ZGSB Type Pad-mounted Seal Structure Tranformer

Q: Hello everyoneI have a 110V hardware plugged in at home (we use 220V) by way of a step down transformer and I was wondering if transformers 'use' more power than usual. I don't want a nasty electircal bill.Because even when the hardware is 'off', the transformer itself is still on. It still hums. I am wondering if the transformer is constantly pulling power out of the wall socket 24/7 if I leave it on.Any help will be greatly appreciated. Thanks all.: No okorder

Q: How to test E-I Transformer having 10 terminals (pins) 5 on each side ? thanks: If a transformer has shorted turns, every winding will show drastically reduced inductance than is required for the circuit to operate. For example, the inductance of an audio transformer has to be at least L Z/(2piF), where F is the lowest frequency, audio ~20Hz and Z is the circuit impedance. So an 8 Ohm speaker winding should have 60mH or more inductance. The resistance of the winding should be less than 10% of the operating impedance. The maximum operating frequency of a transformer is something less than the self resonance and the minimum load is that which provides critical damping of the self resonance. So large transformers just work better since they have more inductance and less resistance With a signal generator, scope and some series resistors, you can find the inductance etc.

Q: Rules for the operation of cooling devices for oil - cooled transformers: E, strong oil cycle air-cooled and strong oil circulating water-cooled transformers, when the cooling system failure to remove all the cooler, allowing the rated load to run for 20 minutes, such as 20 minutes after the top of the oil temperature has not reached 75 ℃, then allowed to rise to 75 ℃ , But in this state the maximum time to run no more than 1 hour. ?F, under normal circumstances, the transformer no-load operation, the cooling device two groups of work, a group of auxiliary, a group of spare, the remaining disabled; transformer low temperature, light load, the four groups of work: a group of auxiliary, a group of spare, the rest Deactivated; transformer high temperature, full load, a group of auxiliary, a group of spare, the rest all into work.

Q: For example, if you have a battery that puts out 1 amp, can you use a step down transformer to turn that into 1000 Amps. Or is there some sort of limit to how much one can increase current in a circuit?: Battery power is DC that cannot be used on transformer. Transformer has its limitation the total input power is near equal to total output power. Example: Input power is 100V ac 1A ,that equal to 100W by step it down into 1V , it can provide 100A,because it is still 100W Or by step it down into 0.1V, it can provide 1000A, because it is also equal to 100W. BUT 100V 1A CANNOT BE CHANGED INTO 100V 100A WITH TRANSFORMER.

Q: I have a nice little 120VAC to 7.5KV transformer that used to call an air purifier its home, but I'm not sure how to wire it. I have some guesses, but I want to make sure I don't burn down my house so I am hoping to verify them with the help of the yahoo answers community.: Transformers consist of a primary and secondary winding. If you are certain of the AC input side (and the fact that they are black and white suggest you are) then the green and red wires are the secondary and would produce the 7.5kv AC output. Neither of these wires can be connected to ground as that would short the transformer and more than likely fry it,trip a circuit breaker , cause a fire or all three. Secondary windings with more than two connecting wires would indicate a transformer that can be tapped, which means that various voltages can be obtained depending on the combination of the output wires. 7.5 KV is a very dangerous output and if you are using the transformer outside of it's intended device, a fuse on one of the AC leads would be an absolute necessity.

Q: A transformer consists of 250 primary windings and 838 secondary windings. If the potential difference across the primary coil is 25.5V , what is the voltage across the secondary coil ? If the potential difference across the primary coil is 25.5V , what is the effective load resistance of the secondary coil if it is connected across a 135Ω resistor?: Transformer equation, N_pV_pN_sV_s V_s (N_p V_p)/N_s, plug in the numbers and calculate. N_p/N_s sqrt(Z_p/Zs)

Q: I am in a verge of purchasing a house that is located very adjacent to a polyphase transformer. I hear of the stories that say about the adverse effects that are caused by these transformers to various electronic goods that are there in the house. Please clarify.: Poly-phase transformers which are merely 3-phase transformers don't really cause anymore interference than any other transformer. If the thing was up against your wall, then maybe it would mess with radio or cell phone communications, but really your main interference concerns would be if you were near high voltage transmission lines. Why not ask the previous owners or neighbors in the area if this transformer has interfered with their electronics.I doubt it.

Q: Is the secondary current rating of the transformer line current or phase current?: For star-wiring products, the line current = phase current For triangular wiring products, the rated current refers to the line current (phase to phase current)

Q: if the transformer in a wall charger steps down the voltage from my wall to 120V does this mean i could use it in the reverse direction as a step up transformer? I want to combine 4 car batteries making 48V and plenty of amperage, but what can i use to get it up to 120V for my 1/2 hp motor?: Truthfully you'd be better off setting up the batteries in series (for higher amperage) and buying a decent 12V power converter. Your two biggest problems will be if the batteries can handle the start up power surge generated by that motor and the power loss from converting the dc to ac in the converter.

Q: actually I've many questions :) I've opened many mobile chargers and I didn't found the usual (bulky) transformer . I found only a small transformer and I think it called smps transformer.1- I can't understand how bulky transformers can be replaced by small ones! what is the idea ?2- are smps transformers connected directly to 220 volt like the bulky transformers ? if no, what is the design of the circuit that makes small transformers are able to be connected to 220 volt ?3- do smps transformers make a voltage drop like the bulky transformers ? or they have another job ?4- some smps transformers have 4 pins and the other have 5 or 6 pins, I know it should have 2 pins for input and 2 pins for output, why some of therm have more than 4 pins ?Thanks in advance, I hope i'm not bothering you because of my many questions :): The higher the switching frequency, the smaller you can make the transformer without the metal core saturating.
