Measurement of relative permittivity, dielectric dissipation factor and d.c. resistivity of insulating liquids — 32 стр.
Covers the whole subject of the measurement of dielectric properties of insulating liquids. Applies to hydrocarbons and askarels as well as to other liquids for which alternative cleaning procedures may be required. The measurement methods are primarily intended for making reference tests on unused liquids, but they may also be applied to liquids in service.
