Dielectric Strength Apparatus

Apparatus to perform destructive and nondestructive dielectric strength tests. The dielectric strength is defined as the maximum intensity of the electric field supplied to an insulating material without causing breaks (perforations). The physical breakdown of the material is emphasized by a sudden and irreversible resistance decrease, usually followed by the destruction of the material Resistance to perforation of insulating material through suitable electrodes, with application of alternate current.kV/mm or kV/cm are the typical measurement units used.
