?? In-depth analysis of the seven failure modes of high-frequency transformers | Engineers must read the guide ??
1. External Appearance Defects
Transformers undergo complex manufacturing processes. During production, the core and frame can suffer collisions during transport or processing, leading to cosmetic damage.
2. Voltage Withstand (Dielectric Strength) Issues
Voltage withstanding problems are one of the common electrical failures in transformers.
3. Inductance Issues
Inductance problems typically arise from:
4. Leakage Inductance Issues
Leakage inductance primarily develops during the winding process:
5. Winding Turns Defects
Problems with the number of turns are generally related to the calibration of automatic winding machines:
6. Inter-layer Short Circuit
Inter-layer short circuits are often due to process-related issues:
7. Resistance Issues
Resistance-related problems rarely occur unless:
Summary and Outlook ??
Transformers can fail in many ways, and any issue in a single stage can affect the performance of the final product. In production, it is crucial not only to have a refined process but also to enforce strict quality management and timely testing feedback to ensure every stage meets the standards. Through this detailed analysis, we hope engineers and technicians will better understand the critical quality indicators and provide a solid foundation for improving overall system performance. ??
