Accepted Answer

At least two earthing connections are required for a healthy distribution transformer system.

Distribution transformers require earthing to ensure safety and proper functioning.
At least two earthing connections are necessary to create a low-resistance path for fault currents.
One earthing connection is typically made to the transformer tank, while the other is connected to the neutral point of the transformer winding.
Earthing helps in dissipating fault currents, preventing damage to the transformer and ensuring the safety of personnel.
Additional earthing connections may be required depending on the specific system design and local regulations.
