FAQ

I have been reading wikipedia and have gotten confused.Va.Number of Coils on side a---- ._________________Vb.Number of Coils on side bwikipedia mentioned how power companys use transformers for converting to high voltage power li nes then use transformers to bring the voltage back down.Focusing on the transformer that jacks the voltage upwirea-[side a-Transformerxyz- side b]-wirebso assum wireb is the high voltage power line.--Which side of transformerxyz would have more coils ? My guess is that side b has more coils then side a--Is it safe to say that the wattage of side a is equal to side b?--they said something about magnetic flux, does this just mean that the material connecting side a to side b has to be magnetic?--they said that the insulation wears down in transformers over time due to heat. what is causing this heat?--they said something about leakage and spacing of coils, what does this mean?tyVVVVVVVm

The number of turns is proportional to the voltage on that side. So if you connect a voltage to the side with 100 turns, and the other side has 1000 turns, you will get out 10 times the voltage you put in. However, the current available is only 1/10 as much, so the output power is the same as the input power (wattsvolts*amps). To transfer power efficiently, especially at low frequencies, both coils of the transformer are wound around the same piece of magnetic material. All wire has some electrical resistance. When current flows through it, voltage is produced (voltsamps*ohms), and the combination of voltage and current produces heat. The wires making up the coils are covered with insulation, and there is insulation between the coil and the core, and between the two windings, but the voltages may be 100,000 volts or more, and this is enough to cause sparks between windings or from the windings to the frame if there is a spot with no insulation.

I was planing on buying transformers but my friend told me about skyrim and it looks pretty good, which one is better and funner?

SKYRRRRRIMMMMMMMMMM!!!!!!!!!!!!!!!!!!!!! ZOMG

I have been reading about pulse transformers and i am curious if there exists a pulse transformer that would take 1 pulse/second or even less and convert to very low voltage high current. If not, would it be possible to make one? Any info is very appreciated! Thx!

Pulse transformers can be wound to any turns ratio that is desired. That being said pulse transformers have small cores and therefore handle small amounts of power. You can find cores on those old mother boards that are no longer in service and junk computer power supplies also have a couple of cores. These toroids were normally used as filter inductors to remove spikes from DC or low frequency lines. You can easily rewind them for pulse transformers.

What is the meaning of auxiliary transformer, sub-variable and box change What is the difference (in addition to the capacity difference), how to work with, thank you

During the main transformer failure or overhaul, the auxiliary transformer provides the substation's own electricity. Maintenance of substation lighting, high and low voltage switch action, with the cabinet switch operation, for instrumentation and automatic control system work, sub-change can be box change,

Calling all fans of Transformers! I am looking for anyone to tell me if Transformers Animated is coming back for a third season on Cartoon Network. The reason why I am asking this question is because I recently bought the second season of the show and noticed that they have a lot of information on new characters as a special feature and I am wondering if those characters will be in the third season of the show.

That would suck sooooo bad if it is cancelled. All that build up in the first season with super villains and no Megatron and like, 3 Decepticons till the end of season 2 for what! To take it all away just as its getting good and finally setting up a full on Autobot Decepticon war There better be a season 4 or this series will go in the forgotten bin with Robots in Disguise as another series that took forever to set just for 1 big battle then that's the end. But if it is the end then that will teach the writers for holding out on what fans really want. I can not sit through season 1 or 2 again, except the season 2 finale.

Transformer Lightning

Dry coil internal coil will burst open, so that the transformer outside the four sides of the shell will be bulging. Cylinders on the porcelain will burn black, porcelain will be black and cracked. The line breaker is tripped.

Here we go I have 4 transformers (230V to 12V) and 4 radio receivers. I have one transformer connected to one receiver. Similarly all transformers are connected in the same way. Now, I used a connection box (normal heavy duty ones bought at hardware shop-i think its made of some kinda fibre) to house 2 transformers and 2 receivers. This scenario is happening in my roof. I went to open one of the box the other and the transformer was hot. It wasn't hot to the point of not being able to hold it. But hot enough for me to hold it for for a while before letting go. So the basics here is that one transformer is only powering one receiver which is OK for the load. But I am a bit worried as to whether this can start a fire in the roof. Any advice please? Can this scenario lead to a fire? (Even though there is no overloading)

Pete's answer is a winner. The only thing I'd add to it is that all electronics that generate heat must be vented. You didn't say you had any venting. Sometimes that venting can be convective current venting (hot air rises, cool air enters from below) OR can be a cooling fan. Like Pete said, without specs and loads we can't tell for sure if there's a danger. And until you KNOW there is no danger, assume there is. Hope this helped. '')

1. If the input voltage is 100V and output voltage is 200V, which side of the transformer winding will be primary?(a) 100V side (c) winding with loss turns(b) 200V side (d) winding with more turns2. Which of the following statement about humming of transformer is true?(a) The frequency of humming tone is 100Hz(b) The frequency of humming tone is 50 Hz(c) The humming is caused by a vibration of the low voltage winding through which the high current flows(d) The humming is caused by the private force of attraction between the lamination of the core3. In a 10 KVA, 230/1000V 1-? transformer, the no load current will be around(a) 3 A(c) 10 A(b) 0.5 A (d) 0.9 A

Each turn produces about the same voltage, and the primary is the input side. 1. The input voltage is lower than the output voltage, so the input winding (primary) must have the lower number of turns. 2. If the line frequency is 50 Hz, then a and d, since the vibration force is proportional to the magnitude of the current, but not the direction, so both half cycles produce the same force and there are two cycles of force each voltage cycle. The main vibration forces involve the magnetic attraction between the laminations and their magneto-striction (change in dimension as magnetic flux magnitude varies) 3. The load full load primary current will be roughly the power divided by the voltage or 10,000/23043 A. The no load current will be a few percent of that current, but I do not know the typical fraction for a transformer of that size. My seat-of-the-pants guess is a, about 7%. -- Regards, John Popelish
