Q:An AC generator, originally designed to provide a peak output voltage of ± 155 V at a frequency of 60 Hz, is required to provide a peak output of ± 340 V at 50 Hz. If the generator is connected to a transformer with 200 loops in its primary coil, how many loops should there be in the secondary coil in order to provide the required output?Using the formula Np/VpNs/Vs I get 439 coils, but this is too easy for a 6 mark question and doesn't include the change of frequency. I have no idea what to do and need some help :(: Your answer is correct. The frequency has no effect on the turns ratio. The frequency does effect the required primary inductance, however. More turns with 50Hz, about 20% more for same magnetizing current as with 60Hz. I am assuming your generator can change frequency.

Q:Transformer Transformer Principle: Summary of words: Electrosagnetism. Magnetic electricity. Its basic principle is: a coil and the secondary coil around the same core, when a coil power, the alternating magnetic flux in the core, (magnetism) the alternating magnetic flux through the secondary Coil, according to the law of electromagnetic induction, will produce alternating electric potential in the secondary coil, (magnetic power) due to a secondary side of the coil turns, therefore, the secondary side of the voltage will not wait.

Q:anyone else see the trailor for this movielooks kinda goodthough, it may be were the transformers are bad guys, i dunno: transformers is a classic. of course everyone should go see it.

Q:A 120 kVA, 7000/277 V (What does this rating mean) distribution transformer has the following resistances and reactances: Rp 5.5 ohms Xp 6.5 ohms Rs 0.007 ohms Xs 0.008 ohms Rc 55 kohms Xm 15 kohms The excitation branch impedance are given referred to the low voltage side of the transformer: a) What's the equivalent circuit of the transformer referred to the low voltage side b) What's the the per unit equivalent circuit c) Assume that this is supplying rated load at 277V and 0.89 lagging power factor, What is the transformer input: 120 kVA, 7000/277 V (What does this rating mean) Primary voltage rating: 7000 V, secondary voltage rating: 277 V, rated load: 120 kVA It is unclear whether this is a single-phase or three-phase transformer. You probably need to assume it is single-phase. The equivalent circuit of a 3-phase transformer is analyzed as one of three single-phase transformers that could be connected to make the equivalent Y-Y three-phase transformer. The secondary voltage, 277 V, is the line to neutral voltage for a 480 V, wye distribution system. That is a USA standard system voltage. The primary would be 12,124 V L-L, 7000 V L-N. That would a reasonable primary distribution system voltage. Referring the circuit to the low side means changing the primary component values to the equivalent secondary values and moving the ideal transformer to the primary side of the circuit as shown below. To change the primary impedance values, multiply by (Sec V/Pri V)^2.

Q:Rules for the operation of cooling devices for oil - cooled transformers: A, cooler should take their own independent dual power supply, and can automatically switch, when the work of power failure, automatically put into standby power, and issued a sound signal; ?B, the transformer upper oil temperature reaches 55 ℃ or the current reaches 70% of the rated value, the auxiliary cooler automatically input;

Q:I think the power supply to my external hard drive has failed. Is there anyway I could replace the transformer. There is no way to contact the manufacturers as they have the worst customer services ever (Formac). I have emailed them 5 days ago without a reply.: Im assuming you are just talking about a plug in adapter with the transformer built in. If you look on the face of the transformer pack it should give you a VA rating and a voltage rating. You can buy a new one as long as you match the numbers. Hope this helps.

Q:im doing a power point and i want to know all i have is that it got started in 84', but who owned it at first and who ownes it now and is it a product? but basically i need a site or a person to tell me how it got to now and i need a site that has nice pics of the first transformers to 2009: Yep, it replace into an 80's comic strip placed out with the help of way of the Hasbro company company company,(who additionally advertised the everyday GI Joe toys and cartoons). The exhibits have been long working commercials for the ever evolving line of toys. The Transformers have been the form till Hasbro have been given right here out with the previous Transformers action image (anime) which pissed each and all the fams off by using fact of certainty they killed off Optimus precise and then dwindled the numerous characters into obscurity with the objective to sell their new line of robots. you will are available the process most of the previous episodes on youtube.

Q:I have to build a transformer which are the main formulas or some source that explains this: You need to specify what the transformer is to be used for. (why do you have to build a transformer ?) (the characteristics of the core are critical to the design) Until you specify that, only the simplest of basics relating to turns ratios can be stated: 1 - Power in primary Power in secondary 2 - Voltage ratio turns ratio 3 - Current ratio 1 / (turns ratio) [from #1 #2] 4 - Impedance ratio Turns ratio squared. [ from #2 #3] **IF** it is a power transformer, I suggest getting a transformer with the same, or slightly higher POWER rating, then simply re-wind the secondary using #2 above. (I did) or Google: how to design transformer windings then pick the one that suits your needs best.

Q:What is the transformer absorption ratio (R60 / R15): Absorption ratio = R60 〃 / R15 〃 For the same insulating material: the moisture or defective absorption curve will change, so you can determine the insulation curve based on the insulation is good or bad, usually in megger in 15 seconds and 60 seconds of the insulation resistance ratio (This is the absorption ratio, expressed by the K value), because the insulation of the degree of moisture increases, the leakage current increase than the increase in the starting value of the absorption current is much more, expressed in the insulation resistance is: megger in 15 seconds and 60 seconds of the insulation resistance is basically equal, so the K value is close to 1; when the insulating medium is dry, because the leakage current is small, the current absorption is relatively large, so the K value is greater than 1. Experience: When the K value is greater than 1.3, the insulating medium is dry, so that by measuring the absorption ratio of the insulating medium, it is possible to determine whether the insulating medium is damped and K is a ratio which eliminates the geometric dimensions of the insulating structure , And it is the same temperature measured under the value, without going through the temperature conversion, the comparison of measurement results is very convenient.

Q:Do not all change the pressure? What is the difference?: The inverter is a DC power supply into AC power, and the transformer is a kind of electromagnetic induction principle to achieve the electrical conversion of electrical equipment, it can be a voltage, current AC power into the same frequency of another voltage, current Of AC power. Simply put, the inverter is an electronic device that converts low voltage (12 or 24 volts) of DC into 220 volts. Because we are usually 220 volts AC rectifier into DC to use, and the role of the inverter in contrast, hence the name. We are in a "mobile" era, mobile office, mobile communications, mobile leisure and entertainment. In the mobile state, people not only need to be supplied by the battery or battery low-voltage direct current, but also need our daily environment indispensable 220 volts AC, the inverter can meet our needs. Transformer is a kind of application of electromagnetic induction principle to achieve electrical energy conversion equipment, it can put a voltage, current AC power into the same frequency of another voltage, current AC power. The role of the transformer is to change the voltage. Can be issued by the power station to rise to high voltage, in order to reduce the loss in the transmission, to facilitate long-distance transmission of electricity, you can also place the electricity, the high voltage will be reduced to the voltage, to the user. Therefore, the transformer in the grid is in a very important position, is to ensure safe, reliable, economic operation and people's production and life of the key equipment.
