All basic mutual Transformers have a laminated silicon-steel core, around which are placed a primary winding and a secondary winding.
Practical transformers can be much more complicated. They may contain multiple windings, terminal bushings, tap-changing mechanisms, oil-cooling arrangements, and protective devices.
the pocket substation have three major parts and they are transformer , ring main unit (RMU) and low voltage distribution bored (LVDB).
A step-down transformer does just what it's designed to do, so there are no 'major' faults associated with it.
Physicially it has transformer tank, conservator, bucholz relay , windings, oil
Because the electrical parts of a transformer do not move / rotate.
An earthing transformer provides a neutral in a delta connected system.
A major internal short circuit has been known to burst the tank of a transformer; but it can apply to any transformer -not just a 'step-down' type.
b'coz transformer is not a moving parts so it works on the princeple of mutual induction
major parts
Vanguard, Tettex, AEMC are major ones for transformer market.

The major parts of the rocket car is the engine and the wheels.
