Tracking and erosion test 1 000 h salt fog test are described. A test method includes more multiple stresses 1 000 h salt fog test methods shall be chosen to verify the resistance of an insulator design to the stress of electrical discharge activity. The test is a time-limited continuous test in salt fog at constant power-frequency voltage. Test chamber The test is carried out in a moisture-sealed corrosion-proof chamber, the volume of which shall not exceed 15 m 3 . An aperture of not more than 80 cm 2 shall be provided for the natural exhaust air. Fog generation : A turbo sprayer (room humidifier) of constant spraying capacity shall be used. |
