Why can't transformers operate with direct current?
The reason why Transformers cannot work with direct current is that their working principle relies on the phenomenon of electromagnetic induction, and the characteristics of direct current are incompatible with this principle.
How to determine if a dry-type transformer has malfunctioned？
Dry-type transformers, as the core equipment of the power system, require comprehensive fault diagnosis by integrating various methods such as operation status monitoring, visual inspection, and instrument testing. Special attention should be paid to "abnormal signals" (such as sounds, temperatures, appearances, and electrical parameters).
The Benefits of Using Resin Molded Three-Phase Transformer
When it comes to power distribution applications, the importance of finding reliable transformers cannot be ignored. In recent years, resin-molded three-Phase Transformers have gained wide popularity in the industry for their excellent efficiency, reliability, and safety. This type of transformer uses epoxy resin to encapsulate the windings and core, making it an excellent alternative to transformers that use oil or other liquid substances as cooling and insulation media. In this blog, we will carefully examine the functions and advantages of this transformer, highlighting why it is the preferred choice for power distribution applications.
Do you know about oil-immersed transformers?
An oil-immersed transformer is a common type of Power Transformer. It uses oil as the primary insulation method and cooling medium.
Do you have any knowledge about the radius of transformer power supply?
The core influencing factors of the power supply radius
Voltage level: The voltage level of low-voltage distribution systems (such as residential electricity) is low (in China, 220V single-phase / 380V three-phase is commonly used), and voltage loss is more sensitive to distance. Therefore, the power supply radius is much smaller than that of high-voltage systems.

Do you know the main components of an oil-immersed transformer?
The oil-immersed transformer, as a commonly used transformer equipment in the power system, has an additional special component related to insulation and cooling oil on top of the core components of ordinary transformers. The main components can be classified into three categories: electromagnetic core components, oil tank and cooling system, and insulation and protection components. The details are as follows:
The new development trend of ZGS American-style pre-installed substations: Integration of intelligence and greenness simultaneously
The development trend of ZGS American-style pre-installed substations is mainly influenced by various factors such as the industry environment, technological innovation, and market demand, and it shows the following trends:
The function and significance of the transformer oil reservoir
When the volume of the transformer oil expands or decreases with temperature, the oil reservoir will adjust the oil level to ensure that the transformer tank is always filled.
Without an oil reservoir, the fluctuation of the oil level in the oil tank may lead to various negative consequences:
