What We Inspect in Electrical Equipment
Full-stage inspection of power generation, transmission and distribution equipment, including FAT witnessing for transformers, switchgear and substation equipment.
Typical scenarios: Power plant projects, grid infrastructure upgrades, overseas EPC deliveries and utility procurement programs.
Scope
Detailed Inspection Scope
Power transformers (110kV and above) — FAT witnessing, type test review, routine test verification
Medium-voltage switchgear panels — documentation review, expansion line FAT witnessing
Substation equipment — circuit breakers, disconnectors, site arrival inspection
Generation and transmission equipment — full-stage quality verification
Methodology
Four-Stage Inspection Process

Stage 1 - Design & Document Review
Drawing audit, specification compliance, material certification verification
2
Stage 2 - In-Process Inspection
Winding, core assembly, tank fabrication, welding quality checks
3
Stage 3 - Factory Acceptance Test
Routine & type test witnessing, dielectric, temperature rise, partial discharge
4
Stage 4 - Site Arrival & Installation
Transport damage check, assembly supervision, commissioning support
