basically a matter of the magnetizing inductive reactance which is inversely proportional to frequency. You want to keep the magnetizing current low to minimize power loss and avoid saturating the core. The higher the frequency, the lower the required inductance for a given inductive reactance and magnetizing current, thus the smaller the required core and/or number of turns on the windings.
Magnetizing current is a normal parasitic byproduct of the transformer inductance and the applied voltage level and frequency. The amount of power that can be transferred through a transformer is usually limited by the transformer winding resistances and is unrelated to the magnetizing current. Thus core size goes up at higher power levels due to larger required wire size, not due to any core limitations.
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
Yes the transformer effects the incoming frequency supply. This frequency is dependent on the core lamination of the transformer the weightier the core lamination the lesser will be the frequency we get and vice verse..
a transformer or inductor or capacitor does not change frequency frequency is controlled at the generating station with the speed of the motor or turbine the number of phases will not make a difference an inductor or capacitor can shift phase up to 90 degrees you can make 3 phase power from single phase power with inductors capacitors and transformers
By using step-down transformer
Transformer capacity (kvA) shall be identical, Both transformer impedance, secondary voltage and frequency shall be identical.
In transformer there is no rotating part.so frequency constant.
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
First we know that transformer is a statical electrical device that transfer electrical energy from one circuit to another circuit with out change its frequency .....it may be voltage or current is change simultaneosuly or separately .... and point is why does not change the frequency in the transformer because the there is no moving part in transformer....As we know that frequency is depends upon the rotation....
In general, the lower the frequency of operation, the more weight must be added to the core laminations to avoid magnetic field saturation. This increases the size and weight of the transformer as the frequency decreases.
The basic function of a transformer is to change voltage levels.
Yes the transformer effects the incoming frequency supply. This frequency is dependent on the core lamination of the transformer the weightier the core lamination the lesser will be the frequency we get and vice verse..
If a square wave is used instead of a sine wave in a transformer, the output power will operate at a different frequency. This will produces varying levels of voltage and amperage based on the wave.
intermediate frequency transformer (ift) acts as a band selective n/w. the ift which is 455 khz is then given to IF amplifiers which is then given to detector.
we cannot use transformer because transformer cannot change frequency . . .
If the frequency is kept the same, you will overexcite the transformer, and it will draw excessive current (similar to inrush currents). Insulation tests are performed on transformers above nominal voltage, but they are performed at higher than rated frequency to keep the volts per hertz roughly equal to prevent overexciting the core.
If the transformer was designed for the specific frequency in use, it will step up or down voltage and current as it was designed to do. Transformers transform how power "looks" by increasing and decreasing voltage and current, while keeping power output equivalent to input (if you ignore the transformer losses).
