Best dry type electrical transformers producing company: When these harmonic currents flow through a transformer, they can cause increased core losses due to hysteresis and eddy currents. Hysteresis loss is related to the magnetization and demagnetization of the transformer’s core material in response to the alternating current. Eddy current loss occurs when induced currents circulate within the core material, creating local magnetic fields that oppose the main field. Both these losses increase with the frequency of the current. Thus, higher frequency harmonic currents can lead to considerably higher core losses, reducing the transformer’s efficiency and causing it to overheat, which can shorten its lifespan.

What is the capacity of the transformer related to? The capacity of the transformer refers to the maximum load electric power that the transformer can bear. The capacity of the transformer is related to the following factors: Input voltage and output voltage: The input voltage and output voltage of the transformer determine the transformation ratio of the transformer, which affects the capacity of the transformer. The higher the input voltage of the transformer and the lower the output voltage, the larger the transformation ratio and the larger the capacity. Load nature: Different loads have different power factors, harmonic content and other characteristics, which affect the capacity of the transformer. For inductive loads, the capacity of the transformer can be appropriately reduced; for nonlinear loads, the capacity of the transformer needs to be appropriately increased.

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.
To accommodate the needs of grid voltage changes, the high-voltage side of the transformer has taps, which can be adjusted by adjusting the number of turns in the high-voltage winding to regulate the output voltage on the low-voltage side. Rated current (A): The current allowed to pass through the transformer for a long time under rated capacity. No-load loss (kW): The active power drawn when a rated voltage at rated frequency is applied to one winding terminal and the remaining windings are open circuit.It is related to the performance and manufacturing process of the core silicon steel sheet, as well as the applied voltage.
Why do transformers use silicon steel sheets as iron cores? Transformers use silicon steel sheets as iron cores because silicon steel sheets have high magnetic permeability and low resistance. In a transformer, the iron core mainly undertakes the role of conducting magnetic flux. Therefore, the magnetic permeability of the iron core is very critical. Silicon steel sheet is a specially treated steel with very high magnetic permeability, can effectively conduct magnetic flux, and can reduce the loss of magnetic flux and eddy current loss. In addition, the transformer will produce electromagnetic induction phenomenon during the working process, which will generate eddy current in the iron core. These eddy currents cause loss of energy and heating of the core, reducing the efficiency of the transformer. The silicon steel sheet has low resistance characteristics, which can reduce eddy current loss and improve the efficiency of the transformer. Therefore, using silicon steel sheet as the material of the transformer core can improve the efficiency of the transformer, reduce energy loss, and reduce heat generation of the transformer, thereby prolonging the service life of the transformer.
The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When air cooled naturally, the transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation; Because the load loss and impedance voltage increase greatly during overload, it is in non-economic operation state, so it should not be in continuous overload operation for a long time.Welcome to inquiry price for dry type substation transformer.
