- Q: Electrical Machinery, electrical machines, transformers
- you are going to could desire to look OFFline for city of beginning to your Srodka branch. you're able to be able to discover that tips of their Naturalization papers and in Church documents (examine the bride's parish first). i could additionally recommend accumulating information on all of the Srodka who settled on your section and the father and mom of the married into the family individuals for the earliest era. There may well be a city given of their documents that promises you a beginning element.
- Q: For my proposed new aluminium extrusion factory I ve the load of 250 kw heater and 670 HP of motors.Whats the kva rating of the transformer I should go for?Pls advice.
- Your connected load is about 250 kW plus about another 700 kW (from the motors when taking into account efficency and Power Factor). So the total connected load is just under 1000 kw. This 1000 kw is about 1 MegaWatt ( MW). A MegaWatt is 1000 kW You want to oversize your transformer, to account for added load at a later time as well. If I was ordering the transformer, I would be looking at one to cover at least a 1.5 MW. This would be roughly a 1,500 kVA transformer. You could order one slightly smaller, and add cooling fans which come on at max loads to cool down the transformer and increase its kVA rating. Because you have a large motor load, you will likely need the full 1500 kVA unit, because of the Power Factor issues with motor loads. BTW --- there may be a 1 year lead time on ordering a transformer that size.
- Q: Hi, thanks for reading my question. I'm an electrician with some basic knowledge of electricity but this is puzzling me. In the USA, a single transformer on a pole means split phase. Three transformers on a pole means 3 phase. What does two transformers mean? Is it split phase with a high leg?Thanks
- In my area there are sometimes 3 or four transformers on a pole. This is a residential area though and a lot of the houses use electrical resistance heating. Looking at the transformers on the nearest pole I see see two wires output and a ground cable coming from each transformer. The transformer coming to my home is single phase 240 volt ( 120V on each hot line). The transformers are rated at 50 kva, so I'm assuming four 50 kva transformers was probably cheaper and more flexible than using one 200 kva transformer.
- Q: How can we figure out which side of transformer is primary which one is secondary by measuring resistance ? I know that the side where input or supply is provided called primary from where the output is collected is called secondary side in both step-up step down transformersAnd, how can we troubleshoot a bad or a good transformer by measuring its resistance on both sides i.e. primary side secondary side ?thanks
- While you can try measuring winding resistance on both the primary and secondary sides of a transformer with a digital voltmeter or an older volt ohm meter, the value is so low a fraction of an ohm most meters can't measure it correctly. What you can do is look for different wire sizes, the step down transformer will have larger diameter wires on the secondary side of the transformer ( smaller AWG) than on the primary side (larger AWG). A step up transformer will have larger diameter wires (smaller AWG) on the primary than the secondary. Again it is almost impossible to use an ohm meter to determine if either the primary or secondary winding is shorted. This is most likely found by applying power to an unloaded transformer and measuring the excessive current draw.
- Q: 440 volts should be as dangerous as 11,000 volts because a transformer does not dissipates power it just converts voltage into current, my question is if the power at the secondary region is the same why it is said that it is not as dangerous.
- volts give jolts amps gives cramps
- Q: 500KW load should be installed how much transformer?
- Mainly to see what the load, if it is home lighting electricity, according to the 0.9 power factor and 20% of the margin, you need to be equipped with 500 / 0.9 / 0.8 = 694.4, you can take 750 kilovolt capacity can be. (Consider the future expansion of another operator), if it is with the motor and other load-based, due to power factor and start the current reasons, at least 900 kVA more appropriate. If the drive is more than 200 kilowatts, the starting current is very large, you need to put a larger margin or the motor using the buck mode (increase the investment cost).
- Q: What are the specifications of the transformer capacity?
