Root cause analysis is important when a transformer or magnetic component shows unexpected behavior in production, incoming inspection, or field operation. BaoHui Tech supports analysis by connecting test records, batch traceability, material data, drawings, process history, inspection results, and application conditions.
Good RCA Starts With Traceable Data
Without batch records and approved drawings, it is difficult to know whether a problem comes from design, manufacturing, material substitution, shipping damage, installation, or application stress.
A transformer manufacturer should be able to compare failed parts with approved samples, production test data, and process records to identify what changed.
RCA Inputs BaoHui Tech Reviews
BaoHui Tech uses both component-level and system-level information during investigation.
- Part number, drawing revision, batch number, test report, and shipment record
- Failure symptom, operating condition, load profile, temperature, and installation details
- Electrical tests such as turns ratio, inductance, leakage, resistance, hipot, and insulation resistance
- Visual inspection for terminals, insulation, discoloration, winding movement, corrosion, or mechanical damage
- Material lot, process records, change history, and corrective action plan
Corrective Actions Should Be Controlled
A corrective action may involve design revision, process change, material control, test-limit update, packaging improvement, or customer installation guidance.
Each change should be documented and validated before production release so the fix does not create a new risk.
