Dielectric strenght
This method is used to assess the dielectric strength of an insulating material.
It calculates the voltage at which a harmonic alternating voltage collapses upon destruction of the insulating material.
Test specimen | usually Ø 80 mm, 2 mm thick |
Max. test voltage | 100 kV (50 Hz) |
Current on breaking | 40 mA |
Surrounding medium | Insulating oil |
Electrode pairs | Plate/plate Ball/ball Ball/plate |
