Abstract
When the short-time electric strength (E st) of low loss polymers is determined in accordance with IEC 243, breakdown is usually caused by `surface discharges´. Unless there are gross isolated defects, E st is more dependent on the thickness d than on the area of the samples. E st is affected by the permittivity and electric strength of the immersion medium and when d >0.1 mm, E st is usually higher when samples are tested in air than in a clean transformer oil
