Transformers are designed to withstand occasional through-faults, but repeated or severe fault currents can significantly accelerate mechanical and dielectric aging, reducing long-term reliability. Traditional protection schemes operate on a binary principle-either tripping or not tripping-without capturing valuable information about fault severity, frequency, and cumulative impact. Online condition monitoring closes this gap by measuring, calculating, and trending through-fault stress over the transformer’s lifetime.
In this 60-minute webinar, we will explore:
- Evidence-based inspection triggers: inspections only after significant cumulative stress, not after every fault.
- Fleet prioritization: identify transformers at higher risk due to accumulated short-circuit aging.
- Improved protection coordination: real fault stresses compared with IEC/IEEE withstand limits.
- Extended lifetime: avoid premature retirement by quantifying real mechanical wear instead of assuming worst-case.
