? Is it a company similar as Takara Tomy?: Transformers: Universe is a Transformers comic series and toy line that introduced repainted versions of past figures. The Transformers: Universe toy line traces its origins back to when Hasbro imported the Transformers: Car Robots toy line from Takara and called it Transformers: Robots in Disguise. Although they made most Hasbro versions of the Car Robots characters, they also released a number of repainted molds from previous toy lines and released them as part of the Robots in Disguise line. When the Robots in Disguise line ended and Transformers: Armada started, the repainted product line was given its own title: Transformers: Universe. If you want to see more informations in detail, strongly recommend you to visit its official site or Yahobby online store for product list.

Q: As a small project I wish to wire a microwave transformer to create arcs in air via use of a wand (and yes I will be taking the necessary precautions but that's step 2) first I need to know a couple things: 1 on the high voltage secondary is it really as simple as take the two leads and put them anywhere near eachother? Would that not create a MASSIVE short circuit? Most of the tutorials I've seen use in series so perhaps that negates it in some way? Or am I reading it wrong? Is there some sort of safe load used? Or does it really arc to itself? And 2 what is a good way of preventing it from overheating (if that is a problem). This will probably be used as a Jacob's ladder or old motherboard destroyer. Thanks so much for the help!: Don't.

Q: I have a 240v-5v transformer for recharging, and it makes an annoying very high-pitched squeaking noise. What causes the noise?: Normal transformers with iron laminated cores operate at 50-60Hz (50-60 times a second), but transformers in modern cell-phone chargers and PC power supplies require a higher power than would be possible for the given size restraints. A 240v to 5V @ 1A 50-60hz transformer would be the size of a deck of cards and would weigh several kilograms, but if you replace the core of the transformer with a ferrite material (powdered iron) and switch the primary winding at high frequency, say 20Khz or more (20 thousand times a second) the size of the transformer shrinks to the size of a small coin. The ringing sound you are hearing could be caused by several things: 1. It's operated at a near-audible frequency, like 19Khz (not very likely) 2. It's under very high load condition and it's struggling to meet the power requirements and as a consequence the duty cycle of the PWM has increased which can make a chirping sound. 3. It's defective or dying, and it's having a hard time regulating the output voltage and it's excessively modulating the PWM. 4. You are young and young people have better than normal hearing in the higher end of the frequency range and you might be hearing a harmonic of the higher than audible drive frequency. Hope that answers your question :)

Q: What is the critical load of the economic operation of the transformer?: In order to increase the amount of active loss caused by the active loss of the system in the power system, a conversion factor is introduced, that is, the reactive power economic equivalent. Reactive power economic equivalent, is that the power system to send 1kvar reactive power, the power system will increase the number of active power loss kw, the symbol kq, unit kw / kvar. This kq value and the power system capacity, structure and calculation of the specific location and other factors. For the factory substation, reactive power economic equivalent kq = 0.02 ~ 0.15; Kq = 0.05 ~ 0.08; for the three or more transformer factory, take kq = 0.1 ~ 0.15 ~ 0.04; for the two-stage transformer factory, take kq = The

Q: about transformers: Leaving aside the double negative, the problem is your use of cancel - what do you expect - that it will go back to the generator and kill it? The transformer produces an output voltage which tries to do work against a resistance or inductance - the work it does produces a back EMF which the supply voltage works against so the generator has to do work. If there were no EMF in the primary, it would behave like a short circuit and blow the circuit - which is does in a small scale in the starting surge that you have to allow for when turning on equipment.

Q: im building a step up transformer and im wondering if a 10:130 turn ratio would give me the same results a 100:1300 turn ratio. my specific questions are:1) Would i get the same power boost?2) If not, would it be similar or close to it?3) If not, why not?: I assume your question refers to an ideal transformer. The turns ratio is the turns ratio. 10/130 100/1300. A transformer won't boost the power since the power in power out. If it's a step-up transformer, the voltage is increased on the secondary side compared to the primary side by the turns ratio.

Q: A 2300/230 V step down transformer is rated at 70 kVA and 60 Hz. Its windings have the following resistances and inductances : Rp 0.093 ohms, Xp0.280 ohms, Rs 0.00093 ohms and Xs 0.00280 ohms. The transformer's rated current at the secondary is 3261 A. Assume that a10 from 2300/230 V and calculate the no load voltage for unity 0.7 lagging and 0.7 leading power factor.: You question does not make sense. First issue: You want to calculate the no load voltage? At the secondary? But you specify a power factor? The only possible interpretation that can be drawn from a specification of power factor is that the transformer is under load. Second issue: You specific primary and secondary winding resistance and inductance. The problem is to calculate open circuit (no load) secondary voltage. But the specification says nothing about the core. If the transformer is open circuited, there is no secondary current, and therefore no voltage drop in the secondary winding resistance and reactance. And the specification says nothing about the core, the one must presume that there is no core loss. In the absence of core loss, and at no load, then there is no primary current, and therefore no voltage drop in the primary winding resistance and reactance. Third issue: what do you mean by a 10?

Q: a house's two furnaces are not working. the pilot lights are on. The lady's brother said there is no voltage at the thermostat. where does the 24 v come from? a transformer ? where?: There are two step down transformers either 208 to 24V or 120V to 24V. The transformer is marked what voltage its rated for and also can be verified with a volt meter. You need to check inside the furnace for voltage by removing the furnace panel. Try this turn the fan to ON on the thermostat. If the blower comes on your getting signal. And have 24V. Now if you have batteries in the thermostats then either the contacts are dirty or the batteries are dead. So check that as well. Also, if for some off reason you took the furnace cover off and did not put it back on right. There is a door switch. If the switch is not making good contact the unit wont do anything. Lastly if you have an older furnace that uses a fan combination switch that may be bad. Try running the unit with the fan set to ON and then turn the heat on. If the heat comes on then the fan combination switch is at fault and your on barrowed time till the high limit device fails.

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?: Well, I thought the movie was great. And yes, I think she was very pretty. I didn't see that her acting was as awful as everyone is saying. I think people were expecting it to be an Oscar winner, when really all you could expect was to have a good time watching the special effects and the robots beat the crap out of each other. Like, the first scene where Bubblebee and the cop-car battled that was thrilling people overlook that. I think, at least. Anyway, you already know my answer from a previous question about the movie. I thought it was great. I even saw it twice, and I see NO movie twice.
