 Q:Transformer 1250KVA Dimensions
 This is not fixed, you list the conventional products, unconventional products can be arbitrarily selected according to customer requirements. There are 300kv, 1000KV, 1100KV, 1150KV and so on
 Q:what is the difference between transformer and transistor?
 Transistor Transformer
 Q:Transformer secondary side is high pressure or primary side is high pressure
 Transformer can be divided into two types of stepup transformer and stepdown transformer, the primary side of the transformer is the voltage input, the secondary side is the output. Stepup transformer is the secondary side voltage greater than the primary side, stepdown transformer is the secondary side voltage is less than the primary voltage.
 Q:From the variable ratio to determine whether the transformer is boost or buck
 110 / 11KV is a stepdown transformer.
110 / 10.5KV is a stepdown transformer.
121 / 10.5KV is a stepup transformer.
Consider the line pressure drop, the state provides a transformer primary winding rated voltage and secondary winding rated voltage.
 Q:50KVA transformer each phase current maximum band
 Transformer output power is apparent power, and active power (KW) relationship: apparent power = active power × power factor. With an average power factor of 0.8, the 50 KVA transformer can be the load power
(50 KVA × 0.8) 40KW of active power.
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, highfrequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

 Q:Transformer confusion.?
 You are confusing VA (power ratings) with transformer ratios 120/16 7.5 :1 3300/120 27.5 : 1 So connect 7Vrms to 16 input to give output 1 52.5V Now connect this 120 (52.5V) output to the 120V input of the 120/3300 transformer The output should be approx 52.5 x 27.5 1444 Volts Use the 16/120 to step up and then the 120/3300 to step up again Take the function generator voltage to its lowest and measure at all points now gradually increase the generator voltage measuring at all points until you get what you want If the voltages are not as you expect then the VA ratings may be a problem Remember to be extra careful with High Voltages
 Q:2500KVA transformer rated current 3608A, how much can be overloaded current?
 Ventilated good circumstances, you can temporarily overload 300A.
 Q:Resistor in series with transformer primary?
 Placing a resistor in series with the primary of a transformer has the same effect as placing a resistor in series with a resistive load: that is, depending on how much current is flowing, there will be a voltage drop across the series resistor which decreases the voltage seen by the primary of the transformer and a corresponding drop in the voltage produced at the secondary. If there is no current flowing, then there is no voltage drop at the primary and no drop at the secondary. For example, your 120:6 transformer produces 6 volts at the secondary with 120 volts applied to the primary. Suppose your secondary load draws 1 ampere, then the power is 6 watts and the load is 6/1 6 ohms. This current reflected back to the primary is 1/20 .05 ampere. The secondary impedance reflected back to the primary is 120/1/20 2400 ohms. So any load in the secondary is reflected back to the primary by the square of the transformer turns ratio: 20^2 400 in this case. 6 ohms in the secondary is reflected back to the primary as 6 * 400 2400 ohms in the primary. So now you can compute the voltage seen by the primary when you place a resistor in series with it. If the reflected load is Rr and the series resistor is Rs then the voltage seen by the primary will be Vp 120 * Rp/(Rs +Rp) and the secondary voltage will be 1/20 of that.
 Q:What Do You Think Of Transformers?
 Transformer is honestly the sickest movie of all time. Are you kidding me. I watched it at least 7 times, and I had to buy the movie when it first came out. Only movie I have ever bought, and I didn't even like transformers that much growing up.
