DIN EN 60507:2014-09

This standard is applicable for the determination of the power frequency withstand characteristics of ceramic and glass insulators to be used outdoors and exposed to polluted atmospheres, on a.c. systems with the highest voltage of the system greater than 1 000 V. These tests are not directly applicable to polymeric insulators, to greased insulators or to special types of insulators (insulators with semiconducting glaze or covered with any organic insulating material). The object of this standard is to prescribe procedures for artificial pollution tests applicable to insulators for overhead lines, substations and traction lines and to bushings. It may also be applied to hollow insulators with suitable precautions to avoid internal flashover. In applying these procedures to apparatus incorporating hollow insulators, the relevant technical committees should consider their effect on any internal equipment and the special precautions which may be necessary. The following modifications have been made with respect to DIN EN 60507 (VDE 048-1):1994-04: a) corrections and the addition of explanatory material; b) the addition of 4.4.2 on atmospheric correction; c) the change of the upper limit of conductivity of water to 0,1 S/m and d) the extension to UHV voltages. The responsible committee is DKE/K 451 "Isolatoren" ("Insulators") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
