There are strong randomness and fuzziness between the symptom and the mechanism of power transformer failures, and due to the one-sideness in the consideration and imperfection of knowledge base it is often hard to meet practical requirement of power transformer fault diagnosis by the single diagnosis method. For this reason, based on respective diagnosis results by IEC-60599 three-ratio method, fuzzy diagnosis method, ant colony optimization (ACO) and grey system theory (GST) algorithm an optimal combined model is constructed to diagnose power transformer fault. Practical fault diagnosis exam...
