Checking Axial Deviation
Axial deviation — also called runout or eccentricity — is the measure of how much the end fitting centerline deviates from the insulator body centerline. This parameter directly affects load distribution. IEC standards specify maximum permissible axial deviation as a function of insulator length and type.
