- Q:I know that if I needed 600 watts at 120 volts that I would need at least 5 amps, but does the step down create a difference in amperage when using a transformer converting the 120v. to 12v?
- 12 Volt Transformer
- Q:A 8000kva transformer can bring the maximum load
- Transformers are best not to run full of the efficiency of remember the best 60 to 80%
- Q:I saw the first one, thought it was great, and the second one was even better. But are they planning on making another one? If so, do you know what its going to be about?IMO, i think it should be about Unicron, yes that would be kool haha.
- hey, they announced transformers 3 before transformers 2 came to theatres
- Q:1. Which type of connection would be the best to use at the beginning of a power transmission line? Which connection would be the best to use at the end of a power transmission line? Explain.2. In wye delta and wye wye transformation, what line voltage should be applied in order to have all transformer windings operating at their rated voltage?3, how do you calculate the percentage of the line voltages?
- 1. The transformers at both ends of the transmission line are normally connected wye with the neutral grounded. This is done to provide a 'zero sequence source' for two reasons a. to provide source of ground fault current to a fault on the transmission line to permit that fault to be detected. b. to constrain the elevation of voltage on the healthy phases of the transmission line in the event of a ground fault In order for that wye connection to work, it is usually necessary that the transformer also contain a delta winding. 2. The voltage should be the rated line-to-line voltage of the winding. 3. The line-to-neutral voltage is equal to the line-to-line voltage divided by the square root of three. I don't understand what you mean by 'percentage of the line voltages'.
- Q:How many different types of transformers are there if anyone can remember from the cartoons?
- well gee i watch the cartoons as much as i can and well from what i remember, the first few episodes from g1 (1984 series) there were like 15 autobots and 18 decepticons (i don't know exactly). And then in the Armada series if you don't include the dozens of mini-cons seen fighting unicron then i'd say only about 8 known autobots and then 10 known decepticons Tidal Wave Tidal Wave. and i didn't get to see much of energon but i suspect that there were a little more then in armada plus a few mini-cons seen here and there and then the hundreds of terrorcons and smaller number of omnicons (thse are the guys that collect the energon)
- Q:I I am looking to buy a 208 to 480 transformer, would I simply buy a 480 to 208 and reverse the input and outputs? it's a 3 phase system and it is being supplied by an 80kW generator, then straight to an ATS to switch power from normal to emergency.
- Yes, a transformer can be used to either step up or step down the voltage. The rating of a transformer is in KVA, so you can load it to the nameplate rating either way. One thing to consider though is your system ground. When you tie your generator feed back through your step up transformer and then to the ATS . The normal power source feeding your ATS is probably a 3 phase 4 wire grounded WYE system, and your step up transformer will probably have a 3 wire Delta primary. You need to be careful, especially if your ATS feeds any single phase loads. In that case, get a transformer with a WYE - WYE winding configuration. Make sure you follow the NEC code recommendations for a separately derived source.
- Q:I need to know how and auto transformer works and how i can get 240 with it thanks in advance and if theres a website thats explains transformers that would be great (: thnx again !!
- An autotransformer (sometimes called autoformer)[1] is an electrical transformer with only one winding. The winding has at least three electrical connection points called taps. The voltage source and the load are each connected to two taps. One tap at the end of the winding is a common connection to both circuits (source and load). Each tap corresponds to a different source or load voltage. In an autotransformer a portion of the same winding acts as part of both the primary and secondary winding. Operation he ratio of secondary to primary voltages is equal to the ratio of the number of turns of the winding they connect to. For example, connecting at the middle and bottom of the autotransformer will halve the voltage. Depending on the application, that portion of the winding used solely in the higher-voltage (lower current) portion may be wound with wire of a smaller gauge, though the entire winding is directly connected.
- Q:I just finish watching Transformers Revenge of the Fallen for the third time. IT was awesome I 'm getting it on DVD and hoping for it to come out as another transformers.
- i think no coz of the fight between megan and the director of thr movie he said he is tired of her already and is not planning to do the next one , unless somebody else direct it
- Q:Current and Potential transformers both are actually Instrument transformers, which step down or lower down the values of current and voltages for measuring purposes.But I have heard of that both CT and PT specifically are used for stepping up current and voltages at some point of transmission system.if this is correct then can anyone tell where they are used?If not then there are step up transformers for similar uses but my question is why they are not called as CT's or PT's.
- Transformers that are called current transformers and potential transformers are designed specifically for instrumentation purposes. They are designed to provide reduced current or voltage signals that very accurately represent the primary current or voltage. They are designed to have a minimal effect on the primary circuit. The are manufactured only in sizes needed for instrumentation purposes. Instrumentation purposes include not only providing signals to meters but providing signals to protective relays and control systems. CTs and PTs may occasionally be used for purposes other than the purposes for which they are designed. I have heard of a CT being used backwards to supply a high current at a very low voltage for some testing purpose. This sort of thing is sometimes done as a temporary measure when more appropriate devices are not available.
- Q:A transformer is used to step down a voltage of 11KV to 220V. Given that the transformer has 3200 turns in the primary, calculate the number of turns in the secondary coil.Another transformer is used to further to step down 220V to 110V. its input current is 3A and the output current is 5.6A. Calculate its efficiency
- Q1. Let the number of primary turns Np; number of secondary turns Ns. Let the primary voltage Vp; secondary voltage Vs. Then fundamental transformer theory gives us: Vp/Vs Np/Ns. So: Ns (Vs/Vp).Np i.e.: Ns (220 / 11,000).3200 64. The turns ratio is 50:1 Q2. The product of volts and amps is called the V-A of the transformer: volts x amps. An ideal transformer would generate zero losses in transferring electrical energy from primary winding to the secondary winding. But there is no such thing as an ideal transformer: the transference of energy means that some energy gets lost: in heat, eddy currents and hysteresis losses. For this Q, the input VA 220 x 3 660 V-A, and the output V-A 110 x 5.6 616 V-A. The V-A efficiency (V-A out) ÷ (V-A in) 616 / 660 0.933 93.3 % N.B. This is not the same as the watts efficiency, power in ÷ power out: the V-A efficiency does not take power factor into consideration.
