CASE STUDY REPORT
3.3kV Power Transformer Oil Centrifugal Filtration
Executed on-site vacuum dehydration and centrifugal oil filtration across two 2.5 MVA substation transformers, restoring dielectric breakdown voltage (BDV) from 24kV to 72kV without plant shutdowns.
Quality Verification & Delivery:
All repaired units pass full-load no-load telemetry, megohmmeter insulation resistance checking (>100 MΩ), polarization index (PI) verification, and dynamic vibration analysis before dispatch to client facilities.
