Where an underground electrical distribution system is most likely to be found is underground.
In a built up city centre.
In an upscale neighborhood.
Yes, many large buildings are built with electrical vaults to house the electrical distribution system. The high voltage enters the building usually underground, where it connects to a transformer. The secondary side of the transformer is connected to a distribution system where the supply voltage is then sent to the individual apartment sub panels.
The rising mains are essentially used in electrical distribution system in buildings two storied and above. It is basically used in indoor applications. Nowadays vertical type distribution is normally used as it is more convenient and reliable compared to rising cable system.
Quad ring main unit (QRM) is used to connect 2 no. transformers at their high voltage side to the distribution system.
A step up transformer is used at this junction in the electrical transmission system.
All electrical distribution systems require a system earth ground for personnel safety. The ground for your home electrical system is likely a grounding rod, a 10 ft. copper clad steel rod driven into the ground and then bonded with a brass clamp and large bare ground wire to your panel. This provides a path to ground to dissipate errant current which can occur due to a circuit which "shorts out." Better it goes to ground than into you!

Primary line power distribution system.

providing mission essential power
a path through which power is transferred from generating station to consumers.
The electrical energy generated at the generating station reaches the consumer through the transmission and distribution systems. The transmission system generally consists of overhead transmission lines, towers, safety equipment and transformers and is used to transmit the generated electricity to the load centres (i.e. places where electrical energy is consumed). This energy is then distributed to various consumers using the distribution system - which consists of underground cables, overhead lines, transformers, safety equipment etc etc...

A certified electrician builds the service distribution to code specifications. An electrical inspector inspects the job and when it is approved he submits a declaration to the utility company for connection to the electrical grid.

Thomas Alva Edison developed detailed plans for an entire distribution system for electric power.
Depends how ratty the electrical system is and how careless the occupants are.
