IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.A semantic‐guided unsupervised domain adaptation network (UDAN) is proposed for label‐free partial discharge severity assessment in gas‐insulated switchgear. The method combines PD measurement signals and inspection‐record semantics to achieve robust cross‐domain condition assessment through feature alignment and adversarial adaptation.
