IEC 60076-5 specifies requirements and test procedures to verify a power transformer’s mechanical and electrical ability to withstand internal short-circuit forces without catastrophic failure. Its scope covers design, manufacturing and testing provisions intended to ensure transformers remain safe and retain containment of energized parts during and after a short-circuit event.
Analysis of transformers that failed short-circuit tests (or real faults) reveals recurring issues: iec 60076-5
