Q:I watch Terminator Salvation first, it was really good I thought. The best part of the movie, I thought, was when T-800 turns evil again and attacks John. It took both John and Kyle to beat T-800.But other than that, I didn't really enjoy Transformers 2. Neither did I make plans to watch it, and I thought they should've dropped Megatron as one of the villains again. I thought it was average.But which is the better sci-fi movie of the year? (I think Star Trek is, but that's out of the question.): I thought Transformers was the better movie. There's a lot of history and storyline involved, but even if you don't know all of it, the movie is still very good.

Q:Hi, thanks for reading my question. I'm an electrician with some basic knowledge of electricity but this is puzzling me. In the USA, a single transformer on a pole means split phase. Three transformers on a pole means 3 phase. What does two transformers mean? Is it split phase with a high leg?Thanks: In my area there are sometimes 3 or four transformers on a pole. This is a residential area though and a lot of the houses use electrical resistance heating. Looking at the transformers on the nearest pole I see see two wires output and a ground cable coming from each transformer. The transformer coming to my home is single phase 240 volt ( 120V on each hot line). The transformers are rated at 50 kva, so I'm assuming four 50 kva transformers was probably cheaper and more flexible than using one 200 kva transformer.

Q:A step up transformer increases 17.7v to 120v. what is the ratio of the current in the secondary compared to primary? Assume 92% efficiency.HELP PLEASE: Preliminary necessary comments. (i) This question - and consequently my answer - assumes that we have a perfect transformer: such a transformer will have an efficiency of 100 %. (If this was not a perfect transformer, then a great deal more data about the transformer would need to be supplied: it isn't). Hence, because the efficiency of the transformer in this question is less than 100%, that must be because a secondary current is flowing in the load, the details of which we do not know - or indeed need to know. (ii) Transformers are rated in terms of their product of volts and amps: called VA. They are NOT rated in terms of watts, since the manufacturer cannot assume that the load on the transformer secondary will have a unity power factor. (iii) When a transformer supplies current to a load, its on-load efficiency is the ratio of (VA)out to (VA)in. (VA)in primary VA; (VA)out secondary VA. Solution. Let the primary current Ip; let the secondary current Is. Let the primary voltage Vp; let the secondary voltage Vs. Let the efficiency n. Then we have: (VA)in Ip X Vp Ip X 17.7 (VA)out Is X Vs Is X 120. (VA)out n X (VA)in. so: Is X 120 0.92 X Ip X 17.7 i.e.: Is/Ip (0.92 X 17.7)/120 0.138/1 ? Hence, the secondary current is 0.138 that of the primary current. HTH, Skywave.

Q:Hope to engage in the transformer predecessors to answer. I hope you help me introduce a little more recommended information better: I have seen the 220kV power transformer minimum 63MVA, the largest 250MVA, there is no such specification is not clear, it is estimated that small and small is not where to go, and then big is not where to go for reference The

Q:how transformer came to know that it has to draw lagging current during summers: A transformer on open circuit is just an inductance and that will draw a small lagging (magnetising) current in that operation mode. On load, the phase of the current drawn will depend on the load. If the load is capacitive then the transformer may well draw a net capacitive current. The small inductive contribution due to the magnetising current will still be there but may be subordinate to the load. The season is of no significance.

Q:What is the normal color of the transformer oil?: transformer oil are produced using the appropriate refining process, the color is shallow, generally light yellow, according to GB / T 6540 method to measure the color are below 1, and some oil color close to the water white. Oil in the use of the process, due to oxidation will produce acidic substances or sludge (sediment),

Q:I am looking for a transformer with an output of 6 volts, and 1.8 amps, or any transformer that can run that cycle. Please, let me know. I've been looking for months now, and cannot find anything. Please help. Where would I buy it? Lowes?: If you don't find it you have got to make it. This is a common transformer. Probably you are finding difficulty with it's current rating.

Q:Transformer oil filter method: 2, vacuum oil filter to ensure that there is a certain number of power, taking into account the size of your transformer, oil pillow position level, the oil filter is too small may not go oil cycle 3, the oil circulation from the oil pillow on the opening of the valve, where the best open after the bandaged, to prevent other debris in the filter oil fall into the transformer oil pillow. 4, filter oil after a certain time, take oil samples. Qualified to stop the oil filter, add the oil inside the oil can be closed after the oil pillow upper check valve. The transformer can be powered by one night after standing.

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
