摘要
Space charge distribution in cross-linked polyethylene (XLPE) subjected to a uniform field at 50 mHz is determined with the Phase Resolved PEA technique. It is shown that at almost all phase angles of the ac waveform more space charge is injected into XLPE at 50 mHz than at 50 Hz. The amount of charge due to only one ac cycle at 50 mHz is larger than that due to 1000 cycles at 50 Hz. At 50 mHz the local field in XLPE is in synchronization with the applied field.
