- Q:I have a doorbell that quit working. I don't know how to tell if it is the bell or the transformer
- Verdugo: go to the transformer and check for power coming out you should get a 24 volts dc. Then, check for power across the switch you should get the same, then check for power at the bell. If you have power at the transformer and not the switch then re-wire the system. The key is having power. If you have power at the switch and nothing happens when you press on the switch and you do have power at the door bell when you press the switch then the bell is bad. That simple. Just follow the circuit. and just comdem where it stops. you can also check for continuity at the switch. if you don't get any signal when you press on it. the switch is bad.
- Q:Transformers, broken, how to repair
- You can first check the insurance, if only insurance problems, you can short-term insurance; the other can buy a replacement of the same specifications, the coil can also be broken coil rewind.
- Q:i have been looking at transformers and i wanted to know a few things. will they do dc current? do they just add x amount of volts or do they multiply by x or just change to x? also there is a sort of container that goes around them is that carbon???? it goes all the way around and then through
- will they do dc current? No o they just add x amount of volts or do they multiply by x or just change to x? A transformer does not give you power. what it does is change the voltage in an inverse proportion to the current ( you get more voltage, you get less current) also there is a sort of container that goes around them is that carbon? They can be, most of the time it is steel though. unless you work at a power plant or sub station, then you might see some transformers that have carbon cases.
- Q:What is the transformer through the full and half through the problem, the definition of a little more, the best reference, or sent to my literature.
- (3) split impedance: two short-circuit between the low-voltage winding impedance, that is, high-voltage winding open circuit, a low-voltage winding short circuit, another low-voltage winding power supply when the equivalent impedance. Where the reactance component is called split reactance.
- Q:i need to have an immediate answer (solution to this) thanks:Determine the transformer bridge rectifier and filter capacitorspecifications/values required to produced an output current of 3A and a nominaloutput voltage of 17VDC with a ripple voltage of 2 Vpp. Assume a line voltage(from Meralco) of 220VAC, and that the design is to use a center-tappedtransformer.2. Given the characteristics of the raw DC supply just designed, determine thecomponent values of a transistor regulator circuit (based on “Simple TransistorVoltage Regulator Circuit” from the CCS1
- If you want to step 12 volts AC to 96 AC, you need a transformer with a primary to secondary winding ratio of 8. You then connect the 12 volts to the secondary, and will get 96V at the output. The most accurate way to do this, is go to a transformer shop and ask them to do this. They will ask you for current requirements. If this is not an option, go to a hardware store and ask for a 120V to 15V (or whatever value is closest) transformer. Keep in mind that while voltage is multiplied, current is divided, so that at the end you get the same power. So, if you have a transformer with n8: V12*896 volts I 110/813.75 amps
- Q:Power transformer parameters
- B. Transformer efficiency: In the rated power, the transformer output power and input power ratio, called the efficiency of the transformer, that η = (P2 ÷ P1) x100% where η is the efficiency of the transformer; P1 is the input power, P2 is the output power. When the transformer output power P2 is equal to the input power P1, the efficiency η is equal to 100%, the transformer will not produce any loss, but in fact this transformer is not the transformer transmission power always produce loss, this loss is mainly copper Loss and iron loss. Copper loss is the loss caused by the transformer coil resistance.When the current through the coil resistance heat, part of the energy into heat and loss.As the coil is generally wrapped with insulated copper wire, so called copper loss. The iron loss of the transformer includes two aspects: First, the hysteresis loss, when the AC current through the transformer, through the transformer silicon steel wire magnetic field its direction and size changes, making the silicon steel sheet internal friction, release heat, Part of the energy, which is the hysteresis loss. The other is the eddy current loss, when the transformer work, the magnetic core lines through the line, and the magnetic lines perpendicular to the plane will produce induced current, because the current self-closed loop Circulation, and into a spiral, so called vortex. The presence of eddy current heat, energy consumption, this loss is called eddy current loss. Transformer efficiency and transformer power levels are closely related, usually the greater the power, loss and output power is smaller, the higher the efficiency, otherwise, the smaller the power, the lower the efficiency.
- Q:Can a transformer having a given VA rating at 50Hz handle more power at a higher frequency, say, 300Hz or 400Hz?I want to build an inverter to run an 11 watt compact fluorescent lamp. Since these devices rectify the supply directly, there does not seem to be any good reason to feed the lamp with 50Hz.If my understanding is correct, the core has to be able to store up to one half-cycle's worth of energy in the magnetic field (which will then be released out of the secondary winding in the form of electricity) to avoid going into saturation and overheating. So at twice the frequency, it should be possible to push twice as much power through for the shorter half-period without saturating the core. (Actually, probably a little less than twice as much, as there will be more resistive heating; but transformer wire is often slightly thicker than it really needs to be, just because it's less likely to break in the winding machine.)So can I over-run a transformer this way, or is there some gotcha that I've missed?
- The equation V 4.44fNaB determines what is required for a transformer to avoid saturation. V is the voltage, f is the frequency, N is the number of turns of wire in the winding, a is the area of the core, and B is the peak magnetic flux density. The transformer has presumably been designed so that the peak flux density is as high as it can be without saturating the core. For an existing transformer, V/f a constant. If you increase f, you can increase V so that V/f remains constant. However, the hysteresis losses increase in proportion to the frequency increase and the eddy current losses increase in proportion to frequency squared. In addition, skin effect will increase the copper losses at higher frequencies. Reducing the copper losses by reducing the current would compensate for the skin effect. Reducing the copper losses would tend to compensate for the increased iron losses, but it is hard to say how much a cooler coil will compensate for a hotter core.
- Q:Go transformers
- I have to go for Transformers. Being totally unbiased - never been a fan of Spidey or Transformers, I was awestruck by Transformers. Spiderman 3 was good too - but failed as a total packaged. It was too long and I was aware that it was too long and that's the reason it lost me (unlike Pirates 3 -which was long too but it kept me interested - but Pirates 3 is not part of this question) Yeah! Go Transformers!
- Q:i need a 120VAC to 160VAC step-up transformer; like, not an already built converter, but a just bulk single transformer. where can i buy one?and don't say go look in OKorder, coz i've already looked and there isn't any
- Need to know the current rating, or the wattage rating. also look for a 40 volt step down, as you can use the isolated 40 volts to add to the 120 volts from a simple isolation transformer to get 160 volts keep searching. One alternative is to get a 120 to 240 transformer, and remove some of the secondary turns to drop it down to 160 volts secondary. This size transformer is very common and comes in all sizes, for all current levels. another alternative is to get the 450 volts DC that I think you want in a different way. Use a tripler on a 110/110 volt isolation transformer, which gets you about 460-470 volts. Or be elaborate and use a doubler on a 110/220 transformer with a regulator to drop down the voltage. .
- Q:Transformer tap adjustment there are several ways? What are the advantages and disadvantages?
- Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
