Flyback transformer usage?
- A 'flyback' transformer won't do anything but blow the breaker if you plug it into the wall. They're designed to run at 15,750 Hz. and yes, they do couple a 'sawtooth' waveform out to the horizontal deflection coils of the 'yoke' around the base of the CRT which deflect the electron beam to produce an image. If you want some -great- sparks, go out on the 'net and look ou plans for a 'Tesla Coil'. I've built a couple of those that would draw an arc several inches long. And since they're very low-current (on the secondary side) they're quite safe to play with. HTH, Dougs
Transformer Current Calculations?
- Given its capacity this is almost bound to be a three phase transformer. You need to know the connection of the primary and secondary windings (Y or Δ) to determine the windings' currents. You can basically calculate the rated currents from the kVA rating and voltage without using the impedances, eg. Ip primary rated current 630/(11 x 3 x √3) which assumes a 3 phase transformer with a Y-connected primary. Edit: If the capacity value is totally unreliable then there's no way you can find the rated current with only the other values you give. You need the load impedance as well.! This applies whether it's a single or a three phase unit I'm afraid. Why do you bother me with useless data? If you do this kind of thing to your employer in later life you'll rightfully get scalded!! On top of that you don't even initially say please or later apologise for such a gaffe.s

AC Transformer Question?
- A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil. Power output Power input Power Volts * Amps 350 13,000 * amps Amps 0.0269 amps current in the primary coil? House voltage 120 volts 350 120 * amps Amps ≈ 2.92 current in the secondary coil? Amp Ratio 2.92 ÷ 0.0292 100 : 1 Wire ratio 100 : 1 A How many turns of wire does the secondary coil have? 50,000s

transformer tap changer operation?
- A transformer raises or lowers voltage based on the ratio of the number of coils of wire between the high and low voltage sides. The tap changer adjusts the voltage by changing the point of contact on one of the coils. Bypassing or including coils of wire changes the turns ratio of the transformer which by default will change the output voltage in direct proportion. Assuming you're referring to a tap changer under load Each step will either raise or lower the voltage by 5/8% or 3/4 volt on a 120 volt base. A reactor coil (yet a third smaller coil) is used during each step to temporarily carry the load so the contacts won't be damaged by arcing while switching. In other words, the lights won't blink during a tap change. A control panel constantly monitors the output voltage and automatically raises or lowers the voltage in an attempt to keep the output within its programmed bandwidth. Depending on the design, the tap changer may or may not be on the high voltage side.s

220 volts to 24 volts transformer 20a is how many watts
- Transformer consists of iron core (or core) and coil, the coil has two or more than the winding, which connected to the power supply winding called the primary coil, the rest of the winding called secondary coil. It can transform AC voltage, current and impedance. The simplest core transformer consists of a core made of soft magnetic material and a coil of two turns on the core, as shown in the figure.
Turn left to turn right
The role of the core is to strengthen the magnetic coupling between the two coils. In order to reduce the iron in the eddy current and hysteresis loss, the core from the painted silicon steel sheet laminated; between the two coils there is no electrical connection, the coil by the insulated copper wire (or aluminum) A coil connected to the AC power supply is called the primary coil (or the original coil), and the other coil is called the secondary coil (or secondary coil). The actual transformer is very complicated, inevitably there is copper loss (coil resistance heating), iron loss (core fever) and magnetic flux leakage (by air closed magnetic induction line), etc., in order to simplify the discussion here only describes the ideal transformer. The ideal transformer is set up under the condition that the leakage flux is ignored and the resistance of the original and secondary coils is ignored. The loss of the core is ignored and the no-load current is ignored (the current in the secondary coil turns the original coil). For example, when the power transformer is running at full load (the secondary coil output rated power) is close to the ideal transformer situation.s
