DOI: 10.1109/tim.2020.2984405
Abstract: Analysis of detrapped charge [evaluated from polarization–depolarization current (PDC)] is effective in carrying out insulation diagnosis. However, computation of detrapped charge requires PDC data for at least 1600 s (PDCs each measured for 800 s).… read more here.

DOI: 10.1109/tim.2022.3181286
Abstract: The depolarization current is critical for the computation of insulation-sensitive parameters of the transformer. Prolonged polarization–depolarization current (PDC) measurement times, on the other hand, can increase the likelihood of obtaining distorted original data as a… read more here.
