S11-M.R- 30~2500/10KV three phase scrolliron core distribution transformer is suitable for distribution system with 10KV.50HZ for industrial and mine enterprise and power illimination.It confirms to GB1904<power transformer>standard.
- Q: 50KVA transformer maximum load is how much?
- 50KVA transformer can bring the maximum load is, 1.45 * 50 = 72.5A or so
- Q: I am working on a lengthy project and have one little area that I am not sure how to answer. I need to know how to size a transformer for a building. Does anybody know the equation or method for doing this? The service coming in is 480Y/277V and the step-down is to a 240/120 single phase panel. Any help is great! Thanks
- buildings come in all sizes. Some use a lot of power, perhaps because of lots of machinery. Others use a much smaller amount. So you need to calculate or estimate the amount of power the building will be using. If you know the square foot total and use of the building (industrial, office, etc) there are probably tables that will give you a guess. One 240/120 panel for the entire building? That implies a very small building, as must buildings distribute 3 phase 208 volts, and have numerous subpanels. .
- Q: What is the meaning of the high voltage side and the low side of the transformer?
- High voltage side called high side of the low voltage side called low side
- Q: Transformer total circuit breaker rated current 380v, rated current 1000a, the rated capacity and output power how to calculate, I did not learn more points
- KVA is apparent power, kW is active power. inspecting power: S = 1.732UI = 1.732 x 0.38 x 1000 ≈ 658 (kVA) Active power: P = 1.732UI cosφ = 1.732 × 0.38 × 100 × 0.8 ≈ 526 (kW) AC power, power divided into three kinds of power, active power P, reactive power Q and apparent power S, at any time these three power always exist at the same time. ????? The cosine of the phase difference (Φ) between the voltage and the current is called the power factor, denoted by the symbol cosΦ, where the power factor is the ratio of the active power to the apparent power, that is, cosΦ = P / S ????? Three power and power factors cosΦ is a right-angle power triangular relationship: two right-angled edges are active power P, reactive power Q, and oblique edge is apparent power S. ????? S? = P? + Q? S = √ (P? + Q?) ????? Apparent power S = 1.732UI ????? Active power P = 1.732UIcosΦ ????? Reactive power Q = 1.732UIsinΦ ?? ????? DC = P = UI = U? / R = I?R
- Q: Hi:I found a 10,000 WATTS STEP UP TRANSFORMER.Following are its characteristics: 1- 10,000 Watt Maximum Capacity Heavy-Duty Continuous Use Transformer. 2- Converts 110/120V upto 220/240 VoltsWhat will be its input?I means which battery or Generator i have to use for its input?Is it good idea to use that transformer to supply electricity to 1 house?
- If you live in USA or Canada,electricity voltage is 115v. You may connect the two wire that mark with 120v into the house electric main power panel,use a 10 amperes breaker to protect your house power source if the transformer that you found is defective. The output shall produce 240v,it is good to run a stove or dryer,because they need 240v. Some country house does not have 240v source. If you live in other country that using 240v power source. You may use this tranformer to produce 120v to run some electronic device that buy from USA. Or you may join the 120v coil with the 240v coil in series to produce 360v .
- Q: Why the provisions of the maximum temperature of the provisions of the transformer 65 °?
- Most big oil temperature increased load, the transformer internal fault, there is lack of oil performance security risks. So we do need to limit oil temperature and protection tripping. Small capacity (630KVA less and outdoor) often do not have the oil temperature protection. I have the original table 800KVA overload (secondary current 1500A), top oil temperature to over 90 degrees ......
- Q: I check the voltage between x1 and x2 I got 120v but between x1 and ground on primary I got 40v and between x2 and ground on Primary I have 50v, if I connect x2 to ground won't it short the transformer? Thank you
- I am thinking that your incoming power is 208 volts and you want to convert to 120 volts. If i haven't made myself look foolish, you merely need to use your x1 and x2 wires to continue on as your 120 volt power source. Cap off, do not connect/use the other connections involved on your multi tap transformer. If I have the idea wrong.never mind what i said. To ground the transformer, truly grounded? you need to connect the metal, unpowered shell to a ground. If you mean make a neutral/ground, you don't.
- Q: A 630 kVA, 11kV/400V transformer. Rp, Xp, Rs, Xs, Rc, and Xm are given. How to find secondary and primary? Do I need to calculate the total impedance referred to the primary and secondary or can I calculate currents without it?
- Given its capacity this is almost bound to be a three phase transformer. You need to know the connection of the primary and secondary windings (Y or Δ) to determine the windings' currents. You can basically calculate the rated currents from the kVA rating and voltage without using the impedances, eg. Ip primary rated current 630/(11 x 3 x √3) which assumes a 3 phase transformer with a Y-connected primary. Edit: If the capacity value is totally unreliable then there's no way you can find the rated current with only the other values you give. You need the load impedance as well.! This applies whether it's a single or a three phase unit I'm afraid. Why do you bother me with useless data? If you do this kind of thing to your employer in later life you'll rightfully get scalded!! On top of that you don't even initially say please or later apologise for such a gaffe.
- Q: I am very dissapointed because i lovvvve transformers but how can the movie go on without her? I know i know. the show must go on. but cmon. i hope they pull it off., does anybody know why megan fox isn't going to be in it.
- Because she said the director wanted to be Hitler, and a bunch of other mean things about him in interviews. Three men who worked as crewmen wrote a huge letter about how horrible it was working with her, and how spoiled rotten she is. The director apologized, and despite the comparison to Hitler, he stated he was still hoping she'd be in the third one. But, she once again went into an interview complaining about how hard he was to work with, so he cut her from the movie. So, basically, it's her own fault. Plus, she can't act, so it's not really going to be that much of a loss. I just hope he can pull it off considering one of the main points to the second one was Sam telling her he loved her.
