About this module

This module picks up exactly where design ends: installation sequencing on a utility-scale project, transformer field tests compared against the factory baseline, and the full breaker and protective relay test suite — timing, contact resistance, secondary injection against the Module 9 coordination study, and primary injection to verify what secondary injection can't reach.

It closes with cable acceptance testing (VLF withstand, tan delta, partial discharge), fall-of-potential ground grid testing against the IEEE 80 design, and the energization sequence itself — because the complete commissioning test record compiled here is exactly what Module 16's operations and maintenance program trends against for the life of the equipment.
