Transformers don't prevent shock
I am guessing at this one but probably to warm the oil so as to assure proper flow and prevent thermal shock once the transformer and its components are heated up under load.

To prevent electrical shock, you should connect the ground wire first.
yes!
Your doorbell transformer may be buzzing due to loose wiring, a faulty transformer, or excessive load on the transformer. It is important to address this issue promptly to prevent any potential safety hazards.

Yes, rubber gloves can help prevent electric shock by providing insulation and protection against electrical currents.
the function of shock absorber is to prevent the coil spring or the spring bar to move freely or to prevent them to bounce as it is.that is why they put shock absorber to have a good riding comfort depends on the road condition
Not necessarily -only if you come into contact with the source voltage. But it won't do the transformer any good, as they only work on a.c. Attach a d.c. supply at its rated voltage, and you'd likely burn out the transformer's primary winding,
To prevent getting an electric shock from a door handle, you can touch a metal object like a key or a coin to discharge any static electricity before touching the handle. This will help prevent a shock by equalizing the charge between you and the handle.
Transformers are typically grounded at the transformer’s neutral point, which is the point where the windings are connected to the ground. This grounding helps to prevent overvoltages, provides a return path for fault currents, and enhances system stability. Additionally, grounding can occur at the transformer’s frame or enclosure to ensure safety and minimize the risk of electrical shock. Proper grounding practices depend on the specific application and local electrical codes.
