Abstract

Disadvantages of existing methods for determining moisture content in insulating liquids used in laboratories of power plants are considered and revealed. A method is proposed for determining moisture content in liquid dielectrics based on the measurement of parameters of multielement two-terminal networks in steady-state and transient modes. The results of the studies as applied to transformer oils are presented.
