Isolated systems convert mechanical energy into electrical energy in a separated area.

There are applications where it is unsafe or impractical to run power wires into a space. Examples include explosive or corrosive atmospheres.

Another example where isolated power generation is a good solution is high voltage enclosures where it would not be practical to route power wires. Here, a shaft made of a nonconductive material can turn an alternator inside the box and provide power that is not tied to external ground.
