Equivalence analysis of dielectric test methods in time domain and frequency domain
International Journal of Electrical Power & Energy SystemsWideband dielectric response is crucial for accurate assessment of insulation condition. However, time-domain measurements such as polarization and depolarization current (PDC) tests often lose high-frequency components, while frequency domain ...
