Artificial pollution tests on high-voltage ceramic and glass insulators to be used on d.c. systems

IEC TS 61245:2015(E) is applicable for the determination of the d.c. withstand characteristics of ceramic and glass insulators to be used outdoors and exposed to polluted atmospheres, on d.c. systems with the highest voltage of the system greater than +/- 1 000 V. These tests are not applicable to polymeric insulators, to greased insulators or to special types of insulators (e.g. insulators with semiconducting glaze or covered with any organic insulating material). The object of this technical specification is to prescribe procedures for artificial pollution tests applicable to insulators for overhead lines, substations and traction lines and to bushings. This second edition cancels and replaces the first edition published in 1993. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:a) Corrections and the addition of explanatory material;b) The addition of Clause 4.4.2 on atmospheric correction;c) The change of upper limit of volume conductivity of tap water for insulator cleaning to 0,1 S/m;d) The extension to UHV voltages; ande) The addition of Annex B "Determination of the withstand characteristics of insulators" and Annex E "Supplementary information on artificial pollution tests on insulators for voltage systems of +/- 600 kV and above (solid layer method procedure B).The contents of the corrigendum of August 2018 have been included in this copy.
