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.: From your readings ,the transformer is within it's rating. Power Transformers are usually rated to operate at 75 Deg. C and above. Sometimes up to 95 Deg. C. The data and limit will be on the nameplate. 75 Deg. C is uncomfortably hot. 95 Deg. C. will burn you. Note; SCR dimmers WILL produce harmonic currents that will increase the 'neutral load' well above 'phase load' on 'common neutral' circuits, and might be producing some high frequency heating in that T/F.

Q: When the transformer voltage is a rated voltage, the secondary voltage in the end is how to change with the load, what is the basis for the theory of the way you ask you about the inrush: 2 excitation current characteristics When closing the circuit breaker to charge the transformer, sometimes you can see the transformer ammeter pointer put great, and then quickly return to the normal no-load current value, the impact current is usually called the inrush current, features are as follows: 1) The inrush current contains high-order harmonic components (mainly secondary and tertiary harmonics), so the variation of the inrush current is a steep wave. 2) The attenuation constant of the inrush current is related to the saturation of the core. The deeper the saturation, the smaller the reactance and the faster the attenuation. Therefore, at the beginning of the moment decay quickly, then gradually slow down, after 0.5 ~ 1s after its value does not exceed (0.25 ~ 0.5) In. 3) Under normal circumstances, the greater the capacity of the transformer, the longer the duration of attenuation, but the general trend is the inrush current decay rate is often slower than the short-circuit current attenuation. 4) The value of the inrush current is very large, the maximum rated current of 8 to 10 times. When setting up a circuit breaker to control a transformer, the quick break can be set according to the transformer excitation current.

Q: I know I'm defiantly getting Sleeping Dogs but should I get Just Cause 2 or the new Transformers game based on Generation 1: This is one of those times I hate to say, but its completely your preference here. But if you want a good opinion, ill try giving my best :) Basically Just Cause 2 is a great game. Huge free roam area with many hours of gameplay. It's basically another GTA, except i find the storylines in just cause to be better, and there are more jets and things that are fun to fly/drive around. Its a great free roam game. Fall Of Cybertron is an interesting one to talk about. When I heard about another transformers game I almost threw up. I couldn't understand how anyone over the age of 10 could play those games. But it turns out that they are nothing like the kids toys we are used to. They are lots of fun and are REALLY well made. Fall of Cybertron i really recommend. Had a chat with my friends who run the gamestop near me, and they love it to pieces, one of their favorite games. But in the end you have to choose. Do you want a great free roam, or a great story mode? (linear). My final opinion. Just Cause 2. BUT: As an additional note. I recommend checking out the following games, as I'm sure you will enjoy them: Black Ops 2 Darksiders 2 Dark Souls Battlefield 4 (release wont be until about 2014, but it is official by EA) Also checkout the Wii U. I know, the wii sounds wimpy, they always have. And I still maintain that it is the WORST name for a game console ever. it just sounds weak. But this one will change gaming forever. It certainly beats xbox 360 with gaming power and graphics. Zombiu is currently the most promising title for the Wii U. (which will be out at launch). And Assassins creed 3 has me super excited as well. I personally have already $700 put away on the side to help me with getting the Wii U. Waiting for pre order haha. DONT MISS IT :)

Q: can i use 12VAC 60w transformer for 12VAC 30w (3 10W) light?: Transformer rating is 60 watts ~ don't use total wattage over that. So with your three 10 watt bulbs, that totals 30 watts. Will be okay. You can actually use up to six 10 watt bulbs, or a total of 60 watts max. Been using light bulbs for 65 years !

Q: I wa watching the films and was wondering how the transformers just spawn more and more. For example soundwave made the panther thing then it made the thin robot and all those construction guys too, then they made the huge robot with the balls.: Haha, well from what I remember, the bodies were assembled on cybertron. But that wasnt it. In order to create actual life the transformer needed The Matrix, an orb (or in the live action movies, a slender metal thingy?) which would allow a spark from the Allspark (which is essentially transformer heaven if I remember correctly) to enter the body and give it life. This can also reanimate deceased Transformers. The only other times I remember transformers coming to life in the show, is when the autobots found the Dinobots and somehow brought them back to life? Then there was the world eater, Unicron, who was able to upgrade other transformers. An example would be the transformation of Megatron into Galvatron made possible by Unicron.

