Q: New on the transformer reported to stop, how to do,: 2. The time limit for reducing the capacity of electricity shall be determined according to the application made by the user, but the shortest period shall not be less than six months and the maximum period shall not exceed two years; 3. In the period of reduction, the power supply enterprises should retain the user to reduce the capacity of the right to use. Users require the resumption of electricity, no longer pay the power supply discount; more than the time limit required to restore electricity, the new equipment or capacity should be handled; 4. In the period of reduction within the requirements of the resumption of electricity, should be five days ago to the power supply business for the resumption of electricity procedures, the basic electricity from the date of unsealed; 5. After the expiration of the user and the new equipment, capacity users, two years may not bid to reduce or suspend. Such as the need to continue to handle the reduction or suspension of the reduction or suspension of part of the basic capacity of electricity should be calculated at 50 percent.

Q: how do i work out the voltage output of the second winding on a transformer if i know the Primary voltage is 35v and the first winding has 355 windings and the second winding has 4500 how do you do this ?thanks: Assuming that the transformer is designed for a primary voltage of 35 or more, then you can simply multiply the applied primary voltage (up to the design limit) by the turns ratio and this will give you the output voltage. In this case: output voltage 35 x 4500/355 444.

Q: i have the 240V AC to 12V AC step down transformerwhen i connecting directly to 240V line the output is higher at about 16Vi need only 12V for my circuithow to get the exact amount of output voltage?: Put a load on its output to reduce the peak voltage. Try 60 ohm resistor rated 5W. If not lower down into 12V, then try 24 ohm rated 10W.

Q: S11-1250kVA transformer oil capacity how much: S11-1250kVA transformer oil capacity is 550kg, the pressure of the relevant information will be marked on the nameplate, the nameplate has the relevant parameters.

Q: I heard that a transformer is like a ratio device for amps and volts, but I know there must be more to it. How exactly does it work, and what happens when it doesn't have enough current, but enough voltage?: reliable question. to respond to your question, no it wouldnt paintings like that. Transformers substitute AC voltage not DC present day. the way it truly works is that the AC enter creates a magnetic container in the different edge, coming up present day and voltage. in spite of the shown fact that it truly is proportional to the windings on each and each coil. in case you wind one coil on the enter to each 5 on the output, you have created a a million:5 transformer. you put in x voltage and get out 5x. before everything this appears like unfastened means. yet you're actually not elevating present day and voltage. certainly means would desire to stay the comparable. means volts * amps. hence, in case you enhance the voltage, you shrink the present. The strobe mild circuits interior cameras substitute a a million.5V AA battery into approximately 1000V. the present in spite of the shown fact that, is plenty smaller.

Q: Hi - I have some questions for any electrically minded people out there!I have a low-voltage 12v transformer, as pictured here:: It makes no difference at all which wires you connect on either side of the transformer. Both wires will be AC on each side. Transformers can short (blow the fuse) or they open (don't work). To much load is usually the cause of problems.

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: Yes, if you're already reading an electromagnetic potential from a particular lead to ground and you ground it to a good ground, you will certainly cause some heating of the transformer which may cause a breakdown of insulation and failure of the device. The purpose of grounding is to prevent a person or animal from becoming a conductor between the unit and the ground. (While dry human skin is quite a good insulator, damp or sweaty skin becomes an excellent conductor. To safely ground your transformer, scratch the paint from the area immediately around one of the mounting holes. Using a bolt, or screw with a washer, attach a green or bare conductor to the frame of the device and ground the other end to a known ground. If the unit will be located in a potentially damp area, you might consider going a step further and installing a Ground Fault Interrupter between the power source and the primary coil of your transformer. GFIs have become fairly cheap in recent years and are available at any good hardware store. Just follow the simple directions that come in the box to replace the current duplex receptacle. You can even tap power for your unit downstream from the actual receptacle.

Q: What is the critical load of the economic operation of the transformer?: Transformer manufacturing and economic operation Transformer economic operation depends not only on the economic operation mode, but also depends on the transformer manufacturing level. According to the transformer often load can be divided into four cases: one is often at full load or close to full load operation of the transformer; the second is often running in most of the transformer; third is often running in a few half of the transformer; Load or no load operation of the transformer. The current factory factory transformer, the economic load factor is mostly 40 ~ 60% range, the above four types of load are not fully adapted, especially for full load or light load operation of the transformer loss rate is great. Therefore, the proposed production of four types of transformers, the economic load rates were 90%, 65%, 40%, 20%. Each unit can be based on the load of the transformer to select the appropriate economic load factor of the transformer. In this way, the power units of the transformer can run in the economic operation area, you can save a lot of active power and reactive power 5. 2 Transformer update and economic operation The purpose of the equipment update is simply not to eliminate its tangible wear, but also to eliminate its intangible wear. Only by constantly updating the way can we fundamentally reduce the equipment loss, improve efficiency, improve the technical backwardness. Update the transformer will inevitably bring active power and reactive power savings. But to increase investment, there is also a recovery period of the problem. Transformers are not damaged after the update, but aging to a certain extent, but also have a certain value when you can update. Transformer manufacturers of different types, different capacity of the transformer life are provided, generally 20 years. The use of units in accordance with the provisions of the years to extract depreciation equipment, and the transformer update

Q: I want to start watching Transformers Prime on TV, but I want all the backstory of just THAT universe, because i know there are MANY Transformer universes from Bay to Generation 1 to this. I just want to know what to read and watch before watching this series. Thanks!: Transformers Prime is set in a new continuity family, launched recently by Hasbro and also includes the War for Cybertron video games. It's really complicated, but in short, you only need to know that you do not need to watch, play or read any previous Transformers material to watch this series. Even the War for Cybertron games, which are supposed to be in the same continuity family, actually clash with the events of the TV series to the point that they're effectively a separate continuity. I myself have not played the game and it's perfectly fine. Also, I've provided links for the ultimate Transformers wiki so that you can do research on whatever aspect of the Transformers universe that you want. Don't worry, the show is fine to watch from the Darkness Rising: Part 1
