Q:The specification states that the 35KV substation is capable of obtaining the power supply after the main transformer is powered down. Therefore, in this case, the transformer used should be connected to the power supply side of the circuit breaker. My question is that the main transformer which, the main transformer is not connected to the power supply side of the circuit breaker?: 1, the so-called main transformer or (plant) with transformers are transformers, but according to their use of different names. The so-called main transformer: generally in the power plant or substation are so called, its function is for the system through the required level of power transformer; the so-called (factory) with the transformer is inside (power plant interior) Electrical equipment to provide power transformer. 2, the (plant) with the transformer power supply connected to the main transformer on the same bus, and some received another external power supply, so that when the main transformer can be maintained when the maintenance (plant) to continue to have power!

Q:Hi - I have some questions for any electrically minded people out there!I have a low-voltage 12v transformer, as pictured here:: What you have, in actual fact, is NOT a transformer but an electronic power supply that has been called a transformer by convention. In this situation, neutral /or live may exist. If supplying incandescent lighting (which I suspect you are), having these reversed is not a problem. Such transformers stop working for a few reasons: 1] they are too small for the load. 2] dimmers are used whereby they shouldn't be used with the type of transformer you have. 3] they are overheating due to being surrounded in thermal insulation (fibreglass etc). 4] they are of a cheap design. 5] the power supplied to them is unacceptable (voltage, waveform etc). To safely disconnect a lamp that is connected to the output of this transformer, the circuit breaker supplying the device must be switched off. If you do not wish to immediately connect anything to these bare wires, they must be insulated from any other contact. This can be achieved with the use of wire nuts (American devices), which are not permissible in Australia I dare say, also the UK (for very good reasons). The alternative to a wire nut is an insulated connector that has screws to facilitate a good connection. Once this connector has been applied correctly, it must be taped with PVC tape. Generally, this can only be done correctly by an electrician. If you are in the UK, you will have similar rules to that of Australia, whereby only qualified people can deal with such things.

Q:Transformer turns around the number and how much V is calculated: 3, seeking wire diameter What is the current required to output 8 volts? Here I assume 2 am. Transformer output capacity = 8 ╳ 2 = 16 volt Transformer input capacity = transformer output capacity / 0.8 = 20 VA Primary coil current I1 = 20/220 = 0.09A Wire diameter d = 0.8√I Primary coil wire diameter d1 = 0.8√I1 = 0.8√0.09 = 0.24 mm Secondary coil wire diameter d2 = 0.8√I2 = 0.8√2 = 1.13 mm The voltage after the bridge rectifier capacitor is 1.4 times the secondary voltage of the original transformer. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.).

Q:Is the transformer output DC or AC?: Is the exchange, after the diode rectifier into a DC.

Q:1. a district 800 + a layer of 500mm2 shopping malls should choose how much capacity? 2. A 315kva transformer has been for a district 600 households electricity, ask there is a 70 households can access the transformer?: In the actual choice, should adhere to the "small capacity, dense point" principle Distribution transformer location should be located in the load center, and the power supply radius of not more than 0.5 km. Distribution transformer load rate between 0.5 to 0.6 the highest efficiency, At this time the capacity of the transformer is called the economic capacity. But if the load is relatively stable, then the continuous production of the situation can be selected according to economic capacity transformer capacity.

Q:does anywon kno if michael bay will bring back any robots that died from his previous movies? like jazz or bonecrusher or brawl anything like that. and i know that their making transformers 3 but does anyone know whats its going to be called or what are some new transformers? thank u for all ur answers. exept the crappy wons. il just delet thos. even tho u cant. ???: Okay let me start off by saying i'm not a nerd i just love transformers. lol. But from what I've heard the title is Transformers: Ascendents of Cybertron. The main villian is Shockwave. Megatron, Starscream and Soundwave are the only three that have been confirmed to be in the third one as of now. For the autobots Optimus, Bumblebee, Ironhide, Ratchet, Sideswipe, and the twins who Bay said weren't coming back are coming back. New characters for autobots include a robot named Silverbolt a red ferrari, a purple car, a blue car, and an autobot scientist. Also there introducing a new team of robots that will work with the autobots called the Wreckers, three nascars. There will also be two robot assasins ( decepticons ). And as for any returning unknown but i can tell you this they have comics that take place in between the movies and there coming out with a comic series called Transformers: Nefari or something like that which takes place after the second film and somehow Ravage the dog like decepticon who was killed by Bumblebee somehow comes back to life and Alice that robot chick from college somehow comes back and was captured by sideswipe after stealing an RV and was taking to NEST for tests. Oh and one more thing. The film is supposed to start of during the days where John F. Kennedy was president and something with a decepticon on the moon happens. But the film supposely says that the decepticons had something to do with the cold war and World War II. Hoped this helps

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:i went to see transformers on july 3rd. they had about 5 or 6 previews before the actual movie started. the very last preview showed and party to someone called bob. he was leaving, going to japan. then the lights went out and a big groan was let out and a earthquake happened. they all went out to the roof, and in the distance, a big orange ball was exploding, shooting out fireballs and lava. they only said it was coming out on january 18 2008, and they didn't give the name.please help, i need the name of this movie: Yeah I have the same question. I went to see Transformers and I was like what the hell? That is a movie made by the no-name brand. I do not think it is I Am Legend, thought that looks like a good movie. That name of the movie was sort of obvious. ^^

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.
