Q:1000KVA transformer power loss is how much
The gap between the various models is also great, but also with the size of the load. To the S9 parameter is the no-load loss is 1.7KW, which is the same, full load loss is 10.3KW, this load-related. If the transformer is fully loaded, then the power loss = (1.7 + 10.3) X1H = 12 degrees 1 hour. S11 of the no-load loss is 1.15KW, full load loss is 10.3KW, full load run loss of power = 1.15 + 10.3 = 11.45 degrees 1 hour
Q:I think it will. Michael Bay who doing the movie has a history of messing up classics. Godzilla is my prime example. So, what do you think? Transformers the movie: Good or Bad?
Transformers is a 2007 live action science fiction film conceptually based on the Transformers franchise and toy line. The film is directed by Michael Bay with Steven Spielberg acting as the executive producer. This adaptation is the Transformers' first feature film since The Transformers: The Movie in 1986, (though unrelated) and also sees the return of Peter Cullen as the voice of Autobot leader Optimus Prime, over 20 years since the original cartoon. The film has had intense Internet speculation, and has a release date for July 4, 2007.
Q:KW how to know how much transformer?
You said KW, it should be refers to the active power of the. Select the transformer depends on the nature of your load, and what type of load, such as emotional load, or resistive load? If it is purely resistive load (very little), then the transformer capacity to choose the same as your load can be, if it is emotional load, then according to the formula S × cosφ ≥ P can be. Calculated after the election can be selected transformer, the general will leave a margin of more than 5%.
Q:Do you know what that show is called where there are these dinasaurs, and there are good oens, and bad ones, very similar to transformers.The dinasaurs transform into robots. Whats it called?
I remember a purple dinosaur too. I'm pretty sure it's called Beast Wars, and it is a version of Transformers. If I remember correctly, the Autobots and the Predacons landed on Earth and in order to survive they took form of existing life forms on Earth. The Autobots took the form of mostly animals, but the Predacons landed near some dinosaur fossils so some took the dinosaur shapes. Megatron was a purple-ish T-Rex, and I think there was a pterodactyl one too. Optimus Primal was a gorilla and they had a cheetah and a rat in the Autobots.
Q:Transformer Transformer Principle
Summary of words: Electrosagnetism. Magnetic electricity. Its basic principle is: a coil and the secondary coil around the same core, when a coil power, the alternating magnetic flux in the core, (magnetism) the alternating magnetic flux through the secondary Coil, according to the law of electromagnetic induction, will produce alternating electric potential in the secondary coil, (magnetic power) due to a secondary side of the coil turns, therefore, the secondary side of the voltage will not wait.
Q:I know there is decepticons and autobots but i remember hearing somewhere that in the cartoon version transformers there was anothere group
i think ur talkin abt unicron, When Primus first created Cybertron, he created a crew of thirteen living robotic beings to man him. These beings, in imitation of Unicron's transformation abilities, were able to change their forms into the likeness of vehicles, weapons, and machinery. They were the first Transformers, and seven were Primes. Many of the thirteen died in a cataclysmic first battle with Unicron, where he was sucked down into a black hole and trapped along with his acolyte known as The Fallen, one of the thirteen who had turned against his brothers and joined Unicron. Of those that survived, many abandoned their original functions and were lost to time. Only Vector Prime was known to still be following the path he was set upon by Primus. The ThirteenEdit Prima, the first Matrix-bearer and first Transformer born from Cybertron, leader of the 13. The Fallen (originally Megatronus Prime), the guardian of entropy Alpha Trion who can see the past, present, and future, and who holds the Covenant of Primus and the Quill Vector Prime, the guardian of space and time Nexus Prime, the guardian of the multiverse's Rarified Energon, capable of splitting into 5 smaller robots: Skyfall Landquake Breakaway Topspin Heatwave The Liege Maximo, the ultimate evil counterforce of good An unnamed female warrior Logos Prime (possibly) The Last Autobot (possibly) Maccadam (possibly)
Q:I am seeing the TRANSFORMERS series now for the 1st time, unfortunately I do not have all the EPISODES. Megatron turns to Galvatron, What Happens to OPTIMUS PRIME?? Does he change too?? Who is GALAXY CONVOY???What is the Final Episode of the Series, Who will be Alive at the End and Who is Defeated?? Please explain me in Detail,,,In Depth.Thanks in Advance.
In the Transformers movie from the 80's, Optimus Prime is killed by Megatron. He gives the mantle of leadership to his 2nd in command (another large tractor trailer truck named Ultra Magnus) During his death though the mantle is handed to Hot Rod for a moment and the audience sees that he is the true leader it was meant for. At the end of the film he received the Mantle and becomes Rodimus Prime. Megatron however in fighting Optimus was gravely injured along with several other Decepticons. On the return flight to Cybertron, it is decided that they need to rid the ship of any unnecessary weight so as to make it possible to return (all the way) to Cybertron. Megatron is one of the last thrown over board and StarSCream becomes the new leader. As Megatron floats through space, he comes across the path of Unicron who is the largest transformer (Moon/planet size). He gives Megatron life again in the form of Galvetron. Only catch is he must serve Unicron. His first order of business of course is to kill Starscream (takes about 10 seconds). Convoy is Optimus Prime's name in Japan's version of the show. Additionally, in the series you are currently watching, Optimus is brought back to life twice and remains with them as leader through the end of the series. The series has had many lives so there is no definitive end to the characters yet. I could give you a ton of other info, but I think this is what you needed.
Q:Can a transformer alone be used for amplifying audio signals ? If yes how ?
Transformers are AC (alternate current) devices and if 60 Hz is supplied to the primary windings 60 Hz will be produced at the secondary terminal. The transformers transform voltage and current at the primary to voltage and current at the secondary by magnetizing a mass of iron in their cores. The magnetic cores may not respond efficiently to very high frequencies (transmission frequencies) but might respond to audio frequencies (loud speakers employ magnets and coils of wire). If a suitable audio signal was applied to the primary coil a transformer might be used to step up or step down the voltage of the supplied signal while reversing its phase, however power (P EI) would remain nearly constant.
Q:Are you agree with me that Transformers The Movie (1986-Cartoon) is better than Transformers (2007) in terms of it's storyline, dramatic and character's behaviour?Transformers (2007) is such a great movie but i think i prefer 1986's cartoon. I always make me want to cry.
i like the 2007 TRANSFORMERS
Q:1.Transformers are normally used to step up or step down alternating voltage or current. May dc also be used to step up or step down voltage or current? Motivate your answer?2.The supply voltage of a step down transformer is 240 volts and the winding ratio is 4,8 : 1. If there are 2000 turns on the primary winding calculate:2.1) The number of turns on the secondary2.2) The primary current when the secondary current is 15 A3. Calculate the secondary voltage of a transformer with supply voltage of 415 volts, the winding ration is 36 : 14.Can an Autotransformer be used to step up pulsating dc current? Motivate your answer.
1.strictly NO.DC cannot be used at all to step up and step down using transformer if you read the working of transformer,it works on the principle of electromagnetic induction. i.e. it depends on change of flux with time. it can only happen in ac voltages not in dc ones because in dc the volatge is fixed but in ac it changes with time and flux and current are directly proportional. 2. 2.1)it is step down transformer. so number of turns in primaryno. of turns in secondary NpNs 4.8/12000/Ns Ns2000/4.8 Ns416.6777 but no of turns needs to be an integer so Ns417 (round off) 2.2)Ip/IsNs/Np IpIs*Ns/Np 15*2000/417 71.94A 3) 415/Vs36/1 Vs11.53V 4) Yes. such transfomers are called pulse transformers.
