Q: i think transformers: Simpsons for sure:]

Q: How can we figure out which side of transformer is primary which one is secondary by measuring resistance ? I know that the side where input or supply is provided called primary from where the output is collected is called secondary side in both step-up step down transformersAnd, how can we troubleshoot a bad or a good transformer by measuring its resistance on both sides i.e. primary side secondary side ?thanks: While you can try measuring winding resistance on both the primary and secondary sides of a transformer with a digital voltmeter or an older volt ohm meter, the value is so low a fraction of an ohm most meters can't measure it correctly. What you can do is look for different wire sizes, the step down transformer will have larger diameter wires on the secondary side of the transformer ( smaller AWG) than on the primary side (larger AWG). A step up transformer will have larger diameter wires (smaller AWG) on the primary than the secondary. Again it is almost impossible to use an ohm meter to determine if either the primary or secondary winding is shorted. This is most likely found by applying power to an unloaded transformer and measuring the excessive current draw.

Q: A I have a 230V/12V, 3A step-down transformer. What will happen at primary side of transformer if I attach a 12V/5A device at secondary side? Will primary side attributes (such as voltage or current) change?: the transformer converts Watts if it is rated at 12V 3A it means 36 Watts if you load-it more than that it will overheat and eventually burn the primary current is proportional to the secondary current however with an overload of 5 A as oppose to a load of 3 A it may last for several hours before becoming too hot the answer is yes you can run your load for a while provided that you monitor the temperature and watch the situation however do not load over 3 times the rating (8~9A) for any length of time more than 1 second A

Q: What is the vacuum impregnation of the transformer?: To complete the winding and core assembly of the transformer, into a special dipping tank, the first vacuum, then open the lacquer,

Q: Distribution transformer: Not sure what you are asking. Transformers are wound for the best magnetic coupling possible to keep loses to a minimum.

Q: Are there any transformers action figures that arent for little kids like from the movie and are collectables? LINKS?: I used to play international of Warcraft. I remember being point 60 (the max on the time), and looking after agency in Ironforge. It replaced into annoyingly effortless to have low point newbs whisper me with, Gold Plzzz!!! and i desire 2! and am i able to have some gold? It replaced into rather stressful.

Q: As the title reads, Simply put: How did the original transformers series end? Aswell, how did some of the others, such as armada, energon, and cybertron end?: I don't know

Q: I have 2 flyback transformers one is from an old TV and the other one is from an monitor (new).I need to know the negative pin for the HV (high voltage)and the pins from the primary coil (input) and primary coil polarity. Can you tell me a method to find out these things? Thank you: reference 1: The flyback circuit diagram calls for two sets of coils: a primary coil and a feedback coil. The turn ratio is really not that critical so usually ANY two coils in the flyback primary will work. Locate two sets of coils on the horse-shoe-like configured pins by testing the flyback pins for continuity. Often times there are more than two pins connected to a single coil in the transformer. You will need to try the different positions to see which configuration works better for your application. After you have located two independent sets of coils on your flyback, hook them up to the circuit with any polarity. If you turn on the power any you don't hear a whine or hum, try reversing the polarity (switch the leads) of ONE of the coils. If nothing now, reverse the polarity of the other coil. If nothing now, reverse the polarity on the first one you switched again. So the take home message is trial and error. Flybacks can be very picky as to coil polarity because some of them have a rectifier built in them. So try each configuration (8 of them with two sets of coils) until it whines (Occasionally I'll find one that doesn't wine but VERY rarely). Any two sets of coils in a potted flyback should work, so don't try new coils until you're sure you've exhausted all possible combinations. The high voltage will come out of the fat wire from the top of the flyback-usually connected to the CRT with a suction cup. You will not be able to locate the high voltage return pin with a multimeter. The only way to do it is to bring the high voltage line down to the pins and whichever one it arcs like mad to is the one yer looking for. Try to stay away from arcing to any of the pins used for coils. High voltage is not so good for your transistor or power supply. second reference has a lot of useful info plus photos. . .

Q: I need help figuring out this transformer question. I have no idea how to go about it and any information or help will be useful.A 100-kVA, 60-Hz, 7200-480 V, single-phase transformer has the following parameters expressed in OHMS:Rhs3.06 Rls0.014Xhs6.05 Xls0.027Xm,hs17,809 Rfe,hs71400The transformer is supplying a load that draws rated current at 480V and 75 percent power-factor lagging. Sketch the appropriate equivalent circuit and determine:a) The equivalent resistance and equivalent reactance referred to the high side.b) The input impedance of the combined transformer and loadc) The load component of high-side current;d) The input voltage to the transformere) the exciting current and its componentsf) the input impedance at no load: A 100-kVA, 60-Hz, 7200-480 V, single-phase transformer has the following parameters expressed in OHMS: Rhs3.06 Rls0.014 Xhs6.05 Xls0.027 Xm,hs17,809 Rfe,hs71400 Primary winding is 15*N turns r 3.06 ohms in series with The primary leakage reactance which is L 16mhy(6.05 ohm @60Hz) in series with the magnetizing indctance Xm 17809 ohms 47.24hy which completes the primary series string the core loss is modelled as a 71.4k ohm resistor across the magnetizing inductance the secondary winding is 1*N turns R 0.014 ohms in series with the secondary leakage reactance is L 71.3UHy(0.027ohm@60Hz) the load draws 208.33A (100,000VA/480V) Z 2.304 ohms @ 48.6 deg 2.30448.6 1.786 ohms in series with +J 1.524 ohms(4.042mHy) (75% pf comes from voltage drop is seen from 2.304 ohms but only 75%(1.786 ohms) is resistive transfer from secondary to primary is done by multiplying impedances by 15^2 225 you should be able to do it from here.

Q: a lamp is connected to a secondary coil ( 80 turns) of a transformer by long leads which have a resistance of 2.5 ohms. Primary coil( 1600 turns voltage is 220v). the power input to the primary coil is 44w. 1) what is the voltage across the secondary coil2) what is the current across the secondary coil3) what is the electrical power dissipated in the lamp: Assuming perfect transformer. turns ratio 1600/80 20:1 secondary voltage is 220/20 11 volts primary current is 44/220 0.2 amps secondary current is 0.2 x 20 4 amps drop across wires is 4 x 2.5 10 volts. This assumes the 2.5 ohm number is for both leads, not each. voltage across lamp is 11v – 10v 1 volt power in lamp is 1 v x 4 a 4 watts. .
