A method for identifying dielectric response parameters of stator windings insulation in pumped storage generator-motor based on modified SPDMD of depolarization current

•The paper proposes a dielectric-parameter method based on depolarization-current modal decomposition, selecting dominant modes.•The method automatically infers branch count in the EDM, minimizing prior knowledge and keeping physical relevance.•Adaptive filtering separates dominant relaxation modes...
