Partial discharge risk becomes important in high-voltage transformer designs where insulation stress, voids, sharp edges, contamination, or poor spacing can reduce long-term reliability. BaoHui Tech reviews insulation structure and production process carefully when a transformer must operate with elevated voltage stress.
Why Partial Discharge Matters
Partial discharge is a localized electrical discharge that does not fully bridge insulation but can progressively damage insulating materials. It is a concern in high-voltage power transformers, high frequency transformers, medical or test equipment, and specialized industrial power systems.
Risk depends on voltage waveform, rise time, insulation material, geometry, trapped air, potting quality, creepage, clearance, and environmental conditions.
Design and Process Controls
BaoHui Tech reviews high-voltage transformer construction with attention to both design geometry and production repeatability.
- Working voltage, transient voltage, waveform rise time, and safety standard
- Creepage, clearance, insulation thickness, margin tape, and sleeving
- Winding geometry, edge treatment, lead routing, and shield placement
- Potting or impregnation process, void control, curing, and material compatibility
- Hipot, insulation resistance, partial discharge testing if required, and visual inspection
Validation and Documentation
Not every transformer requires partial discharge testing, but high-voltage or high-reliability applications should define the expected test method and acceptance criteria early.
Production documentation should control material selection, insulation placement, potting process, and inspection points. These details are central to long-term insulation reliability.
