Q:How many transformers are used in a hundred households?
In accordance with the current design standards, high-end community, each household 30kW; mid-range community, each household 15kW; ordinary community, each household 6kW.
Q:Can the transformer be replaced with a component?
If you say the transformer is a small power frequency transformer, then you can use switching power supply instead. If the substation with high-power transformers, there is no thing to replace.
Q:If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts?
There is actually a phasing to the transformer windings. If you connect them in series with the phases adding (both hit + 12 at the same instant) you get 24 volts out. If you connect with the phasing wrong (one hits +12 while the other hits -12) and put them in series the output will be zero volts (and they might overheat). If you connect them in parallel with the right phasing you will get 12 volts and the amperage will add to give you the sum of their amperage. If you connect in parallel with the phasing wrong you will get zero output voltage (and the danger of overheating). If the transformers do not make their phasing clear put a voltmeter on the output and briefly turn on the primary while seeing if you get zero or the voltage you want. If the phasing is wring swap the wires of one transformer around and check with the meter again.
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:i have a transformer and i dont know anything about it. can someone help me with it.ps: i dont know how many turn the transformer have. dont the voltage either
_IF_ the toroid replaced into under pressure out to function off 50-60 Hz, and you are able to grant a prevalent transformer which will grant a similar AC output (the two voltage and modern means), then it is going to artwork. even nonetheless, if that toroid is a factor of a switching ability grant, then a prevalent transformer won't artwork. So the question maintains to be, is there an number of digital factors under pressure out around this toroid? if so, then you somewhat could desire to acquire a sparkling toroid, or in case you have a large style of time on your palms, rewire the prevailing one. (diploma and eliminate latest twine, noting their association and counting the turns as you circulate). If the toroid is meant to artwork on 50-60 Hz, then you somewhat ought to have some situation getting a prevalent transformer to greater healthy interior the lamp, yet i think you are able to make it exterior and placed it into this is very own container, equivalent to a modular grant.
Q:Find full load current of transformer. What do it mean by full load current? 100% efficiency, or maximum load in secondary winding?Let R1 32ohm, R20.05ohm, X1 45ohm, X2 0.06ohm.1 is in primary and 2 in secondary winding.R0250kohm, Xm 30kohm(R0 and Xm are the values refered to primary)How to calculate the full load current?
there are many criterion it is application dependant or power it is the load that causes a temperature rise that if loaded beyond it will cause failure of course it depends on the insulation material so a smaller transformer could have a much higher rating because it can stand more heat small electronic stuff will generally be when the transformer can no longer sustain the output voltage Anita
Q:50kva transformer price
2, Transformer (Transformer) is the use of electromagnetic induction to change the principle of AC voltage 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.
Q:Can somebody please help me understand this problem and help me do it? I'm having a hard time with it and help would be greatly appreciated.The following test data were obtained from short-circuit and open-circuit tests of a 50-kVA, 2400-600 V, 60Hz transformer.Voc600V Vsc76.4 VIoc3.34 A Isc 20.8 APoc 484 W Psc 754 WDetermine:A) the equivalent high-side parameters;B) RegulationC)efficiency at rated load and .92 power-factor for lagging.
read material regarding transformers Not just once but say 5 times, till you understand what is said. the transformer has copper loss due resistance of primary and secondary. It has additionally iron loss. The equivalent circuit is a sort of representation that brings in these losses. generally you can apply a low voltage to primary till shorted secondary has a current equal to less than rated current. These measurement details are given. Similarly open circuit measurement details are available. With understanding of how the rest can be calculated using worked examples in texts, you can solve it yourself. attempt this See Lee's book on transformers or schaums series on electrical engg.
Q:Could someone please explain, in relatively simple words, how an electrical transformer works?

Q:Electrical Machinery, Electric Machines, 3-phase transformers
Generally if you see three single phase transformers all mounted on one pole( not sure what a hydro pole is?), they are connected to supply three phase service to the customer. Not usually three single phase services, at least in the USA. The three single phase transformers may supply 208Y/120 volt 4 wire three phase, 120/240 volt 4 wire three phase (usually one of the transformers in this configuration is larger than the other two), 240 volt three wire delta or 480 volt delta, or a 480/277 volt 4 wire service., And on and on. This is determined by the voltage ratios of the transformers used and what the local utility supplies as a normal service voltage. Hope this helps, Newton1Law
