Why should the transformer core be grounded? Is it not grounded? What is floatin

1. The metal structural parts inside the transformer are either connected to the live body (high voltage or low voltage) or connected to the grounding point. If it is not, it is called a floating point on the electric potential. When the transformer is running, the potential of this metal piece is uncertain (not grounded, and not connected to high-voltage or low-voltage potential), which is technically called a floating potential. His existence will cause hidden dangers of transformer failure. Therefore, there must be no structural parts with floating potential inside the transformer.
2. The transformer core is a metal structure of this type. It is not connected to high voltage or low voltage inside the transformer. It is an independent metal carrier, so it must be connected to the ground so that it has the same potential as the ground. Of course, the iron core can only be grounded at one point.
