Construction of the infrastructure for evaluating characteristic against contamination for power installation

In this paper, there have been brief review about the important consideration in laboratory planning and construction of the artificial pollution testing facilities including 300 kV, 1800 kVA AC test system, which enable to lest and evaluate the UHV dielectric performance of power insulators up to transmission class. Also it is described simply about its trial running of the whole test system. To evaluate the performance characteristics against contamination for various power installation, especially for the insulators and kinds of bushings, brief investigation and an analysis of test objects and related international codes and standards have been conducted.
