Q: Production of high and low voltage switchgear transformer industry belongs to what industry category: Electrical, power distribution equipment? On the "switch talent network" or "electrical excellence network" to check it.

Q: 1.Why does transformer action can't take place in a dc circuit?2.on transformer coil what 5% tap means?: you okorder

Q: KW how to know how much transformer?: Transformer is rated by the kilovolt, is the apparent power, know the kilowatts, with the kilowatts divided by 0.8 is KVA, should stay a certain margin, preferably 20% of the amount. for your reference.

Q: How to use the experimental method to determine the transformer iron consumption and copper consumption: Is it in the motor experiment? The power measured by the no-load experiment is iron loss, and the power measured by the short-circuit experiment is copper consumption.

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?: G1 never really ended it was a cliff hanger that they wanted to expand into a series called Head Masters (only aired in japan) where Armada, Energon, and Cyberton (aka the Unicron trilogy) all played into each other Armada ending with the aurobots returning to cybertron, Energon the death of Unicron, and Cybertron the closing of the black hole Unicrons death created.

Q: Transformer rated capacity 500 / 750KVA (AN / AF) What does it mean?: Air cooling can improve so much no sure no problem, and now a lot of transformer air cooling and self cooling ratio is 100: 80, 100: 70, there are 100: 60.

Q: What is a transformer?: Impedance matching: the most common is the electronic circuit, the output and input connection, in order to signal unobstructed, usually using the transformer impedance matching, such as the old-fashioned broadcast, because it is using constant pressure output, speakers are high impedance horn , So it can only match with the output transformer. So, daily life can not be separated from the transformer, industrial production is also inseparable from the transformer.

Q: Hello, I'm new to electronics and I would like to know how is the current affected by a step-up or step down transformer. EX: Lets say you have a pure AC wave (60Hz , 25vac, 5A) hooked up to a 1:4 power transformer with a current rating of 10A, What will the voltage and current be and why? Thank you!: Given: Primary Voltage (Vp) 25 Volts Primary current (Ip) 5 Amps Turns ratio 1 :4 Calculated: Secondary Voltage (Vs) (Vp)*(turns ratio) (25V)*(4) 100 Volts Secondary current (Is) (Ip)/(turns ratio) (5A)/(4) 1.25 Amps Why? Because the turns ratio steps up the Voltage by a factor of 4. The resistance connected to the secondary is reflected back into the primary at a value such that (Vp)*(Ip) (Vs)*(Is). (25V)*(5A) (100V)*(1.25A). In this example the load resistance was 100V/1.25A 80 Ohms. But this 80 Ohms is reflected back in to the primary as 25V/5 5 Ohms. If no losses a transformer's resistance ratio always equals the turns ratio squared. Thus in this example; (80 Ohms)/(5 Ohms) (4^2). The primary current is always determined by the secondary current which is determined by the load impedance. But in this example the primary current (5A) was given and it was necessary to use the turns ratio to calculate the necessary secondary current that determined the 5A primary current. Additional comment: Hang in there Dr Jim. I was unable to follow your explanations in this particular problem but I am sure that every thing is going to be all right in the long haul of things. After all there are other things in life besides transformers.

Q: Transformer tap adjustment there are several ways? What are the advantages and disadvantages?: 1, no excitation adjustment or no taps. 2, with taps. Their advantages and disadvantages are as follows: 1, no taps: taps when the transformer must be shut down after the power, the advantages of safe and reliable, but the disadvantage is to adjust inconvenient, and often because the tap position can not meet the needs of less. 2, with taps Advantages: easy to adjust, do not have to turn off the transformer power can be adjusted, and the general tap position more easily meet the requirements. Disadvantages: due to load adjustment prone to problems, high cost, compared with the same capacity transformer volume, taps device maintenance needs a long time to blackout.

Q: I have two-way transformer (120Vlt;240V) that has a surge capacity of 2000W and a continuous capacity of 1600W. The transformer is plugged into my wall socket and is, on its output side, attached to a power surge protector that leads to six separate sockets. There are periods where not all six sockets are in use - in this specific case, the only appliance is a 50W fan - and my question is, does the transformer still eat 1600W off my meter and waste most of it as heat, or is it nice and intakes maybe only 60W and inefficiently converts it to the required 50W? If the company/model comes into question, I can only say the transformer is of Taiwan origin - the company logo is a 'Z' with small D intersecting the two parallel lines of the former letter, all against a blue background - and has a model number of TC-2000. Many thanks.: If you plug in a 50W fan into your 1600W transformer, it will only draw what it needs + a little more for losses. You are right about the losses that you feel/see with this transformer. Some of the voltage conversion is lost as heat as a transformer is not 100% efficient. (As a matter of fact, no energy conversion system is 100% efficient as stated in the 2nd law of thermodynamics). A transformer typically is pretty efficient; usually above 95%. So you would be drawing maybe an extra 1 or 2 watts, not 10, with your fan. When nothing is plugged into it, it should draw some minuscule power due to losses, but not very much and definitely not 1600W. I personally would not let it be plugged in all the time. If it of a cheap or poor design and not UL (Underwriters Laboratory) or other agency rated, it could short out and cause a fire. But that is just my anal-retentive nature
