1. Product Description:
The grounding transformer is usedin the three phase power system with neutral insulation, to provide artificial neutral point.
This neutral point can be directly grounded. It can also begrounded by reactor or arc suppression coil. With a secondary winding,
the grounding transformer can not only provide a neutral point for system but also provide power supply to other parts of system.
2. Product Characteristic:
Special environment should be informed such as altitude, chemicaldeposition, dirt, corrosive media, etc., for dry-type transformers insulation shouldbe provided.
l Mean annual temperature is +20℃and below +20℃(if it’s water-cooling product, the highest daily average temperature of cooling-water is +25℃)
l Altitude is not more than 1000m.
l Installation site should be without seriousvibration, bumps and chemical corrosion,

- Q:Any help much appreciated here, I cannot understand the following formulas at all. If there is anyone who can please explain in very SIMPLE words I would be very grateful. My exam is next week and I am still stumped on the following.VP/VS NP/NS IS/IP ok this bit I understand, but then here are the QAs that don't make sense to me:Q1) A single phase transformer has 1250 primary turns and 200 secondary turns. Primary V I are 230V and 3A. What are the secondary V I?A) 1250/200 230/vs transpose too: VS 200 X 230/1250 36.8V Why has it been turned upside down?230/36.8 Is/3transpose too: Is 3 X 230/36.8 18.75A Why??The following Q I am even more stuck withQ2) Single phase transformer has a rating of 300/230V, 15KVA. What is the full load of primary and secondary?A)S VI Where did S come from?!Ip 1500/3300 4.55A KVA - is this taken as the V? Not I? Is that why Is 1500/230 65.22A it has been reversed? I'm very confused, please can someone help explain this process to me?
- With good intention, I would criticize UR copying of Q2 :} From the primary (Ip) and secondary (Is) currents listed, this transformer's Voltages should have been: 3300V/230V at 15 KVA note the V(volts) after EACH of the two voltages separated by / and that the primary voltage must be 3300 V and not 300 V in order to agree with Ip Is. I don't know where S comes from, but V?I represents the power rating of a given coil (primary or secondary) in a transformer. If the voltage ratio is 3300/230 14.3478/1 then the current ratio must be the INVERSE 1/14.3478 in order that the power on each side (primary and secondary) is the SAME and equal to 15,000 KVA. {this math assumes 100% efficiency which is an IDEAL case for a transformer}
- 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?
- My ONLY issue with the movie is Bernie Mac. I can't stand him. I wanted/knew Ghost Rider was gonna rock but then it turned out that it was the worst movie I've seen in 2007. I watched the trailer after seeing it realized the montage in the trailer were just boring and empty scenes but in the trailer for Transformers, it looks like they have too little time to squeeze so much (good) stuff into the movie. If you've seen the Island and liked it than you'll like Transformers as well. Trust me, Transformers won't be a dissapoint ment but it maybe considered the best summer blockbuster to the majority of Americans. (Since Pirates sucked and Spider-Man could've been better)
- Q:Transformer Uk = 4.5% What does it mean?
- Uk represents the transformer impedance voltage, refers to the transformer short-circuit impedance voltage. The impedance of the transformer (now the standard is called: "short-circuit impedance") standard value with a percentage (per unit value) to represent. General small distribution transformer standard value of 4% or 4.5%.
- Q:Halo4 - love the series, Halo 3 is my favorite, hated Reach. not sure if Halo 4 is more like halo3 or more like reach, will not buy if abilities are includedBlack Ops 2 - BLOPS was my favorite shooter, I will probably get this unless they lower the health to MW2/MW3 standards and they don't fix SMGsTransformers FOC - War for Cybertron was one of the best games I've ever played, but they made Dark of the Moon which was a really bad shooter, and I'm not sure if FOC will be bad as wellWhat would you suggest?
- Definitely Halo 4. I'm kind of burnt out on CoD right now so I'd go with the new Transformers. I agree that War for Cybertron was fantastic. I had really low expectations of it when I rented it, but it turned out to be great! It's online multiplayer is really fun too.
- Q:I noticed that I haven't seen a female transformers, which leads to two possibilities, they were gay or asexual.
- or could asexually reproduce. eh, eh
- Q:I read comments on youtube saying avatar cg looks like computer games.I liked avatar cg. transformers cg looks more real but I don't think movies always have to look more real.
- I disagree. I think the Avatar CGI was way more realistic than Transformers. I liked Transformers too tho. But if u know anything about CGI graphics, u will know that it's harder to realistically render an object with a complex exterior (such as hair, or excessive wrinkles), than it is a smooth surfaced object (such as a metallic robot).
- Q:do you think transformers is cool or not and why?
- I love transformers
- Q:I would like to get my grandchild all the transformer movie dvds but don't know the names of all of them. please help and thanks
- Transformers, Transformers: Revenge of The Fallen, and Transformers: Dark of the Moon(comes out September 30). Hope I helped.
- Q:A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil.A How many turns of wire does the secondary coil have?B When the transformer is running at full power, what is the current in the secondary coil?C The current in the primary coil?I know what equations I would use, but I don't have enough information to use them. Can someone at least set these up and show me how to plug the numbers I have into the correct equations?
- A neon sign transformer has a 350 W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil. Power output Power input Power Volts * Amps 350 13,000 * amps Amps 0.0269 amps current in the primary coil? House voltage 120 volts 350 120 * amps Amps ≈ 2.92 current in the secondary coil? Amp Ratio 2.92 ÷ 0.0292 100 : 1 Wire ratio 100 : 1 A How many turns of wire does the secondary coil have? 50,000
- Q:I am completing an essay on how to improve the performance of a transformer. Please could someone advise me on the problems incurred in transformers and ways that have been designed to reduce these problems. Thanks in advance
- To improve the performance of a transformer, you have to:- [1] Reduce the copper losses, and [2] reduce the iron losses. Copper losses can be reduced by using copper wire of the highest purity; and by using copper wire that has the thinnest possible layer of insulating material on it. These measures, taken together, reduce the length of the wire and therefore its resistance. Iron losses are reduced by using magnetically soft iron in the laminations. This is the type of iron that has a tall and narrow hysteresis loop. Using copper wire with thin insulation (as mentioned above), keeps the windings close to the iron and so reduces magnetic leakage. A third measure is to use very thin laminations and to insulate them with very thin material as this will reduce eddy currents. It is very expensive to build a 99% efficient 250 MVA transformer. The losses in a 94% efficient version, are often cheaper to manage than the extra cost of making the 99% version.
