HIGH LEVEL SCOPE OF WORK - PTM&C EQUIPMENT FOR WESKUSFLEUR SUBSTATION - Report Revision 1

Sep 12, 2026

Uploaded by Ivy

High Level Scope of Work defines the engineering documentation for PTM&C equipment for the Weskusfleur substation, including authorization, compilation roles, and revision control. It provides a structured scope covering general background, detailed protection scope, sourcing and engineering resources, and multiple breaker-and-a-half interface and protection scheme requirements. The scope extends to marshalling kiosks and feeder protection requirements across 400 kV and 132 kV lines, plus generator and auto transformer protection and control schemes.
