Top rated dry type electrical transformers supplier: Power Quality and Distribution Transformers – The efficiency of distribution transformer substations is significantly affected by power quality. These transformers, which are critical components of the electrical distribution system, convert high-voltage electricity into lower voltage levels suitable for end-use applications. The performance and efficiency of these transformers largely depend on the quality of power they receive. Poor power quality, characterized by voltage sags, swells, harmonics, and flicker, can lead to increased losses in power distribution transformers. These losses can be categorized into two types: core losses and copper losses. Core losses occur due to variations in the magnetic field within the transformer’s core, while copper losses occur due to the resistance of the transformer’s windings. Both these losses are exacerbated under conditions of poor power quality, leading to decreased efficiency of the transformer. Read extra info at https://www.canwindg.com/products-20763.
Oil immersed transformers are the most commonly used equipment mainly because of their simple structure and reliable operation. It has faster heat dissipation, uniform conduction, and better insulation performance than the dry-type transformer.Oil transformers are used in power distribution or electrical substations. Their transformer core and coils are immersed in oil, which cools and insulates. Oil circulates through ducts in the coil and around the coil and core assembly, moved by convection.
The transformer coils are referred to as the primary and secondary windings. When applying AC current to the primary winding of the transformer, the transformer coil creates a pulsing magnetic field. The core of the transformer works to direct the path of the magnetic field between the primary and secondary coils to prevent wasted energy.The machine is a very powerful and versatile machine which can wind a wide range of HV coils for distribution transformers using round and rectangular wires. It is fully automatic with paper strip winding.Winding material lnsulated with an epoxy resin -environmentally friendly.
Rising temperature: The capacity of the transformer will decrease as the temperature rises. Therefore, it is necessary to consider the appropriate heat dissipation method and heat dissipation area when designing the transformer to ensure that the temperature rise of the transformer does not exceed the allowable range. Connection method: Different transformer connection methods, such as star, delta, etc., will also affect the capacity of the transformer. For the star connection, the capacity of the transformer can be increased by about 3 times; for the delta connection, the capacity of the transformer is relatively small. Insulation level: The insulation level of the transformer determines the insulation capability and safety performance of the transformer, and also affects the capacity of the transformer. To sum up, the capacity of the transformer is related to factors such as input voltage and output voltage, load nature, temperature rise, connection method and insulation level. When selecting a transformer, it is necessary to comprehensively consider various factors according to the actual situation to ensure the normal operation and stability of the transformer.

The main pillar of the smart grid is the smart substation, which is not only an important hub for power transmission and distribution, but also directly affects the operational and monitoring capabilities of the smart grid through its operational safety and stability. Through the network, information can be exchanged, and the transformer can share information with the process layer and the station control layer. On the premise of ensuring product performance, the integration of monitoring, control, measurement, protection, and metering is designed to achieve the integration of transformer components with actuators, sensors, and transformers.
Insulation level: There are standards for insulation levels. The insulation level of a transformer with a rated high voltage of 35 kV and a rated low voltage of 10 kV is represented as LI200AC85/LI75AC35, where LI200 indicates that the transformer has a high-voltage lightning impulse withstand voltage of 200 kV, a power frequency withstand voltage of 85 kV, and a low-voltage lightning impulse withstand voltage of 75 kV, and a power frequency withstand voltage of 35 kV. The current insulation level of Aux High-Tech Co., Ltd.’s oil-immersed transformer products is LI75AC35, indicating that the transformer has a high-voltage lightning impulse withstand voltage of 75 kV and a power frequency withstand voltage of 35 kV. Because the low voltage is 400 V, it can be ignored.
What causes the transformer to make abnormal noise? Impurities or gases in the oil: Impurities or gases in the oil inside the transformer may cause unstable oil flow or air oscillations, resulting in abnormal noise. Mechanical failure: Mechanical failures inside the transformer, such as equipment failures such as transformer cooling fans or pumps, may cause abnormal sounds. Loose or leaky pipes: Loose or leaky pipes inside the transformer can cause air oscillations or unstable gas flow, which can produce unusual noises. External environmental factors: Factors such as excessive temperature of the transformer operating environment or noise interference may also cause abnormal sounds. Therefore, if the transformer makes abnormal noise, it is necessary to check and repair the transformer in time. The specific maintenance method needs to be selected according to the cause of the abnormal sound and the specific situation in order to restore the normal operation and stability of the transformer. At the same time, during the installation, operation and maintenance of the transformer, attention should be paid to environmental temperature, humidity, noise and other factors to avoid adverse effects on the transformer.
