- Q: Single bus sub-section for power distribution, transformer with a prepared and dual-use how to understand
- One with a prepared, you can only put one of the transformer, any of its transformers can all the load to bring all the general into the line breaker and bus in the breakdown of the circuit breaker, interlock between the three, A change vote, B variable can not vote, or vice versa, B cast A can not vote. This is the nature of the load mostly for a load, power supply is necessary for high reliability, but also the largest investment. Dual use can be divided into several, mainly refers to the change can be put into use, and some can be put into the parallel use, in some cases is not allowed to use in parallel, is the three circuit breakers with interlocking Three locks two spoons, three circuit breakers can only vote two. At the same time the capacity of the transformer is also different, some are prepared, some are dark spare, the specific use depends on how the original system design. hope this helps.
- Q: if the transformer converts 240v ac to 8V ac, ratio 30:1 then it should step up the voltage by the same ratio, i.e, 15V ac to 450v ac.but it's not the case !!
- It must be using different terminals for step up and step down.
- Q: 315KVA transformer high-voltage side need to use the specifications of the high-voltage cable
- You are not very specific, according to the general distribution transformer, then the high side of 10kV, low voltage side of the 400V; high voltage side of the actual current is small, the voltage is high, so the main choice of cable attention to insulation, pressure and other properties, specifications suggest that you choose YJV-1 * 25 (10KV) cable, 25 mm square cable. (High-voltage cable diameter is not too small)
- Q: I know that both at some point were comics made by Marvel and that Thundercats was animated by a japanese studio and Transformers had an original series in japan but was here in america first. That's the info I have but what is what? And please no guessing if you don't know please don't play favorites between american and japanese cartoons, ok?
- Transformers was an American production but it had some helps from a Japanese studio. It is like this until Headmaster which is a 100% Japanese production. The last US Transformers US made are Rebirth which came out in fact after Headmaster.
- Q: Hi, I'm trying to build a Jacob's ladder or maybe a Tesla coil. What should I use to get enough voltage? A lot of resistors or a transformer? (Are they also safe for humans?)
- I don't think there is any way to use resistors to increase voltage. Neon sign transformers are the usual choice, but they are not safe for humans. Death is not rare and they likely cause illegal radio interference. Voltage multipliers are likely safer, but the Jacob's ladder arc will be dimmer and shorter. Neil
- Q: does anyone have the trailer for transformers
- No there is no trailer yet because there is no footage yet. The film is currently 'in production' and will hit cinemas next year. Look for a teaser soon enough.
- Q: I found out that rising the frequency of the power going to the primary will rise the output/ secondary voltage. So, if I feed a 60 hz 1:1 turn ratio transformer 100volts at 60 Hz (pure sine wave), the output will be 100 volts. but if I increase the frequency to 400 hz and keep the primary voltage at 100V, (pure sine wave) the output/secondary voltage will go above 100 volts. Or no?
- While transformers can be very efficient, they are not perfect, so for any significant load the voltage does not exactly follow the turns ratio. The losses will be different at varying frequencies, how they will differ is hard to predict without more information on the transformer. I'd imagine hysteresis losses might be noticeable, but that would probably cause core heating more than affect voltage much. Generally I'd expect little change in voltage especially at no load.
- Q: What is the transformer capacity ratio? Capacity than 100%.
- Transformer capacity is the power of the transformer, the capacity ratio is the power ratio, such as 1000KA transformer and 200KVA transformer is not suitable for parallel use. Capacity ratio = 5: 1 greater than 3: 1 Capacity than 100% -------- is the meaning of 1: 1 (such as 500KVA and 500KVA, 200KVA and 200KVA and so on. Transformer side by side conditions: ① to participate in parallel operation of the transformer must be the same wiring group. ② the primary voltage of each transformer should be equal, the secondary voltage are equal. Otherwise the secondary side of the circulation caused by overload, heat, affecting the load, and increase the power loss, reduce efficiency; ③ the transformer impedance voltage (short circuit voltage) percentage should be equal, or with load after the load distribution unreasonable. Because the large capacity of the transformer short circuit voltage percentage, small capacity of the transformer short circuit voltage percentage is small, and the load distribution and short circuit voltage percentage is inversely proportional to this will cause large transformer distribution load is small, the equipment is not fully utilized; and small transformer distribution of the load Large, easy to overload, limiting the parallel operation of the transformer with load operation.
- Q: Three-phase transformer how to calculate the current, ah, the formula is?
- For example: 10KV / 0.4KV, 500KVA transformer Primary current: I1 = 500 / (1.732 * 10) = 28.9A Secondary current: I2 = 500 / (1.732 * 0.4 = 721.7A
- Q: do you think transformers is cool or not and why?
- In the hands of a better director, Transformers could have been great. Unfortunately, Michael Bay just made it a loud special effects extravaganza and I lost interest about half way through. Bay's movie still might have been better if it had been 30-45 minutes shorter.
