Q:Transformer input power how to ask?
Transformer calculates power factor If the capacity of the power transformer is denoted by S, the output active power is expressed by P, then the power factor cosa = P / S.
Q:Do electrical transformers protect the surrounding wires from power surges?
No, the transformer itself wouldn't ground it. I don't know if they have some kind of surge protector, by the transformer would just 'pass it on' (most likely blow a fuse if the trannie survived
Q:What is the rated current of the 80KVA transformer?
Rated current formula: I = P / 1.732 × U = 80000 / 1.732 × 380 ≈ 122 (A) (Current contains active and reactive current)

Q:what the difference between ballast and transformer?
Ballast Transformer
Q:Did Transformers Animated ended with Season 3? Or is there going to be Season 4?
Transformers animated ended last Saturday with Endgame part II. It was ended because of the movie coming out and Hasbro wanted to focus on movie merchandise. There's been some talk of maybe it starting up again after the movie or even a new cartoon.
Q:Should I get Transformers: Fall of Cybertron or Just Cause 2?
Just cause 2, but only because you chose 2 horrible games to buy. Just cause is basically just flying around doing crazy ****, other than that the game gets way too repetitive. As for Transformer, yeah I don't even need to emphasize on that game.
Q:Would this idea for a transformer work?
1. I don't see why a power transformer from a UPS would get hot unless it was overloaded or short- circuited, or incorrectly connected. 2. If you are going to power the circuit you indicate, and it requires 12V at 5 A., there are plenty of power transformers off- the shelf you could use to build a power supply with. It would need to be rectified and filtered, for DC output as you require. Possibly voltage- regulated as well? Gets costly Another way would be watch OKorder or similar for a switchmode power supply that does the job (more efficient, less weight). Example: I used 2 computer power supplies I bought brand new, for $A5.00 each, to power a linear RF amplifier that needed 10V DC @ 15A., and a bias supply of -5V @ a few mA. I wired them together to produce 10V DC 26A, using the 5V 26A outputs in series. I only needed to isolate the neg. end of 1 of the 5V outputs from the common ground to get both in series. The bias -5V I derived from the -12V out of one of the supplies, with a 7905 voltage regulator to cut it to -5V. My point is, this entire power supply weighs about 3/4 KG. It is voltage regulated and overload protected, and compact. A standard power supply with output levels like this would be considerably heavier and bulkier, and considerably more expensive.
Q:what is the work of a transformer?
A transformer is used to increase or decrease voltage, but only for alternating current. It won't work with direct current. When a current alternates in a current carrying conductor a magnetic field expands and collapses, changes polarity and expands and collapses again. It then repeats the process for each cycle of the alternating current. If you have another current carrying conductor within this changing magnetic field, then another current is induced into that conductor as a result of the magnetic field cutting the conductor. This is called induction. So an alternating current in one conductor can induce a current in an adjacent conductor. In a transformer we have two coils, the primary and the secondary. If we have twice as many turns in the secondary to the primary we have a step up transformer - it steps up according to the ratio of turns between the two coils. Here the ratio oi 2:1 so the voltage is increased by 2.
Q:Is the power usage of a Transformer always equal to its capacity?
The power TRANSFORMED by a transformer is governed by the load connected to the transformer. So if you apply a 50W load, then the output of the transformer will be about 50W. No electrical component is perfect - all incur some kind of losses. In the case of transformers, there are two kinds of losses. Through losses (aka 'copper losses') are losses that occur as (and because) power is passing through the transformer and occur as a consequence of heating in the conductors that make up the windings of the transformer. The magnitude of copper losses depends on the design of the transformer, but on a small transformer might be something in the range of 1-5% of the power being transformed. So for your 50W, load, the copper losses might be as much as 2.5W. The other form of loss with a transformer is excitation loss. These are losses associated with magnetization of the iron core of the transformer. These losses are fixed and irrespective of the amount of power being transformed. On a small transformer, core losses could be as much as 1% of the transformer RATING. In your case, the rating is 1600w (that 2000W 'surge' rating is simply a short-time thermal overload capability - its not really a rating). So 1% of 1600 watts is 16 watts. So what that means is if the output of the transformer delivered to the load is 50 W, then the input to the transformer including losses might be 68.5W.
