Provat e ndotjes artificiale në izoluesit e tensionit të lartë që përdoren në sistemet e rrymës alternative

Artificial pollution tests on high-voltage insulators to be used on a.c. systems

Scope

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 ranging from 1 000 V up to 765 kV. These tests are not directly applicable to greased insulators or to special types of insulators (insulators with conductive glaze or covered with any organic insulating material).
