Isolation transformers vs. autotransformers: Safety comparison
Transformer safety is always one of our most concerned topics. Today, we will delve into two common transformer types, isolation transformers and autotransformers, and compare their safety during use.
Isolation transformer: structural advantage
The design of the isolation transformer ensures that there is no direct electrical connection between its primary and secondary windings. This design means that even if the secondary windings accidentally come into contact with the power supply, there is no direct risk of electrocution. This is because the isolation transformer transmits energy through magnetic coupling rather than a physical connection, thus providing an additional layer of safety.
Autotransformers: The risk of shared windings
In contrast, the primary and secondary windings of an autotransformer share a portion of the coil. While this design improves efficiency, it also creates security risks. Because if the secondary winding accidentally comes into contact with the power supply, the risk of electric shock increases significantly due to the direct connection of the winding.
Safety comparison: Isolation transformer is better
From a safety perspective, isolation transformers are generally considered a safer option. Its design essentially reduces the risk of electric shock and is particularly suitable for use where a high level of isolation is required. However, this does not mean that autotransformers are unsafe; It is still very practical and efficient in many applications, but it requires more attention to safety measures when used.
Choosing the right transformer is crucial to ensure the safety of the power system. Isolation transformers and autotransformers have their own characteristics, but in applications that require a high degree of isolation and security, isolation transformers are undoubtedly the better choice. Through this in-depth understanding of this video, we hope that viewers will be more informed in choosing the right transformer to ensure both efficient and safe power supply.
