Execution notes
From site, in plain terms.
Coordinated with MSEDCL field staff for outage planning and feeder synchronization. Civil interface managed in parallel with electrical erection to compress schedule.
Pre-commissioning tests included transformer winding resistance, magnetic balance, vector group, oil BDV, IR and HV tests on switchgear, and primary injection on CTs.
Final SAT documented to MSEDCL format. Handover included as-built drawings, test certificates and DLP support agreement.
