Cast Resin Transformers from SGB

The operative benefits for you, our customer, are the following:

• Thanks to the multi-layer winding principle, high surge voltages and switching

voltages are handled safely.

• Cooling ducts provide thermal reserves and allow for overload.

• The use of glass-fibre reinforced plastics (GFK) in the encapsulated windings

provides resistance to temperature shocks.

• Long service lives are ensured.

With production starting in the late 1970‘s, SGB-SMIT were one of the first manufacturers of cast

resin transformers, thus we are able to offer our customers the benefit of our extensive experience

and know how. This extraordinary know-how is reflected by a especially high quality score, e.g. an

MTBF of over 2,400 years.

It goes without saying that SGB-SMIT cast resin transformers meet all the established

quality conditions: Fire classification F1 • Environmental class E2 • Climate classification C2

And as a matter of course, the product sector Cast-Resin Transformers at SGB-SMIT has been

certified according to ISO 9001 and ISO 14001.

Q:1. diode2. converter3. transformer 4. mercury-arc rectifierpl provide with explanation: obviously (3) transformer All the others allow current in only one direction. And i assume the converter is an AC to DC converter.

Q:I just replaced a light fixture in an apartment complex.I discovered that the bonehead that did the install did not run an equiptment ground when he installed the entire circuit that the light is ran off of (dumb a**!!!!!!!!)Does anyone know if it would be up to code if I where to just drive an 8 ft. ground rod and ground the fixture/entire circuit off of the rod?I have looked everywhere.Cannot find anything in code books.If someone knows where this is in NEC, please include the location.Anybody have any input?: As mentioned the box may be grounded and you cannot see it. If it is not then you must ground it. There is code that will tell you the gauge of the wire that you must use for each circuit. The new code indicates that you do not use a ground rod, but a ground plate. That plate must be buried deep enough that it is in damp soil or it will not work. I am not familiar with the plates, but with the ground rods you need to have more than one and they have to be separated. I have attached a link to the city of Concord code.

Q:Hi we are going on holiday to Brazil and staying at the Super Club Breezes Hotel in Costa De Sauipe where they have 220 v AC but while we are in Brazil we are planning on also visiting Rio and Iguassu Falls where we understand they have 110 v AC. What exactly will we have to buy and take with us so that we can use UK hair dryers, phone chargers and other assorted electrics. Thanks AJ: You'll need one plug adapter and one voltage transformer as well. If your equipment is bivolt, then only the plug adapter is needed.

Q:I cannot see that a electrode would be useful in a generator, is there a way?: According to Wikipedia: An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). There is an example of an electrode used in generators, and all industrial/commercial electrical systems. It is called a grounding electrode. It is a metallic rod that is driven deep in to the dirt, to establish a contact with the background Earth voltage. Is the dirt a nonmetallic part of the circuit? Well, dirt often does contain metals in it, but it isn't dominantly metal, so it still is considered non-metallic. And we normally hope that the dirt isn't part of the circuit, but there is a chance that it can become part of the circuit, and that is generally why grounding electrodes are installed. The grounding electrode doesn't really play an active role in the operation of any of the electrical equipment. It is more of a safety feature, as a JUST IN CASE the insulation on the live wire fails. Suppose the live wire insulation fails, and the live wire contacts the metal structure of a device (that isn't intended to play an electrical role), and you as a human victim touch that metal structure. You are also standing on the ground, and the natural path of electric current from the metal structure to the ground is through your body. Unless of course, a better path is established in advance. And that is what a grounding electrode, and the rest of the grounding system does. It establishes electrical continuity with all metals that aren't intended to be electrically involved, so that any failure of the live wire will trip the circuit breaker before there is a chance that the human gets injured.

Q:I am just a few classes away from getting my Associates in Electrical Engineering. I currently have a Diploma in Industrial Electricity and have been working in industrial maintenance for 12 yrs. and am currently an electrical technician (10 yrs. multi-skilled and the last 2 yrs. strictly electrical due to a job change). I have returned to school to get my AAS in EE, so I would really like to know what possibilities I could expect.: You can get a job as an electronic engineering technicians. You help design, develop, test, and manufacture electrical and electronic equipment such as communication equipment, medical monitoring devices, navigational equipment, and computers. You may work in product evaluation and testing, using measuring and diagnostic devices to adjust, test, and repair equipment. Median annual wages of wage and salary electrical and electronic engineering technicians were $53,240 in May 2008. The middle 50 percent earned between $41,550 and $64,120. The lowest 10 percent earned less than $32,490, and the highest 10 percent earned more than $78,560. Median annual earnings in the industries employing the largest numbers of electrical and electronic engineering technicians were:

