IEC 60076
The IEC standard series defining requirements for power transformers, the global reference standard.
IEC 60076 is the comprehensive international standard for power transformer design, testing, performance, and application. Primary reference worldwide (Europe, Asia, Africa, South America).
Parts: -1 (General), -2 (Temperature Rise), -3 (Insulation/Dielectric Tests), -5 (Short-Circuit), -7 (Load Guide), -10 (Acoustics), -11 (Dry-Type), -20 (Energy Efficiency).
Differs from IEEE C57 in temperature rise notation, insulation levels, ratings, test procedures. Our IEC vs IEEE guide covers differences.
QDTB manufactures fully IEC 60076 compliant with complete type and routine testing. CE certification guide covers European compliance.
