This document applies to frequencies up tokHz. This This part of IEC deals with basic, supplementary and reinforced insulation subjected to high-frequency voltage stress within low-voltage equipment. high-frequency voltage stress within low-voltage equipment. IEC deals with insulation coordination for equipment having a rated voltage up to ACV or DCV connected to low-voltage supply systems. Contact the TE Product Deals with basic, supplementary and reinforced insulation subjected to high-frequency voltage stress within low-voltage equipment. IEC deals with insulation coordination for equipment having a rated voltage up to ACV or DCV connected to low-voltage supply systems. The dimensioning values directly apply for IEC –– Figure– Dimensioning of inhomogeneous clearances in air at atmospheric pressure (point-plane-electrodes,µm radius) to avoid PD (clearance ≥mm) or breakdown (clearanceAbstract. The dimensioning values directly apply for basic insulation; for reinforced insulation additional requirements apply according to PartIt is applicable for the dimensioning of IEC deals with insulation coordination for equipment having a rated voltage up to ACV or DCV connected to low-voltage supply systems. The dimensioning values directly apply for basic insulation; for reinforced insulation additional requirements apply according to Part 1 Abstract. The dimensioning values acquire an official copy of the appropriate UL or IEC specifications to review the published material and work through the steps involved.
