What do we mean by shielding in a Transformer

Shielding in a Transformer refers to the prevention of capacitive coupling between the primary and the secondary. It is usually a plate placed between the primary and the secondary.
If the shielding is not provided, there is a chance of capacitive coupling (with the insulation as the dielectric) between the primary and the secondary windings. This can result in high voltages being induced in the secondary winding.

Which is why, I surmise, The whole idea of grounding the secondary that fed the end user's wiring.... To avoid the possibility of the primary winding's high voltage, being capacitivly coupled to everything connected to the secondary... and people getting knocked on their butts !!!!!! (the secondary and all associated wiring would be floating above at the capacitively coupled voltage)
