Q:does anybody know what Transformers 2: Revenge of the Fallen is going to be about? Like what is the whole plot, or storyline?: Sam Witwicky (Shia LaBeouf) discovers something about the origins of the Transformers and their history on Earth. The evil Decepticons need to capture him for information. The climactic battle takes place at the Giza pyramid complex,where a temple is located within. Lorenzo di Bonaventura explained the film will show the Transformers who visited Egypt before the pyramids were built, and all our heroes end up here because of the Decepticons' masterplan. Furthermore, Egyptian hieroglyphs resembling helicopters and other present day vehicles in real life will be explained in the film as being depictions of those ancient Cybertronians who visited Earth. I also read that Mikaela Banes will be Sam's girlfriend who cannot afford to attend college with him.

Q:I haven't seen Dark of the Moon, but I recently got OBSESSED with Transformers. Please don't spoil anything, but I'm curious, how do they incorporate the new chick, Rosie, Huntington-Whitely, in the movie? Do they ever explain where Micheala went(Btw- I KNOW what happened to Megan in real life.that's not what im asking lol) So yeah, thanks!Bq: SAY OPTIMUS PRIME IF YOUR A GIRL TRANSFORMER FAN:)Bq: Do MOST girls like Transformers, or is it mostly guys who like it?: I think ir's mostly guys (partially because of Megan Fix and that other girl who replaced her). A lot of girls do like it though. I like the concept, it's pretty cool. However, I think they could have chosen a way better actor than Shia LeBoufe.

Q:If defects of one phase transformers can be improved by 3 phase transformer,then why not a 4 phase transformer used: What I see in the other answers look basically correct. There is a video on the General Electric website where a researcher tried transmissions of many types; all the way up to twelve phases. As already said; the advantage is quickly lost above three. Try the Edison Tech Center, Lionel Barthold, and also Steinmetz. For Reference.

Q:Three-phase transformer how to calculate the current, ah, the formula is?: Calculation formula and empirical formula of transformer secondary current Three-phase transformer current calculation formula I = S / (root number 3 * U), where U is the transformer line voltage, KV Transformer Current Experience Port Algorithm: Primary Current I ≈ S * 0.06 Secondary Current I ≈ S * 1.5 For example: a 500KVA transformer to calculate the current and secondary current, with the current formula I = S / (root 3 * U) I = 500 / root 3 * 10 = 500 / 17.32 ≈ 28.8AI = 500 / root 3 * 0.4 = 500 / 0.69 = 724.6A with the transformer current experience calculation formula: I = 500 * 0.06 ≈ 30A I = 500 * 1.5 = 750A Transformer operating load requirements For example: a 800KVA10 / 0.4KV transformer, according to the first and second current calculation, a variety of load current is how much? Solution: Primary current I = S * 0.06 = 800 * 0.06 = 48A Secondary current I = S * 1.5 = 800 * 1.5 = 1200A Low load: Primary current I = 48 * 15% = 7.2A Secondary current I = 1200 * 15% = 180A Reasonable load: primary current I = 48 * 50% = 24A Secondary current I = 1200 * 50% = 600A Full load: primary current I = 48 * 75% = 12A Secondary current I = 1200 * 75% = 900A

Q:Hey I was just wondering if the Nintendo DS version of the Transformers:Revenge of The Fallen game still had the Create-A-bot feature where you can customize your own transformer or if you had to play as the movie characters?: Well, it sort-of has a create a bot feature, but not quite. In the beginning of the game, when you get your transformer as a protoform and once you get to do actual missions, you get to choose out of only three types of vehicles: A light but fast car, an all evened out sports car, or a heavy armoured tank (sort of like another game). However, you can only chose one because you are stuck with that form for the rest of the game. HOWEVER,with energon you pick up fighting other enemies and scanning computers or machines, you can customize stats (attack, agility, defence, ranged attacks, health, and regeneration of health) an customize your robot with different weapons. The game is not a wander-around game like its predecessor, but challenges are available. I guess after you beat the game or when going throughout levels, you play as transformers such as Starscream (beginning of Decepticons) or Optimus Prime (beginning of Autobots).

Q:best movie i everr seen, bein a transformers fan as a kid, this a whole nother level god damnn: I was pissed It ended way to soon!?!?!? I realize it was a rather long movie but after 20 years I needed another few hours. I desperatly await a number two, And they better make it.

Q:How to test a Current Transformer (CT) ? thanks in advance: Yes, Current transformers can produce dangerous voltages, but I don't think they are properly loaded with an ac milliamp meter. If the primary has 1/2 turn and the secondary 5000 turns, the turns ratio is 10,000:1. One millivolt drop in the primary produces 10 volt ac in the secondary, but the volt meter loads the primary somewhat, so the voltage is somewhat less. A calibration curve can be made of ac current verses ac voltage for the particular volt meter, possibly up to 1000 volts ac, which may represent several thousand amps. Neil

Q:I have a National refrigerator which runs on 110 volts . Since the local voltage supply in my country is 220 volts, my refrigerator has been powered by a step down transformer for the last many years and it was working fine. But now the transformer overheats, emits smoke and burns out. I have got it rewound many times but the same problem persists and the transformer burns after a few weeks . What might be the problem?: You need to determine the actual load from your refrigerator, and compare it to the rating of the transformer. Most step-down transformers that one human being can carry without strain are rated at perhaps as much as 1,000 watts. Which is enough to handle the typical refrigerator while it is running, but not, perhaps, when it starts. A typical refrigerator uses between 700 and 1,100 watts, with a surge of between 1,400 and 2,200 watts when it starts. So if your transformer is marginal, and the unit is running more (summertime) or the door gasket is worn or anything similar, you could be overloading your transformer. You also state you have had it rewound - unless the rewinder uses the proper gauge wire, wrapping material and stabilzes the new windings with the correct varnish and epoxy, a rewind will not begin to last as long as the original. And if he/she shorted you a few coils, you will get the correct ratio - but not enough capacity. Just as a general rule-of-thumb, when it comes to motor-loads such as heavy appliances, if you need to use a step-up/down transformer, it should be rated at least at 200% of the steady-state load of the unit. 250% is better. Good luck with it.

Q:Electrical Machinery, Electric Machines, 3-phase transformers: A cluster mounted bank of three 1? transformers has several advantages. - Reduced inventory levels since 1? transformers used for residential customers can be cluster mounted for 3? applications. - The standard 1? transformer in the US has 120/240 V secondary. The secondary windings can be connected to allow the cluster mounted bank to provide 120/240 V 3?, 4-wire or 120/208V 3?, 4-wire. Most 3? transformers only offer one secondary voltage. - If a 1? transformer fails, you can replace just that one, not scrap the whole bank. - Each of the 1? transformers weight substantially less than the corresponding 3? transformer. This allows a line truck to hang transformers where a 3? transformer might need a crane. - Cluster mounted transformers provide better loading on a single pole. Some utilities will cluster mount three 500 kVA 1? transformers on a single pole. Try hanging a 1500 kVA 3? transformer on one pole. - For smaller loads, or in rural locations, only 2? primary is needed to furnish 3?, 4-wire service using two 1? transformers connected with open-wye primary and open-delta secondary. - For 120/240 V 3?, 4-wire service, the lighter and power transformers can be selected to optimize the kVA of each transformer depending on the amount of 1? load being served. -------------------------------------- The advantages of a 3-phase transformers are: - Reduced labor to install since you do not have to wire the secondary connections. - Installation requires less skill since the crew does not have to understand additive and subtractive polarities, how to wire head-to-tail, etc.
