Transformer input power how to ask?
- The significance of no - load power factor of power transformer
The power transformer is likely to run without load, while the low power factor will increase the grid supply voltage. When the power transformer is unloaded, the no-load current is mainly used to establish the transformer core excitation and provide the excitation loss. The excitation current is part of the current current is reactive current, the general design, the power transformer power factor is low.
When the power transformer winding side of the application of sinusoidal AC, the magnetic field is also sinusoidal changes in the magnetic field. However, the core of the transformer is a non-linear magnetically permeable material, so the field current that produces the magnetic field must be non-sinusoidal. Generally appear as "steeple". Figure 1 for a single-phase transformer no-load current waveform and its harmonic spectrum.
Transformer no-load operation, the output power is zero, no-load power is equal to no-load loss. In the case of loss of fixed, the smaller the no-load current, the higher the no-load power factor. Therefore, the power transformer no-load power factor is higher, the better the no-load current is better. Increasing the no-load power factor is one of the main technical research directions of power transformer manufacturers, and reducing the no-load current is an important technical means to improve the no-load power factor.s
Transformer Current Calculations?
- Given its capacity this is almost bound to be a three phase transformer. You need to know the connection of the primary and secondary windings (Y or Δ) to determine the windings' currents. You can basically calculate the rated currents from the kVA rating and voltage without using the impedances, eg. Ip primary rated current 630/(11 x 3 x √3) which assumes a 3 phase transformer with a Y-connected primary. Edit: If the capacity value is totally unreliable then there's no way you can find the rated current with only the other values you give. You need the load impedance as well.! This applies whether it's a single or a three phase unit I'm afraid. Why do you bother me with useless data? If you do this kind of thing to your employer in later life you'll rightfully get scalded!! On top of that you don't even initially say please or later apologise for such a gaffe.s
Why do people use transformers?
- 1.It okorders
does anyone remember Beast Wars? the originial transformers?
- yes it was related they changed them into beast i loved it 2 then they redid transformerss
Can someone explain transformers for me please?
- The voltage is transformed up to thousands of volts and low current for minimum heat loss in the wires. Then down to low voltage at high current to the neighbor hood.s
Transformer question (physics)?
- A transformer works from the expanding and collasp of a magnetic or inductive field. Without the expandin or contracting field, no lines of flux are cut. What is possible instead is to use a chopper circuit and convert the DC to AC run it through a transformer and then rectify the AC back to a pulsating DC and then filter it back to pure DC.s
Where is the transformer used?
- You ask more general, there are many kinds of transformers, 1 is the power transformer, it is 10,000 volts drop to 380,220 V commonly used low pressure for us to use. Small transformers are 220V voltage reduced to household appliances used when the operating voltage rectified as electrical power. High-frequency transformers are generally used as switching power supply pulse output transformer. High-frequency signal transformer only a few turns of the coil, the transmission of high-frequency signal. Simply say this kind of bar, a wide range of various types of transformers.s
