I would like to ask why grounding one end of the secondary side of a transformer does not cause a short circuit to ground

Grounding one end of the secondary side of a transformer does not cause a short circuit to ground, for the following main reasons: 1. The grounding of the secondary side of a transformer is done through the neutral point, rather than through the phase wires. Neutral point grounding is intended to maintain circuit balance, rather than causing a short circuit to ground. 2. The secondary side of the transformer is isolated from the primary side by an insulator; therefore, under normal conditions, no current will flow through the insulator to the ground. 3. The secondary side of transformers generally uses well-insulated wires to ensure that current does not flow from the wires to the ground. In short, grounding one end of the secondary side of a transformer does not cause a ground short circuit, provided that the transformer is functioning properly and the grounding method is correct. If the transformer malfunctions or the grounding method is improper, it may lead to a ground short circuit. Therefore, when using transformers, operations must be carried out strictly in accordance with relevant specifications and standards. .

It will not form a circuit with the main power supply. No circuit is formed with the primary side of the current transformer; of course, if both secondary terminals are grounded, it will still result in a short circuit
