If the traditional concept judgment method is applied, the transformer core grounding belongs to the working grounding, because it is required for work, and it is not grounded during work, and it will not cause direct damage to the human body.
The iron core and other accessories of the transformer in operation are in the magnetic field around the winding, and a certain voltage is inevitably induced. When the induced voltage exceeds the discharge voltage to ground, the transformer will discharge internally. In order to prevent the internal discharge of the transformer, The core should be grounded, so I think it is working ground.
