Fast extremum values calculation of electro‑thermal fields for ±800 kV valve‑side resin-impregnated paper bushing under multiple factors

Valve-side resin-impregnated paper (RIP) bushings are key insulation components of HVDC converter transformers. Combined AC–DC voltage, high current, and varying thermal boundaries produce non-uniform electro-thermal fields, potentially causing local overheating and electric-fiel...
