- Q:Does anyone have any knowledge or experience with what happens if you try to run two different power supply transformers from the same AC line input. Can you do that? I have one transformer with a primary DC resistance of 28 ohms. I have a second transformer with a primary DC resistance of 265 ohms. I want to run these two transformers from the same AC power cord input. I tried connecting their primaries in series across the AC cord input, and the resulting secondary outputs from both transformers were lower than expected for a no-load condition. I am a little concerned about trying to connect the two transformer primaries in parallel.Any ideas?
- Transformers don't work with DC inputs. Transformer physics require an input that changes with respect to time. That's why they work with AC. When you apply a DC input to a transformer, it looks basically like a low resistance, depending on the size and mass of the wiring. In order to provide DC as an input to this thing you have, you need a circuit to chop the DC and turn it into AC before it is input to the transformer.
- Q:A transformer is used to step down a voltage of 11KV to 220V. Given that the transformer has 3200 turns in the primary, calculate the number of turns in the secondary coil.Another transformer is used to further to step down 220V to 110V. its input current is 3A and the output current is 5.6A. Calculate its efficiency
- Q1. Let the number of primary turns Np; number of secondary turns Ns. Let the primary voltage Vp; secondary voltage Vs. Then fundamental transformer theory gives us: Vp/Vs Np/Ns. So: Ns (Vs/Vp).Np i.e.: Ns (220 / 11,000).3200 64. The turns ratio is 50:1 Q2. The product of volts and amps is called the V-A of the transformer: volts x amps. An ideal transformer would generate zero losses in transferring electrical energy from primary winding to the secondary winding. But there is no such thing as an ideal transformer: the transference of energy means that some energy gets lost: in heat, eddy currents and hysteresis losses. For this Q, the input VA 220 x 3 660 V-A, and the output V-A 110 x 5.6 616 V-A. The V-A efficiency (V-A out) ÷ (V-A in) 616 / 660 0.933 93.3 % N.B. This is not the same as the watts efficiency, power in ÷ power out: the V-A efficiency does not take power factor into consideration.
- Q:If load loss of a transformer at full load is 100kW, the load loss at 50% load will be a) 50kW b) 75kW c) 25kW d) 100kW. i think its 25kW because load loss is inversely proportional to the square of loading percent. kindly explain . is it right.
- I'm guessing load loss is the same as copper loss, which is due to the resistance of the wire in the transformer. This loss is (I^2)(R wire) so the answer is c) 25 KW The current is 50% at 50% load, I^2 0.25
- Q:Does the production transformer require 3C certification? Does the country have any specific requirements?
- The so-called 3C certification "China Compulsory Certification" Is China's mandatory product certification referred to. If your company's products can be sold publicly, without the need for 3C certification, it does not require mandatory certification.

- 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.
- (4) Splitting coefficient: The ratio of split impedance to crossing impedance. The description of the method of the standard method shows that the commutation reactance measurement of the rectifier transformer is similar to that of the transformer short-circuit impedance measurement. The difference is that the measurement of the short-circuit impedance is usually made by connecting the low-voltage side of the transformer and the high-voltage side to the rated current, And the commutation reactance measurement of the rectifier transformer is to short-circuit the high-voltage side and to measure the voltage between the terminals at the low-voltage side with the rated single-phase current. It can be seen that the commutation reactance of the split transformer is a half-crossing impedance.
- Q:I have an old xray machine with a large step down transformer.Its not shorted but the paper insulation looks to dry. Is there a special oil for this? Thanks.
- The manufacture of the transformer would have provided environmental protection. There are many ways to provide protection but most involve large pressure cookers that are designed to apply high pressure to the transformer will drying. Various waxes and epoxies are used and the pressure makes certain the sealer is driven into the transformers windings, then allowed to set. As far as I know, except for certain types of large transformers where the entire transformer is installed in a bath, oil is not used.
- Q:I need to find a transformer that will convert 480 input to 240 output for a motor controller. Where can I get this type of transformer? I've only been able to find 120/240 transformers.Thanks.

- Q:I love the movie transformers and cant wait till part 2.Anyone know anything about it specifically???
- I finally saw it a month ago on dvd and I hated it. It was another typical Michael Bay film, full of action, special effects, little characterization, and not that much story. Even some of the scenes and dialogue were horrible. Having Optimus Prime say my bad was corny and embarrassing at the same time. Prime would have never said that in the 80's cartoon series. Or when one of the Autobots decides to pee. Dumb, just plain dumb. I'd give it 2 out of 4 stars.
- Q:How to use the experimental method to determine the transformer iron consumption and copper consumption
- No-load test for iron loss; short-circuit test copper loss. I suggest you read the book, see the information.
