Under general supervision, assist with collecting, compiling, and analyzing data from the physical work site, surveys, blueprints, schematics, data, verbal or written specifications, technical drawings, rough sketches, diagrams, and other matrices to support substation protection and control (P&C) design and drawing development activities. Under general supervision, use computer‑aided design and drafting (CADD) software to assist with basic design details and prepare substation P&C drawings which require a high degree of precision (e.g., control schematics, wiring diagrams, interconnection diagrams, panel layouts).
