摘要

Ash dense(non-soluble sediment density,NSDD) is attached to the insulator surface material that can’t dissolve in water,it is divided by the result of surface area and used for quantitative content of insulator surface non-soluble residues. Based on high voltage measurement,surface of outer insulation of ash can be used for the product line insulator pollution situation and determine whether it is able to withstand a variety of adverse factors. This paper proposes a method based on BH1750 FVI light intensity sensor for ash dense measurement.
