S9-M.R-30~2500/10KV three phase scrolliron core distribution transformer is suitable for distribution system with 10KV.50HZ for industrial and mine enterprise and power illimination.
It confirms to GB1904<power transformer>standard.
- Q:i took it out. on one side of the transformer i have a black and a red im hooking those up to a battery on the other side i have five wires 2 red, 2 white, and 1 blue i dont know what these do or how to get current to them. does anyone know how to complete the circuit???
- You're already dead in the water trying to make a transformer work with DC power. You'll need AC, or at the very least pulsating DC.
- Q:I needto know the full conditions of parallel operation of transformers including details about vector groups.
- I am putting 1 QA for reference. Question If I parallel three 2MVA 22/11kV three phase 50Hz Dyn11 transformers of the same voltages, vector groups and impedances, do I connect all three star points to earth or only one star point to earth? If I want to put a resistance in the neutral connection to earth (NER), do I only connect one which is common to all three or a seperate NER for each? Answer Dear Dario, I will start with the imepdance: every transformer shall have its own because it is there to protect against internal faults as well. You may install only one impedance but that will depend on your protection devices and what they measure, i.e. where you put your CTs and VTs. These impedances must have a disconnect switch. For the first part, it is very general to me but i figure your load is large Medium Voltage motors (a mill), because 2MVA seems little for distribution and a Y secondary in MV is tricky. All neutrals shall be interconnected and connected individually to earth. This is for the case where the only link you have in mind is gone, the whole system will go float; so again, for the first part: all three star points shall be connected. If you're already protected against lightning, then you don't need limitation in surge voltage, i advise not to install a resistor and not connect N to E, i.e. go for an IT system which provides you with two benefits: fault currents are small and it take more than one fault to trip and cause discontinuity to the service,
- Q:Transformers are divided into several. What is the role of each? To be specific!
- Transformer is the instrument that regulates voltage! Transformers can be classified according to their operating frequency, use and core shape. (1) Classification by operating frequency Transformers according to the operating frequency can be divided into high-frequency transformers, IF transformers and low-frequency transformers.
- Q:i would say transformers alll the way
- i like them both even though i like twilight. I still like to watch transformers. I like them both.
- Q:Where is the transformer used?
- Transformers are suitable for applications where the voltage level is to be changed Need to change the impedance to match the front and rear impedance of the occasion It is necessary to increase the current supply as a booster
- Q:If calculating the efficiency of a transformer with different frequencies,how can the frequency be altered? For the experiment the voltage applied will have to be constant, is this still possible? or what quantities will be kept constant? and which will be measured to calculate the efficiency? using PVI to then use %(Pout/Pin)*100 would mean measuring current and voltage, is this the best way?
- properly no rely what engineering considerable you elect, you may desire to take Calculus a million 2, Matrices, Differential Equations, Chemistry a million 2 with labs, Physics a million 2 (Electromagnetism). you do not easily declare your engineeing considerable till the top of Sophmore 300 and sixty 5 days in college. Junior 300 and sixty 5 days is once you would be formally enrolled in a considerable. once you word for college and choose a considerable, you at the instant are not easily enrolled in that considerable and you will nevertheless choose any considerable you prefer. they merely ask what considerable you have an interest in to verify you're taking the mandatory situations on your first 2 years earlier stepping into your considerable in Junior 300 and sixty 5 days. interior the 1st 2 years of taking chemistry, math, and physics, you may additionally take Intro to engineering(CAD), and a brilliant form of engineering classes and electives like Statics, Dynamics, power of fabric, Thermodynamics, Into to electric powered Engineering(Circuits), C++, or Fluids. those classes will help you make certain what direction to circulate in direction of. based on your description, you desire Mechanical or business Engineering. the two deal in convalescing performance of goods, machines, and approaches. the two have numerous math. the two prefer expertise of Physics and the two require you to be good in difficulty fixing.
- Q:What is the meaning of the high voltage side and the low side of the transformer?
- In general, the "high voltage side" refers to the "side of the high voltage side" (high pressure side) "low side" from the power supply to the primary side of the transformer (low voltage outlet) The From the wiring is also basically able to distinguish: high side (into the end) is generally "△" connection, low side (outlet) is generally "Y" connection.
- Q:What is the power transformer, what is the rectifier transformer
- Rectifier transformer is isolated transformer, is often used in the power distribution cabinet to do the power.
- Q:Transformer secondary side is high pressure or primary side is high pressure
- Transformer can be divided into two types of step-up transformer and step-down transformer, the primary side of the transformer is the voltage input, the secondary side is the output. Step-up transformer is the secondary side voltage greater than the primary side, step-down transformer is the secondary side voltage is less than the primary voltage.
- Q:I want to run a electric motor at 6v from a wall outlet. I need to know what wall plug transformer rating I should use to run it. Here is what I have.
- Better stay away from your USB with motors of any sort. The on/off spike could take something out in the computer. If you care about the Router, try not to go much higher than 20 % above rated voltage. The current draw from a motor increases drastically as you double the voltage applied. Simple adapters have only a transformer, some diodes and maybe a capacitor. When trying a higher voltage, try to get a meter in the line to measure the current. If you exceed to rating for the adapter, expect smoke. Try adding a capacitor (say 1000 microfarad rated for 20 volts) [watch the polarity] to the leads coming out of your adaptor. Better quality direct current will make your motor run better. Simple adapters can be voltage controlled by the variable speed controls available for ceiling fans. Some can be controlled by regular light dimmers. Cheap adapters may be available from Radio Shack as returns where someone mashed the jack.
