摘要：

Unusual conductive contaminants at oil-paper interface [particles, copper sulfide deposits, debris from previous faults, etc.] of transformers can be diagnosed by on-site off-line time-domain, Polarization Depolarization Current (PDC) measurement. Some results are presented in the case studies of this document.
