What is the difference between the inverter and the transformer?
- ★ 1, [inverter]: inverter can change the frequency, [also change the voltage accordingly]. Because, inductive (such as motor) load, in the frequency down, the sense of resistance is also reduced, in order to prevent the current exceeds the rated value, must also reduce the voltage! In the last century just introduced, for the FM, voltage regulator, speed control device is known as the "three V technology" is the reason.
- ★ 2, [Transformer]: As the name suggests, the transformer is to change the voltage of the device. Transformers are typically used at specific frequencies (eg, frequency, or high frequency). As the voltage used to change, the frequency is constant, which is its salient features.s

single phase transformer?
- This is not really a very hard problem but I'm afraid artsupre's solution of using only the turns ratio is a little too simplistic. According to the problem definition, we need to represent this transformer in an equivalent circuit, as a perfect or ideal transformer of turns ratio 10 preceded by a resistance and leakage reactance in series and equal respectively to the R and X values quoted. This shows us that the current will be totally transformed (therefore I2 10 times I1 90 A) but there will be some voltage drop in the preceding impedance. So how to calculate the voltage drop? We need to take the voltage applied to the terminals and subtract from it the total voltage drop across R and X. This is a vector sum since resistance drops are in phase with current but reactive drops are 90 degrees lagging. We normally use complex representation to accomplish these vector summations. In this case the procedure is: Take the current vector as real. Then the applied voltage is 2200(0.8 + j0.6) and the voltage drop across X+R is 9(5.6 + j22) Hence the resultant voltage at the terminals of the ideal transformer (1710 + j1122) 2045 at a leading angle of arc cos (0.836), i.e. at a power factor of 0.836. This voltage of course has to be transformed by the turns ratio giving V2 204.5 at the above power factor.

What are the conditions for parallel operation of transformers?
- 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,s

how to construct a transformer?
- Transformer is a thing which can reduce or increase voltage. In your question, You want to make such a transformer which can reduce the voltage is called a step down transformer. In transformer there are two coils. One is Primary and the rest of them is Second nary coil. Primary Coil is connected with input(220v) and Second nary with output(120v).To get 120v in output the transformation ratio should be 220:120 means 11:6.s
What continuity is Transformers Prime in?
- Transformers Prime is set in a new continuity family, launched recently by Hasbro and also includes the War for Cybertron video games. It's really complicated, but in short, you only need to know that you do not need to watch, play or read any previous Transformers material to watch this series. Even the War for Cybertron games, which are supposed to be in the same continuity family, actually clash with the events of the TV series to the point that they're effectively a separate continuity. I myself have not played the game and it's perfectly fine. Also, I've provided links for the ultimate Transformers wiki so that you can do research on whatever aspect of the Transformers universe that you want. Don't worry, the show is fine to watch from the Darkness Rising: Part 1s
