Q: Transformer ONAN?: ONAN refers to the natural cooling of oil. Common have the following cooling methods: Oil immersion (ONAN); Oil - air - cooled (ONAF); Forced oil circulation air conditioning (OFAF); Forced oil circulating water cooling (OFWF); Forced to guide oil circulation air cooling (ODAF); Forced to guide the oil circulating water - cooled ODWF).

Q: If the primary circuit of a transformer is connected to a power source and the secondary circuit has a light bulb, will the light bulb turn on and stay on when the power source is turned on? Or will it turn on for a few seconds and then turn off?This question's been bugging me because I think because transformers are usually wired through AC that the bulb would only turn on for a few seconds and then turn off, but then shouldn't current be constantly flowing so it would stay on?Thanks for and clarifications.: Umm, is the power source AC or DC? You are right, transformers usually use AC. Is it not using AC in this example? You didn't say. If it's using AC, the light bulb will stay on. The current actually switches on and off, but so fast you don't see it. Well, normally, for household 60Hz AC power. But who knows with this mystery power source. It could be 1Hz AC. If it's using DC, then it will come on for a short time (a few seconds? I don't know). Yes, current is continually flowing through the primary circuit, but after a while no current will be flowing through the secondary circuit where the light bulb is connected. It takes change in current in the primary circuit to induce a current in the secondary circuit.

Q: I work in the power plant, today there is a task is to charge the lighting transformer, I would like to ask the next. What does it mean to charge the transformer? What does this charge mean? What is the use of? Thank you: There is a megger, that is, shake the table, with a handle, used to measure the electrical insulation meet the requirements do not,

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: 500KW load should be installed how much transformer?: According to the power factor of 0.9 and 20% of the margin, you need to be equipped with 500 / 0.9 / 0.8 = 694.4, you can take 750 kVA capacity can be. If it is with the motor and other load-based, due to power factor and start-up current reasons, at least 900 kVA more appropriate. If the drive of the motor more than 200 kilowatts, start a large current, you need to put a larger margin or the motor using step-down start mode.

Q: Transformer total circuit breaker rated current 380v, rated current 1000a, the rated capacity and output power how to calculate, I did not learn more points: Kva is apparent power, KW is active power. inspecting power: S = 1.732UI = 1.732 × 0.38 × 100 ≈ 65.8 (Kva) Active power: P = 1.732UI cosφ = 1.732 × 0.38 × 100 × cosφ

Q: 1. Which type of connection would be the best to use at the beginning of a power transmission line? Which connection would be the best to use at the end of a power transmission line? Explain.2. In wye delta and wye wye transformation, what line voltage should be applied in order to have all transformer windings operating at their rated voltage?3, how do you calculate the percentage of the line voltages?: 1. unsure you would need to read up on that there are plenty of books on power distribution I get the feeling an explaination wouldnt help you without a bit of research first 2. power transformers are manufactured to a certain specification eg 11,000 in 415V out, the output voltage is dependant on the ratio of windings 3. if the turns ration is 1:100 ie if the primary winding has 1 turn and the secondary winding has 100 turns then the voltage on the secondary will be 100 times that of the primary. (not sure if i have answered your question but i tried!)

Q: I was wondering which comic is the best read for an ongoing series about the the Transformers? It can be old or newMarvel, Dreamwave, or iDW. I was just curious because I have been a huge fan of the franchise since the first set of figures and generation 1 cartoon series but never read a single comic about them (which is actually very weird considering I am a huge comic geek) and just wanted to check one out.: transformers are crap why do you read them?!?!?!?!?!?!

Q: a house's two furnaces are not working. the pilot lights are on. The lady's brother said there is no voltage at the thermostat. where does the 24 v come from? a transformer ? where?: there will be no Reference to the 24 volt ground at the thermostat so checking for voltage there is a bad idea. some ware in the control circuit there is a transformer. the pilot light does not require 24 volt to remain on. look at the schematics on the inside of the access door to help you locate the 24 volt source. on an older furnace you do not need any voltage to light your pilot light. you could have a bad fuse

Q: actually I've many questions :) I've opened many mobile chargers and I didn't found the usual (bulky) transformer . I found only a small transformer and I think it called smps transformer.1- I can't understand how bulky transformers can be replaced by small ones! what is the idea ?2- are smps transformers connected directly to 220 volt like the bulky transformers ? if no, what is the design of the circuit that makes small transformers are able to be connected to 220 volt ?3- do smps transformers make a voltage drop like the bulky transformers ? or they have another job ?4- some smps transformers have 4 pins and the other have 5 or 6 pins, I know it should have 2 pins for input and 2 pins for output, why some of therm have more than 4 pins ?Thanks in advance, I hope i'm not bothering you because of my many questions :): Notice the diodes on the board connected to the 220 vac pins. The ac voltage is converted to dc, high voltage dc. There is a small high frequency transformer on the right of the board. A high voltage transistor switches the high voltage dc through the transformer (chopping the dc basically makes the dc an ac voltage). The secondary of the transformer is low voltage ac, which is rectified to dc. There is a feedback circuit so that an increased load causes more current through the high voltage side to maintain a constant output dc voltage. It is possible the extra transformer windings are due different methods of driving the transformer, ie, push pull like some audio circuits. Other configurations include forward and flyback designs all requiring different winding connections. If the power supply requires several output voltages, additional windings are required for the secondary windings. The reason the transformer is small and light for the power transferred across it is that the frequency is so high, meaning less metal core is needed to transfer magnetic energy. At 50 Hz, a massive core is required to store magnetic energy for a relatively long time versus at 30,000 Hz, energy doesn't need to be stored for long at all.