Q: I have a standard transformer with 7 wires:2 black2 red2 yellow1 red/yellow stripedWhat connections do these wires correspond to?That is, which should connect internally to the primary coil, the secondary coil, and coil-taps (based on the number of wires, I assume that the secondary coil is tapped).I must determine this in order to connect the wires (externally) appropriately.Any help is greatly appreciated!: Raptor gave good info. I would add just a few points: 1. The high voltage winding usually has the smaller gauge wire. 2. The high voltage (primary) winding also usually has a higher DC resistance and fundamental frequency impedance than the secondary. 3. Be sure to scrape the insulation off the wires before checking the resistance. Many years ago, an idiot I was working with didn't recognize that the wires had enamel insulation on them, and connected the transformer backwards. It was a 480 V / 1 V (or so) instrument transformer. We lost a lot of good equipment and nearly lost people because of that screwup. The recorder saw 2 kV before it died.

Q: Transformer and the middle of what is the difference: Often referred to as the transformer is the frequency transformer, is used to change the size of the AC voltage electrical equipment. It is based on the principle of electromagnetic induction, with the same frequency, between two or more windings, the exchange of AC voltage and current to transmit electrical energy of the static electrical equipment.

Q: A lot of people have been discussing the new transformers film transformers dark of the moon-but how does transformers dark of the moon compare to transformers the movie 1986?For those who have seen all three of michal bays transformers films- and Transformers the movie 1986-which do prefer the new transformers movies or transformers the movie 1986?and more Important why?: The 1986 version has better acting on the part of the voice actors, more caring tragedy, more likable Transformers, very atmospheric, and one of the most tragic death's in the history of robot-kind. The first Transformers movie was stupid but fun. The acting in it was okay, the story was incompetent in the fact that they did not explain as much as they could have, bitchy lead actors, and a pretty epic final battle scene. The second Transformers movie is god awful. It is racist, the story is copied from the first movie, the acting is horrid, the characters are bloated bitches that yell all the time, a horrid villain(s), an overactively preachy Optimus Prime, a horrid Optimus death by unknown Decepticon, Transformer balls, bad dirty jokes, Shi Labeouf in robot heaven, Shi Labeouf having a near seizure, Shi Labeouf's mom gets high, and one of the longest unneeded battle scenes in movie history. The third Transformers movie is a step above god awful, racist towards Asians, the story is copied from the first two, the acting is still horrid, Shi Labeouf is self obsessed, Shi Labeouf is mean (he kicked Bumblebee), the Decepticons are cooler but the Autobots are the same, Optimus is still overactively preachy, a blinking camera during the final fight, a horrid Megatron death, a decent twist with Sentinel Prime, bad dirty jokes, Bumblebee getting tickled, a better and prettier actress than Megan Fox, and one of the worst guest appearances in movie history (Leonard Nimoy). C Y I like the old one better. Which do you like better? Also the new Harry Potter has a 100% from all critics.

Q: Why the provisions of the maximum temperature of the provisions of the transformer 65 °?: Transformers and other electrical equipment temperature limit is determined by the level of insulation materials. Insulation grade refers to the heat resistance of the insulation material used, divided into A, E, B, F, H grade. Allowable temperature rise is the limit of the temperature of the electrical equipment compared to the ambient temperature. Insulation temperature class A grade E grade B grade F grade H grade Maximum permissible temperature (° C) 105 120 130 155 180 Winding temperature limit (K) 60 75 80 100 125 Performance reference temperature (° C) 80 95 100 120 145 In the electrical equipment such as transformers, the insulating material is the weakest link. Insulation material is particularly susceptible to high temperature and accelerated aging and damage. Different insulation materials have different heat resistance, the use of different insulation materials, electrical equipment, the ability to withstand high temperatures are different. So the general electrical equipment is specified in the maximum temperature of its work. You ask the question, the top of the oil temperature does not exceed 65 ℃, is in the case of rated load manufacturers consider a variety of factors to ensure that the insulation material is not damaged by the temperature limit. Under normal circumstances the top of the transformer oil temperature is the highest.

Q: What is a transformer?: Impedance matching: the most common is the electronic circuit, the output and input connection, in order to signal unobstructed, usually using the transformer impedance matching, such as the old-fashioned broadcast, because it is using constant pressure output, speakers are high impedance horn , So it can only match with the output transformer. So, daily life can not be separated from the transformer, industrial production is also inseparable from the transformer.
