A three-phase transformer consists of three independent windings, each of which needs to be precisely designed and manufactured to ensure efficient and stable operation under three-phase power supply. Meanwhile, the design of the magnetic circuit system is also a major challenge, requiring consideration of the interaction between the magnetic circuits of each phase to ensure that the transformer can still operate normally under three-phase unbalanced load conditions. The selection of materials is crucial for the performance of three-phase transformers in the manufacturing process. For example, although amorphous alloy materials have advantages such as low loss and high resistivity, their thin thickness, high hardness, and fragility also bring difficulties to the design and manufacturing of transformers. Therefore, how to select suitable materials and optimize the performance of transformers while ensuring their performance is one of the technical difficulties.

Three-phase transformers are essential components in electrical power systems, serving a wide range of applications across industries. From power generation to distribution, these transformers play a pivotal role in ensuring efficient and reliable power supply. Understanding the application scope of three-phase transformers is crucial for engineers, technicians, and professionals working in the field of electrical engineering. In this blog, we will explore the diverse applications of three-phase transformers and their significance in different sectors.

The principle of three-phase isolation transformer basically adopts the principle of electromagnetic induction. It is safe to use a three-phase isolation transformer, which is generally used as a maintenance power supply. The isolation transformer is commonly 1:1 transformer, but it has different specifications. Three-phase isolation transformers are used for changing voltage, lighting, power supply and rectifying power supply, widely applied to industrial and mining enterprises, power plants, airports, high-rise buildings, subways and other places with high fire safety requirements.
