- Q: Single bus sub-section for power distribution, transformer with a prepared and dual-use how to understand
- One with a preparation: a transformer to run, another cold standby. Dual use: two transformers are running, each other hot standby.
- Q: An AC generator, originally designed to provide a peak output voltage of ± 155 V at a frequency of 60 Hz, is required to provide a peak output of ± 340 V at 50 Hz. If the generator is connected to a transformer with 200 loops in its primary coil, how many loops should there be in the secondary coil in order to provide the required output?Using the formula Np/VpNs/Vs I get 439 coils, but this is too easy for a 6 mark question and doesn't include the change of frequency. I have no idea what to do and need some help :(
- Transformers cannot change the frequency of an electrical signalperiod. It requires more sophisticated electronics to do that. Perhaps your instructor is confused.
- Q: How long does it take to restart the transformer?
- If the transformer is shut down for a month or on hold, the trial is stopped for more than 6 months before the commissioning? A: The transformer shut down for a month, before the resumption of power transmission should be measured insulation resistance, qualified to be put into operation.Post or outage for more than 6 months of the transformer, should be done before the insulation resistance and insulation oil pressure test Dry and cold areas of irrigation and drainage dedicated transformer, the suspension period may be appropriate to extend, but not more than 8 months
- Q: 440 volts should be as dangerous as 11,000 volts because a transformer does not dissipates power it just converts voltage into current, my question is if the power at the secondary region is the same why it is said that it is not as dangerous.
- I haven't a clue as to who told you that. The lower voltage would tend to hold you to the wires, where the higher voltage would push you away. The only real difference is that the higher voltage could arc to you, where the lower voltage at the same distance would not.
- Q: I'm getting a transformers game and idk which one to get. Should I get Transfermors: WFC (War for cybertron) or Transfermors Dark of the moon? Which one is better?
- Out of all the transformers.WAR of CYB was the best!! Because it had no restriction to the movie But I think you should get The New one!! Looks Awesome though but will be expensive.
- Q: I have a 240v-5v transformer for recharging, and it makes an annoying very high-pitched squeaking noise. What causes the noise?
- Normal transformers with iron laminated cores operate at 50-60Hz (50-60 times a second), but transformers in modern cell-phone chargers and PC power supplies require a higher power than would be possible for the given size restraints. A 240v to 5V @ 1A 50-60hz transformer would be the size of a deck of cards and would weigh several kilograms, but if you replace the core of the transformer with a ferrite material (powdered iron) and switch the primary winding at high frequency, say 20Khz or more (20 thousand times a second) the size of the transformer shrinks to the size of a small coin. The ringing sound you are hearing could be caused by several things: 1. It's operated at a near-audible frequency, like 19Khz (not very likely) 2. It's under very high load condition and it's struggling to meet the power requirements and as a consequence the duty cycle of the PWM has increased which can make a chirping sound. 3. It's defective or dying, and it's having a hard time regulating the output voltage and it's excessively modulating the PWM. 4. You are young and young people have better than normal hearing in the higher end of the frequency range and you might be hearing a harmonic of the higher than audible drive frequency. Hope that answers your question :)
- Q: i heard that there is an electric transformer used in single phase electric furnace and other applications , its benefit is to get more balanced current load from the three phase system to feed a single phase load.i need to know how its can transform three phase supply into single phase supply, and if it can be used in reverse matter i.e can it deliver a three phase power from single phase supplythank you in advance
- First off: No, a transformer cannot change Single to Three phase. However you can run single phase equipment on three phase power by simply using 2 of the 3 hot lines. Depending of the voltage requirements for your machine you may need to buy a buckboost transformer to get the voltage to the correct opperating voltage of your machine (ie. a 230 v three phase input will come out at about 208 when used as single phase). If you need a conversion from single to three phase, look into buying a Phase converter. Depending on where you get it, they can be as easy as 2 lines in 3 lines out. Installed in a matter of minutes. I also recommend staying away from what is called a static phase converter. They are machine specific so if you ever change or add on it wont work. Get a Rotary one. It works with everything. Hope that helped. Good luck.
- Q: Hi i'm considering starting to read comics. transformers comics to be exact. i live in ipswich so i walked into my local store (central city comics) there was alot to choose from and i know that there is loads of transformers comics out there I need some advice on starting a collection
- just okorder
- Q: Hello,Recently, my air conditioner broke and I hired a man to come fix the machine. Unfortunately, he did not help my situation and possibly made it worst.Initially, he informed me that my transformer was broken and so said that it needed replacement. However, when he replaced the transformer, both the transformer and the circuit board blew out. Now, he's making me pay, not only pay for his services, but also for the two additional parts. My question is: Is is possible that the circuit board caused this issue? Or did he mess up on the wiring and blow both parts out, by mistake?I just need to know, so I don't pay for something, originally not of my cause.Thank-you.
- The Sandshark nailed it. Tell your handy man he's on the hook for the 3rd control transformer AND the 2nd circuit board. Then tell him to hit the bricks. Now do what you should have done in the beginning; call a qualified, COMPETENT technician.
- Q: hey all , i have 2 phase welding machine fed from 30A 3 phase circuit breaker , at high loads above 40A CB cut off the Supply . the problem is i cant change the CB size bcoz it Contrary to legislation in the country . Can i used scott t transformer to balance the load at the main 3 phase ?
- When you say you have a 2 phase welding machine, that is not enough information to answer your question with a reasonable margin for success. If your welder is indeed a two phase machine, where the phase angle relationship between phases is 90 degrees and not 120 degrees, and you have a three phase service whose phase relationship is 120 degrees between phases, it is possible to build a Scott T transformer bank that will give you a 2phase 4 wire system. You will need two transformers. One of the transformers will need a center tap on its primary winding brought out and the other transformer will have to have a tap at 86.6% of full winding voltage brought out of its primary windings. Also you will only be able to get about 58% of the nameplate capacity from the transformers for the same reasons you get 58% from an open delta transformer connection for three phase. These will be special made transformers, unless you are winding them yourself, and will be expensive. I suspect they and the special connections you will have to make, will exceed the cost of a new 3 phase welder. Last but not least, if indeed your welder draws 40 amps per phase using a three phase circuit you presently have, other alternatives present themselves. Such as a larger three phase service to allow for the 40 amp load. Also you might consider at least one transformer with a center tap primary and the second one without the 86.6% tap. The secondary will be slightly out of balance due to the higher voltage on one set of secondary (about 14% higher) but it may work for the welder. Hope this helps, Newton1Law
