Re: Separately Derived System
A winding to winding fault on the end user transformer will flow through the premises wiring back to the exterior distribution transformer.
The only way to prevent this from occurring is to feed the primary of the distribution transformer with an ungrounded secondary from another source.
This connection will make the only electrical connection to the premises served by magnetic induction. The definition of a separately derived system.
