Subject = New: SDS Transformer Grounding Drawings


The following drawing depicts Grounding the Secondary "X0" terminal of a
typical 480 x 208Y/120V 3 Phase 4 Wire Wye Transformer
( a Separately Derived System ):



Figure 1a: Front View of the Transformer.

Notice the internal Transformer Winding Connections.




Figure 1b: Top View of the Transformer.

Notice the incoming Branch Circuitry on the Right Side,
and the outgoing SDS Circuitry on the Left.

BTW, the Grounding Electrode Conductor is coming in from the back.
