The magnitude of the transformer magnification is closely related to this power value
Aug 12 , 2021
The power of a three-phase meter is mainly determined by the current specification and model of the three-phase meter and the voltage required for on-site work. If it is a DC power meter, the power P=I current*U working voltage*3, let us give an example below. Transformer If the current specification and model of a three-phase meter is 40A and the working voltage on the spot is 380V, then the powe...

The higher the Q value, the lower the loss when winding the coil
Aug 12 , 2021
Let’s first talk about the definition of inductor quality factor Q Coil The Q value is the basic main parameter to consider the inductance. It refers to the ratio of the inductance exhibited by the inductance to its equivalent circuit loss resistance when the inductance works under a certain frequency of AC voltage. The higher the Q value of the inductor, the smaller its loss and the higher the ef...

Analysis of Magnetization Curve of Ferrite Core for Transformer
Jun 18 , 2022
Ferrite is a material that is relatively cheap in magnetic materials, and has good magnetic permeability and magnetic saturation strength, so it is now used in many current transformers, and in open-close current transformers, it is often based on customers. Therefore, we choose ferrites of different materials, such as PC40 and high-conductivity ferrite. We know that PC40 has a certain magnetic pe...
