When the transformer supplies power to the load, the voltage at the load end of the transformer will inevitably drop. Compare the falling voltage value with the rated voltage value, and take the percentage, that is, the voltage change rate（...

The first function of oil immersed transformer oil is insulation. The insulation strength of transformer oil is much higher than that of air. The insulation material immersed in oil can not only improve the insulation strength, but also be f...

Transformers are required in most areas where electricity is consumed. This is not practical. If the output detection is 380V, the high voltage is generally 10kV, and some auxiliary high voltages are 6kV, the transformer is selected accordin...

Abnormal sound of distribution transformer, overheating of distribution transformer, significant change of insulating oil color of distribution transformer, oil injection of conservator or explosion-proof pipe, relay protection action, three...

Traditionally, the power system is divided into four systems: power supply, transmission, distribution and power consumption. By power supply and distribution, we mainly refer to power supply system and distribution system....

American transformer is limited by high voltage, its volume is small, and its performance is far less flexible than that of European transformer. Advantages: the radiation is lower than that of American box transformer, because the transform...

Ral is a color card brand in Germany. This color card is widely used internationally, also known as ral international color card. It is translated into Chinese as Raul color card. Today, Evan, hengfengyou electrical technical engineer, summa...

What is the difference between a voltage regulator and a transformer? The function of the voltage regulator is to stabilize the voltage within the required range. There are two types of voltage regulators, one is AC voltage regulator, the ot...
