Thermal ageing and its impact on charge trap density and Insulating properties in LDPE

Charge density plot
High Voltage Engineering, Space and surface charge

In our research, we intend to explore the relationship between ageing and trapping parameters and use the initial trapping parameters and breakdown strength to infer breakdown behaviour after ageing, which means trapping parameters can be utilized to assess the ageing degree of insulation in HVDC system and predict its lifetime.
