A Study of Some Variables Affecting Contamination Testing Using the Wet Contaminant Method

The test results reported in [1] for which Cab-O-Sil®was used as a slurry binder are compared with tests made using a slurry having a binder of kaolin and bentonite. Also investigated were the effect of nonuniformity of the contaminating coating and the strength of horizontal versus vertical contaminated insulator strings.
