Power transformers are important electrical equipments in a power system, and they are the foundation for ensuring the basic operation of power supply. The development of the economy continuously increases the demand for electricity, and the demand for using power transformers continues to increase. The demand for energy consumption is also increasing, but it is

Electricity is an indispensable and important resource in our daily life, and electrical substation, as an important component of the power system, undertake the important task of power transmission and distribution. in this post, we will comprehensively analyze the definition, classification, and role of electrical substations. What is an electrical substion An electrical substation refers

When a power or a distribution transformer is first put into operation, a phenomenon called excitation inrush current occurrings. Although this inrush current is not so destructive as a short circuit current, the duration of excitation inrush currents is in several seconds, compared with fault currents. The frequency of excitation inrush current is much higher than
