Additional Test Methods for Dielectric Testing

The previous post provided test methods for dielectric breakdown and dielectric strength at commercial ac frequencies, i.e., 60Hz. Here are two additional test methods to be used for dc testing and impulse testing.

IEC 60243-2 gives requirements additional to those in IEC 60243-1 for the determination of the electric strength of solid insulating materials under direct voltage stress.

For impulse testing, see IEC 60243-3, which gives requirements additional to those in IEC 60243-1 for the determination of the electric strength of solid insulating materials under 1,2/50 ms impulse voltage stress.
