Q: I am powering a lighting system with a mixture of SCR dimmers and HID lamps. I am pulling approx 285 amps/leg at 120/208V through a 150 kVA transformer. The 120/208V service coming from that transformer is indicated to be 400A/leg, but it seems to get pretty hot at 285A.: Three phase transformers are given a power rating which is the sum of all three powers on each phase. So 285 amps on each phase at 120 line to neutral (assuming this is how youve them connected) is about 35kva, so about 100kva all up. What is actually on the name plate of the transformer? How hot is 'pretty hot'? Is it running as it was desinged (oil, dry, forced air cooling etc). Also how are your lamps/dimmers wired? The other answer is correct, the dimmers will produce alot of harmonics. The meter your are using to read the current is most likely designed to read a 60hz sine wave, any other stuff there will cause a wrong reading (they usually measure the average value, then apply a correction factor to obtain the rms value. But this factor depends on the wave shape, if its not a sine wave it will be wrong). See if you can obtain a meter that will measure the true RMS current. Transformers of that size are usually heavily over engineered, it should be fine as long as the tempertature doesnt continue to increase, ie to the point where the case is too hot to touch. As the other answer said it is probably rated for continuous operation at about 75 degrees. Id not worry too much as long as the temperature doesnt continue increasing.

Q: I want you guys to tell me if the movie transformers its a good movie or not? Why?Thanks, See Ya!: If you watched it as a kid, it was a great movie, it had all the elements from the cartoon, and stayed true to almost everything(they had to change Megatron, he turned into a gun) And if you never saw it before it is still a great movie, great story, great acting(with a hot Megan Fox) and tons of great action. The effects really make the scenes when they transform believable.

Q: How long does it take to restart the transformer?: (4) power failure operation, the first load side of the switch, after the power side of the switch (multi-side power from low to high stop); first pull the transformer side of the knife, after pulling the bus side of the switch. Power supply operation is reversed. (5) into the backup transformer, the device should be based on the actual location and instructions to determine the load has been taken in order to make the operation of the transformer power failure. Diagonal and 3/2 wires on the transformer, although the transformer has been out of power, but the transformer's heavy gas and differential protection action can still cause its ring side of the switch trip. Should be based on the actual situation and the site of the gas protection to change the signal location or retreat gas out. (6) station transformer does not allow long-term side by side. Can be used to cut low-pressure low-pressure side of the cutting machine, with high-pressure knife cut off the station with a transformer.

Q: Rules for the operation of cooling devices for oil - cooled transformers: C, work or auxiliary cooler failure after removal, should be automatically put into the standby cooler; ?D, strong oil circulation cooling transformer operation, must be put into the cooler, no load and light load should not put too much cooler (no-load state to allow short-term cast). All the load into the corresponding number of coolers should be in accordance with the provisions of the manufacturer, according to the temperature and load switching cooler automatic device should be kept normal.

Q: As a small project I wish to wire a microwave transformer to create arcs in air via use of a wand (and yes I will be taking the necessary precautions but that's step 2) first I need to know a couple things: 1 on the high voltage secondary is it really as simple as take the two leads and put them anywhere near eachother? Would that not create a MASSIVE short circuit? Most of the tutorials I've seen use in series so perhaps that negates it in some way? Or am I reading it wrong? Is there some sort of safe load used? Or does it really arc to itself? And 2 what is a good way of preventing it from overheating (if that is a problem). This will probably be used as a Jacob's ladder or old motherboard destroyer. Thanks so much for the help!: here you go

Q: anyone else see the trailor for this movielooks kinda goodthough, it may be were the transformers are bad guys, i dunno: My friend andrew was an extra in this movie

Q: What is the meaning of the transformer without excitation?: General power transformers are equipped with tap-changer, can be carried out in a small range of voltage regulation to meet the grid voltage fluctuations, as far as possible to the transformer output side of the voltage stability. There are two ways: 1, on-load regulation: it can be in the transformer with load, automatic or manual tap position switch. Because the switch is completed in an instant, so it will not affect the normal operation, that is, once, the second side are not power failure can be carried out under the circumstances. 2, no excitation voltage regulator (sometimes mistakenly said no load voltage regulator): is to be in the primary side and the secondary side are power outages, put the isolation switch to open the case, to ensure that the transformer in the absence of electricity, adjust the tap position , The regulator. 3, in the past, it is possible from the English No Load (no load) or On Load (contained) translated over, said to be no load regulator. This is not accurate, it is easy to be misinterpreted as: the transformer can be in the absence of load (current) when the regulator, without the need to control whether the power side. This is very dangerous, no excitation voltage regulator, it is very accurate, to the transformer side, the secondary side are power, in the absence of any excitation circumstances, to operate. 4, therefore, our professionals must change No - Load to Off - Eirecuit - Tap - Changing.

Q: I just heard from a guy who works with either the electric company or construction that the transformer behind sams club(where i work) caught on fire and its going to be a long term job. The power is out for them, walmart, kohls, and like 10 other large businesses nearby. Anyone have any idea what kinda time frame that would be to fix that? I wanna know if I'm going to be out of a job for a few days or not. Its too late to call and ask. So how long does a transformer take to repair/replace?: If the transformer belongs to the utility company, then they usually have it replaced within 24 hours. If it is privately owned then it could take a week or more.

Q: I can't remember the funny scenes from any the Transformers movies, especially 1 and 2.It's driving me nuts.I saw the third one just last week so I remember a couple of funny scenes, but other than that, no luck.If you can, could you please include a link to a video clip of the scene?Thanks so much! (:: I'll give you scene by scene from each movie that I can recall. I apologize for the lack of videolinks but I'll describe them as best as I can. Transformers: Bobby Bolivia (Bernie Mac) talks about his mom. Oh l love that woman if I had a rock I'd crack you in the head, b***h. Sam gets arrested and interrogated by the cops when Bumblebee runs off to communicate with the rest of the Autobots. What's this new thing they're on? Mojo? Ratchet sniffs the air when introduced to Sam and Mikaela. The boy's phermone levels suggest he wants to mate with the female. Mikaela makes Simmons take off his clothes. He has a Sector Seven t-shirt on underneath. Sam, Mikaela, Maggie, and Glen are flying to Hoover Dam. Rachel: So what did they get you for? Sam: I bought a car, and it turned out to be a giant alien robot. Who knew? Revenge of the Fallen Sam's mom and dad fooling around before their trip in front of Sam. Dad, this is not a rap video. Leo doing his funny dance while Burning Down the House is playing. Anything involving the Twins and Wheelie. Sam's mom. Oh, professor, I'd do anything for an A after eating a hash brownie (LOL! Funniest part of the movie). Simmons strips off his pants and shows he's wearing a Sector Seven cup underneath. Lennox tricks Director Galloway into parachuting off the airplane.

Q: 1. a district 800 + a layer of 500mm2 shopping malls should choose how much capacity? 2. A 315kva transformer has been for a district 600 households electricity, ask there is a 70 households can access the transformer?: 800X8 = 6400KW 6400KWX0.5 (use factor) = 3200KW + 50KW mall = 32500KW (full load operation) Choose three sets of 1000KVA transformer ,, 3000 (KVA) X0.9 (functional factors) = 2700KW · · · · · · · · · · · · · · · · · · · · · · · · · 315KVA transformer for 670 is too small ,,, 670X8 = 5360KW, 5360X0.5 = 2680KW 2680KW / 0.9 = 2977KVA Choose three sets of 1000 phase change
