I. Purpose
The high voltage leakage spark test machine is suitable for conducting tests on electrical products, household appliances and their materials regarding their resistance to electrical scarring and erosion. It simulates the process under industrial frequency (48Hz - 62Hz, using liquid contaminants and inclined test samples, through the measurement of electrical scarring and erosion to evaluate the electrical scarring and erosion grades of electrical insulating materials used in harsh environmental conditions. This machine is strictly designed and manufactured in accordance with GB/T6553-2003 and 1EC60587-1984.
