Polyimide (PI) is an important insulation material due to its high thermal, chemical and electrical resistance along with good mechanical strength [1]. It has been widely used in equipment such as high voltage motors, wind turbine and aerospace craft [2]. In this work, nanostructured PI tapes have been subjected to thermal aging. The PD Inception Voltage (PDIV) and the tape endurance under PD bombardment were considered as the key quantities to assess its performance. Dielectric spectroscopy, conductivity tests and SEM imaging were employed to analyze the effect of thermal aging on PI and explain its impact on the PD endurance.
