Abstract: For transformer fault detection, a method generates a transition region that separates a health region and a fault region in a two-dimensional feature space of two feature indicators for a plurality of operation conditions using a fault detection model for a power transformer type. The method determines the feature indicators of a given power transformer of the power transformer type. The method determines whether the feature indicators in the transition region satisfy a fault condition. The method predicts an inter-turn short fault for the given power transformer in response to satisfying the fault condition or the feature indicators being in the fault region.
