Investigating Electrical Performance of Polyimide Insulation Tapes for Automotive Application

This paper shows results of a preliminary study about electric strength and electrical endurance properties of various types of polyimide tapes, including the corona-resistant ones, in the presence and absence of partial discharges. Feasibility of insulation design for applications, such as automotive, where the rated voltage is increasing significantly, and the presence of partial discharges during operating life is likely, in investigated, with apparently positive indications.