- Select the transformer capacity, to the existing load as the basis, appropriate consideration of load development, select the transformer capacity can be determined in accordance with the 5-year power development plan. When 5 years of power development is clear, little change and then the load is not less than 30% of the transformer capacity: ?? ?SN = KS ΣPH / (cosφ η) ?? ?Where: SN - box change in 5 years required configuration capacity, kVA ΣPH - 5 years old with financial calculations, kW KS - at the same time, generally 0.7 to 0.8 Cosφ - power factor, generally 0.8 ~ 0.85 Η - transformer efficiency, generally 0.8 ~ 0.9 ?? ?According to the formula generally KS = 0.75, cosφ = 0.8, η = 0.8 ?? ?SN = 0.75ΣPH / (0.8 × 0.8) = 1.17ΣPH ?? ?Example: a district in accordance with 50W / m2 design, then ?? ?PH = 50 × 19200 = 960kW ?? ?SN = 1.17 x 960 = 1123 kW ?? ?So the district selected three 400kVA transformer.
- Q: I have a transformer with serial number T.K.K EHT 66001 S-2. I confused with input (primary) wires. it has 5 wires (white red brown yellow and blue). which wires is used for 220 vac?? please help.
- It looks like you MAY have an auto-transformer, ie only one winding. Off hand, I would say the white is supply live and blue the common return. If you measure the DC resistance of White to all the others and record reading. Then red to all others as above and same with brown, yellow and blue. The pair with highest reading Should be the primary, it doesn't really matter which is live or neutral, as long as you take the return of the secondary to the neutral. The other 3 wires will give you 3 different voltages with respect to neutral, however the EHT in the serial No. May indicate Extra High Voltage, which is not 220v. by any stretch of the imagination. Is there no information whatsoever on the transformer itself? Clear as MUD I know, but I'm not good at explaining things. Your meter should be at the lowest range, as this is DC resistance you are measuring, not AC.
- Q: I hate feeling the need to justify myself, but I've seen a lot of answers telling askers to do their own homework. I'm trying to do so, but can't find any equations in the book relating power to voltage as well as turn number. Is it PviN? I've just seen Pvi, but that wouldn't apply to multiple loops. This is for ideal transformers by the way, so power for the secondary and primary coils is the same right? But are their vi's equal, or their viN's?The primary coil of a transformer has 200 turns and the secondary coil has 800 turns. The power supplied to the primary coil is 400 watts. What is the power generated in the secondary coil if it is terminated by a 20-ohm resistor?
- The turns ratio is 4:1 of the primary. The power supplied to the primary is 400W. So regardless of anything else, in a ideal transformer, 400W is available on the secondary. But voltage will be 4x higher, current 4x smaller, than the voltage and current in the primary. Disregarding all that, if there is 400W of power flowing in the primary, then 400W will be being dissipated in the 20 ohm resistor. Watts in watts out, but secondary load (resistance) controls the wattage. There is no way to tell the output voltage and current, without knowing the input voltage and current. But whatever they are, the product of voltage x current will be 400W, in this instance.
- Q: i think transformers, iron man is like just a man made siut transformers are the real deal.
- If you're asking me what I think is the better filmit's Iron Manhands down! Jon Favreau did an outstanding job! What made Iron Man such a good film were the performances of all the actors involved in the production, the direction, the special FX, etc. (has there ever been a more perfect comic book adaptation?). Also, the film was more grounded in reality than Transformers. I grew up reading the comics and Favreau did an excellent job of taking the abundant source material and making a credible but wholly entertaining movie that appeals to a wide audience. The live-action Transformers moviesuwell, let's just say it disappointed. The animated film from the 80s is superior. Besides, Michael Bay is a pathetic excuse for a movie director. I can't believe he was tabbed to do Transformers in the first place and I'm not happy he's directing the sequel (Lord, why are they putting so many people in this filmI thought it was supposed to be about the Transformersthe robotswho cares about the people?!). If you grew up a Transformers fan like I didand I mean from the beginning back in the early 80s, then you would understand that Bay totally upset the Transformers mythos for his own ends. Yeah, the movie was successful, blah, blah, blahbut it failed to measure up in the minds of many old-school fansand the sequel will likely disappoint, too. As for what would win in a battle, yeah, the Transformers would likely win, though given Tony Stark's resourcefulness, I'm sure he could design something that would negatively effect them. He designed a Hulk-busting Iron Man armor in the comics. Still, we're talking different universes here and never the twain should meet. Iron Man will likely surpass Transformers in total box office receipts and given its critical endorsements (93% positive on Rotten Tomatoes) as compared to Transformers lack of positive reviews (57% Tomato meter rating -- certified rotten!), that makes Iron Man THE winner in my book.
