Q:i m studying about the non linearity in systems and transformer is non linear in nature
You will drive the core flux well into the saturation region with a disproportionate increase in iron losses. The magnetising current (which is normally very small) will also increase strongly and disproportionately. The transformer might still function quite well (although with higher harmonic content in the voltage) but especially due to the high iron loss and also because of the increased magnetising current you would have to reduce its rating quite considerably. These are the effects of non-linearity. The higher voltage you would be applying would also place all the transformer insulation under a higher stress, increasing the risk of an internal short or external flashover. You would in minimum have to subject the transformer to a suitably elevated over-voltage test, which it probably wouldn't withstand. This sounds like quite a big transformer and if there is any danger to persons or to neighbouring installations if an accident (explosion, oil spill or fire) were to occur, you, or the responsible person, could easily be facing a negligence or even gross negligence charge for authorising the change!! I definitely wouldn't sign off on that one!!
Q:SGB10 transformer and SC (B) 10 transformer What is the difference between the two series where the difference, specifically to the 10 type and where the hope that the knowledge of a detailed explanation Thank you
Both transformers are dry transformers. 1, SG (B) 10 is an open dry change, he used the United States DUPONT company's NOMEX insulation paper insulation (high voltage coil, you can see is white, if it is darker that is covered with glass wire The former is American technology, the latter is German technology.) The low voltage coil is a copper foil (there is a B in the model that is made of copper foil). The same is true of B in the SC (B). High and low coils are insulated with VPI (vacuum pressure dipping). The surface of a layer of epoxy resin insulation paint wrapped up. 2, SC (B) 10 model means that the epoxy resin pouring dry change (low pressure is copper foil). The high voltage coil is sealed with an epoxy resin, but the low pressure coil epoxy is hard to pour in, but at the end of the coil is sealed with an epoxy resin. 3,10 is the design serial number, representing the loss standard value. 4, there is a dry change, model SCR (B) 10, he is non-epoxy resin casting package. All with NOMEX paper plus silicone encapsulation is the French technology. This product yield less, better quality. Maybe the price will be higher. You can also look at it. 5, is currently in the country is the three kinds of technology transformers. Epoxy resin pouring products are mostly "F" class insulation level, a few also have "H". SG (B) 10 majority is "H" level. , A few are "C" level. SCR (B) 10 is "H" level. If you still want to know what, you can give me a message.
Q:dear sircan you please tell me the different Between the indoorr and outdoor distributionn transformer 11kv in applications and designwith our best regards
Outdoor Transformer Indoor Transformer - Transformers that are designed for installing at outdoor are outdoor transformers and transformers designed for installing at indoor are indoor transformers.
Q:Can a transformer be used with dc? what happens is a transformer designed for 120v ac is connected to a 120 v dc line?
No, it can't. If it is connected to 120VDC, the output will give an initial pulse that decays to zero and stays there. The input will draw far more current than designed, overheat, and either open up or catch on fire. Here is how a transformer works with AC: The input winding generates a magnetic field (because it is an electromagnet). The field alternates because the applied current alternates. The alternating magnetic field couples into the output winding where it induces an electric voltage that alternates because the magnetic field is alternating. Now here's the kicker. The voltage induced in the output winding is proportional to the rate of change of the fluctuating magnetic field. If the field is static (ie, steady, as is the case if the input winding is powered by DC), then the rate of change is zero and the induced voltage is zero. That's why the transformer can't transform DC. Other interesting facts: The input winding converts electrical energy into energy in the magnetic field that is then converted back into electrical energy in the output winding. The input winding resists DC current based on the winding's resistance. If the input current is alternating, then it resists the current additionally based on the inductance of the winding, and the higher the frequency, the more it resists. A transformer is designed to work on a specific frequency (eg, 50Hz or 60Hz). Operating it at 0Hz (DC) will allow too much current to flow. The higher the applied frequency, the more power the transformer can transfer. Think of it as though the transformer passes a bucket of energy from input to output on each cycle. The more cycles per second, the more energy per second, aka the more power. At 0Hz (DC), it isn't passing any buckets of energy. Hope that helps.
Q:The book said the main transformer power failure operation should first stop the load side after the power side, is to prevent the transformer in the case of multi-power reverse charging. What is the transformer anti-charging here? What's wrong?
You can explain the specific situation, your multi-power situation is what kind of situation, because we have not seen you refer to the "book"
Q:I wanted to watch the transformers cartoons but because there is so many I don't know which to watch first, seconds etc.Can you please tell me in order which to watch?I'm watching Transformers Season 1 episode 1 atm.THANKS
If you want to watch the show that started the whole Transformers, Go on google and look for Transformers Generation 1. That will give you the original transformers cartoon to come out. You can google for a list of them or wiki it. But the List i Got Goes like this. #1. Transformers Generation 1 #2. Transformers: The Headmasters #3. Transformers: Super-God Masterforce #4. Transformers: Victory #5. Transformers: Zone After that starts the beast wars series of transformers then the New Age transformers such as armada,energon, and cybertron, and finally the current airing on cartoon network Transformers: The Animated Series. I personally enjoyed generations one the best, as i watched when i was younger but i hope that helps you out in your search or on what ever you wanted to know.
Q:Rules for the operation of cooling devices for oil - cooled transformers
E, strong oil cycle air-cooled and strong oil circulating water-cooled transformers, when the cooling system failure to remove all the cooler, allowing the rated load to run for 20 minutes, such as 20 minutes after the top of the oil temperature has not reached 75 ℃, then allowed to rise to 75 ℃ , But in this state the maximum time to run no more than 1 hour. ?F, under normal circumstances, the transformer no-load operation, the cooling device two groups of work, a group of auxiliary, a group of spare, the remaining disabled; transformer low temperature, light load, the four groups of work: a group of auxiliary, a group of spare, the rest Deactivated; transformer high temperature, full load, a group of auxiliary, a group of spare, the rest all into work.
Q:Current and Potential transformers both are actually Instrument transformers, which step down or lower down the values of current and voltages for measuring purposes.But I have heard of that both CT and PT specifically are used for stepping up current and voltages at some point of transmission system.if this is correct then can anyone tell where they are used?If not then there are step up transformers for similar uses but my question is why they are not called as CT's or PT's.
Assume the source is our normal house electric supply. Assume that the following loads will work safely for the two voltages. Case 1. The load is impedence type. Then Power is Voltage^2/impedence. Example is our heater load. Hence by manupulation of the impedence, we can manupulate the power output. Case 2. Assume it is a constant horse power motor load similar to our fridge. Adjustment of voltage will not alter the power output. The power output will be entirely decided by the load horse power. But an increase voltage will reduce the input current, there by reducing the heat loss in the load.
Q:10 (6) What is the meaning of 10 and 6 in the KV transformer?
These numbers refer to the voltage, 10 (6) KV transformer 10 and 6 refers to the primary side of the transformer voltage level is 10kV or 6kV. 10 / 0.4 (0.22) KV substation in the number of "/" refers to the transformer primary side of the voltage level 10kV, followed by the transformer secondary side of the voltage level is 0.4kV and 0.22kV, that is, 400V And 220V The primary voltage is the voltage of the transformer line, the secondary voltage is the voltage after the transformer transformer.
