OSTI ID:6352507

This method covers a referee and a routine procedure for determining the dielectric breakdown voltage of insulating liquids. These procedures are applicable to liquid petroleum oils, hydrocarbons, and askarels commonly used as insulating and cooling mediums in cables, transformers, oil circuit breakers, and similar apparatus. The suitability of these procedures for testing liquids having viscosities exceeding 900 cSt (mm/sup 2//s) (5000 SUS) at 40/sup 0/C (104/sup 0/F) has not been determined. This method is recommended for acceptance tests on unprocessed insulating liquids received from vendors in tank cars, tank trucks, and drums. It may also be used for the routine testing of liquids from power systems apparatus rated 230 kV and below. This method is not recommended for testing filtered, degassed, and dehydrated oil prior to and during the filling of power systems apparatus rated above 230 kV, or for testing samples of such oil from apparatus after filling. Method D 1816 is more suitable for, and is recommended for, testing such oils.