Q:i was on the computer and now i feel empty?? im not mad sad i just was on the comp and i felt like this: I don't care what people say, electrical equipment and the energy such equipment gives off is not good for you. Take a few hours to go read a book, take a walk or even just a nap. Then, try limiting your time on the computer to as few hours as possible until you begin to feel better; it took me over a month to get back to 'normal' from a bout of computer-induced 'depression.' Good luck.

Q:Greetings, I've noticed that my electrical power company is constantly sending me a reports on how much electricity I am using with respect to my neighbors, kind of trying to get me to use less energy. I figured that if a company is in the business of selling something, it might as well encourage you to use more than you really need.Why is my utility encouraging me to use less electricity? Is it because they feel there's going to be a backlash against the industry once the word gets out that utilities are big drivers of global warming, and they are trying to do damage control ahead of time.Remember, we live in a capitalistic society where maximizing profit is key to keeping investors happy. I can understand the water company asking me to consume less water, as water is a scarce resource. Coalwe have lots and lots of it. Enough to burn for a few hundred years.: Correct, revenue - expenses profit Building more plants or buying from other utilities is an expense. So, pretend that you are the electric company. Let's call it Jose Electric Company, JEC. So, JEC has to provide electricity to 5 million customers. They use about 1,000 kilowatt hours each per month. That comes up to 5,000,000 customers times 1,000 kw 5 billion kw-hours. If you could get them to cut usage then you would not have to build more power plants. Power plants used to be expensive, now they are very expensive. Your friend, the govt, does not want you to build plants that use coal. They are not keen on other fossil fuels. This year they like solar and portable nuclear plants. Yes, portable nuke plants. Till the political and regulatory environment gets a little more stable, it is easier to cut demand rather than build more production. On the other hand. Notice that within the last couple of weeks that 2 new nuke plants announced their start of new reactors. Looks like 1 was in South Carolina and 1 was in Georgia. It would seem that they have foresight, experience, skills, management and money to make sure supply is there for the demand. We also have enough natural gas to burn in jet driven turbines, many years. Water scarce? Where did the water go? Did it leave the planet? Water problems are logistics and not really shortages, are they?

Q:I have heard, (I can't recall where), that the Earth's natural magnetic field is slowly declining. I have also heard that solar flares can disrupt the operation of electrical/electronic equipment. Would either of these natural phenomena affect the operation of electronic/electrical equipment? Please answer each query briefly, and provide links if possible.: Electrical/Electronic equipment is only effected by something called Electro Magnetic Interference (EMI). The Earth Magnetic field usually does not create this kind of interference. The solar flares on the other hand can produce EMI. However, there are ways you can protect your electrical equipment from the EMI by shielding the equipment from the source of EMI. The thickness of the shield depends on the frequency of the EMI and the conductivity of the metal that is using as the shield. In general, a good conductor metal is the good shield such as Nickel, Silver, Copper, etc. Another way to protect a electrical component against the EMI is using a high permeability metal (hi-mu metal).

Q:By non related I mean like not a minor in another engineering or computer science. I was thinking about possibly business. What do you think would be the best minor that would give me a better salary/job opportunity?: Business would be good for engineers. I majored in business and the hardest part was the math. Being an engineering major you would probably enjoy business. However, if I were you I would save the business degree for the day you decide to get your masters. You will get more out of it as an MBA degree. Why don't you minor in applied math? Since you already have all of those math classes under you belt. If you are a guy looking to meet girls you could minor in psychology, sociology, or communications. This is where all of the girls are. However, you would probably be writing more than you are used to in Engineering. I minored in Sociology and the classes were very interesting. I also found the classes to be very easy as well (if you like to read and write papers that is). It will boost your overall GPA. Also, these type of classes revolve around discussions from the reading and is more socially interactive. This may provide the balance that you are missing from the engineering classes. Minoring in English would also be beneficial for engineers. You know once you start working as an engineer you will be writing reports. I work with a lot of engineers and have found that they are very bright. However, they lack communciation skills and writing skills. So if you are looking to stand out of the crowd you should hone in on your writing and communication skills while in college. Most engineer managers have excellent writing and communication skills.
