1.Product Feature The sz9 on-load tap-changer power transformer is widely applies to urban and rural electric network construetion. The iron core is in ladder shape and changes the traditional piling way of iron core as well as the inner distribution of magnetic way. It also decrease the no-load consurmption, no-load current consurmption and noise pollution all by 20%. The new product applies CAD tool and marked with advanced design, reasonable structure, high quality material. It accords with GB1094-1996 and GB/T64511999. 2.Technical Specification

- Q:27. Two transformer A and B with identical ratings, are to be designed with fux densities of 1.2 and 1.4 wb/m2 respectively. The weight of transformer A per KVA is(a) More than that of transformer B(b) Less than that of transformer B(c) Equal to that of transformer B(d) None28. Transformer action requires which type of flux?(a) Pulsating magnetic flux(b) Constant(c) Increasing(d) Alternating electric flux29. In what capacity transformer natural oil cooling with tubes is used(a) 3000 KVA(c) 500 KVA(b) 30 KVA(d) 750 KVA30. In full rating of transformer is 90 KW at a pf of 0.9, then its KVA rating is(a) 100(c) 90(b) 150(d) 80
- 27. (a) More than that of transformer B 28. (a) Pulsating magnetic flux 29. I do not think there is such a limitation on ONAN transformers. 30. (a) 100
- Q:I remember playing with a brand of shapeshifting car/robot toys in the 80's when I was a kid that was not Transformers. They were popular, had a catchy commercial jingle, and were NOT Transformers, but I can't remember what they were called. Help!
- That would be GoBots.
- Q:do you know when the knew transformers film is coming out ( the year as well)

- Q:i just obtained a transformer from a small ac-dc converter. usually, it converts the 240v ac (let's call it terminals a and c) to 4.5v dc (terminals d and c).what if i connect a 4.5 dc supply to the terminals d and c? meaning that where i would usually obtain the converted electricty, instead, i connect a 4.5 to it, leaving the terminals where i would usually connect to the wall empty. wouldn't the magnetic field step up to 240v?
- TRANSFORMER BECOMES SMOKING IN A FEW SECONDS IF THE 4.5V DC HAS HIGH ENOUGH CURRENT.
- Q:There are lighting transformers, tires and disassembling machine transformers, there is an electromagnetic starter, the tire changer transformer will always burn ah, are used 380V transformer, I have measured the next, when the transformer transformer measurement 391V, electromagnetic Starter average is 396V, nothing to have, has been used very well. But the tire disassembly machine transformer to die, the average voltage of 396V, installed up a few seconds to very hot, but why the other two no matter? Put away Tire disassembling machine Transformer I alone load the air switch voltage ah, 396V, only more than 10 V, the other transformers are not any problems If there is no problem with the secondary side, the voltage reaches the number of volts, the transformer will quickly become hot PS: 396V I was in the 380V where no-load test ah, more than 10 volts are not ah
- This voltage is normal, mainly due to the secondary load is too large, measured under the secondary current. For large capacity transformer can be. No load is not, it can only show that the quality of the transformer there are serious problems, another regular manufacturers with

- 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.
- Q:Hi, I'm trying to build a Jacob's ladder or maybe a Tesla coil. What should I use to get enough voltage? A lot of resistors or a transformer? (Are they also safe for humans?)
- I don't think there is any way to use resistors to increase voltage. Neon sign transformers are the usual choice, but they are not safe for humans. Death is not rare and they likely cause illegal radio interference. Voltage multipliers are likely safer, but the Jacob's ladder arc will be dimmer and shorter. Neil
- Q:I want you guys to tell me if the movie transformers its a good movie or not? Why?Thanks, See Ya!
- First off, I did NOT want to see it. I'm not really into cars and all that kind of stuff. But my husband rented it last night and we watched it. And I will say I was surprised. I actually REALLY enjoyed it. It has a really good storyline and some pretty good acting as well! The effects are incredible too! Overall, it was a very good and entertaining movie! You should definately watch it. You won't be disappointed
- Q:I got stuck in a problem while solving the previous exam question for my courseTwo transformers with unequal turn ratio and unequal ratings are connected in parallel and have the same secondary voltage. How will the load be distributed between them? Hence find the circulating current.I know how to find the circulating current when the secondary voltages are different. But how can there be a circulating current if the secondary voltage is same?And I know about the load distribution being inversely proportional to the line impedance of the transformers, but what will be the change taking circulating current into account?
- If I understand this correctly, then you have this situation, let T1 be the first transformer and T2 the second one The input voltage is connected to the primary of T1 The secondary of T1 is connected to the primary of T2 the secondary of T2 is connected to the load If the secondaries are at the same voltage then T1 secondary voltage T1 primary voltage T2 secondary voltage. This can only happen if the turns ratio of T2 is 1:1, i.e it has the same number of turns on the primary and the secondary. Does that help?
- Q:I will be living in Germany for a while and I'm trying to plug my TV in, as well as one or two other things. The 1000 transformer I have works, but whenever I plug in the power strip to plug in more things than just the tv, it will automatically blow the power in the house and I have to go flip the switch again. Other Americans I know here in Germany do not have this same problem. I need help!
- Only if the power strip is also rated at 3000 volts or higher. Otherwise, definitely not.
