The standard applies to both oil-immersed and dry-type power transformers as defined in IEC 60076-1 . Its primary goal is to ensure that a transformer can survive various fault conditions, including: Three-phase short circuits. Line-to-line and line-to-earth faults. Double-earth faults.
A transformer that fails to meet this standard may experience cumulative winding loosening over years of minor faults, eventually leading to a catastrophic failure. Thus, IEC 60076-5 is not a bureaucratic hurdle—it is a prerequisite for long-term grid stability.
: The standard provides specific calculation procedures to demonstrate that the transformer will not exceed critical insulation temperature limits during the fault.
Disadvantages: Extremely costly; carries a risk of damaging the unit during the test; requires specialized facilities that are rare worldwide.
